Answer:
11x-6y
Step-by-step explanation:
we ignore the parenthesis so we add 8x and 3x since they are both positive which adds up to 11x
for -2y and -4y we add, a negative and a negative equals negative therefor -2y+(-4y)= -6y
11x-6y
For this case we must add the following expressions:
[tex](8x-2y) + (3x-4y) =[/tex]
We eliminate the parentheses, taking into account that:[tex]+ * + = +\\+ * - = -\\8x-2y + 3x-4y =[/tex]
We add similar terms:
[tex]8x + 3x-2y-4y =[/tex]
Equal signs are added and the same sign is placed:
[tex]11x-6y[/tex]
Answer:
[tex]11x-6y[/tex]
Option C
The coordinates R(1, -3), S(3, -1) T(5,-7) form what type of polygon?
a right triangle
an acute triangle
an equilateral triangle
an obtuse triangle
Answer:
A right triangle
Step-by-step explanation:
Suppose a, b, c are the sides of a triangle,
If a² = b² + c² or b² = a² + c² or c² = a² + b²
Then the triangle is called a right angled triangle,
If a² + b² > c², a² + c² > b², b² + c² > a²
Then the triangle is called an acute triangle,
If a = b = c
Then the triangle is called an equilateral triangle,
If a² + b² < c², where c is the largest side of the triangle,
Then the triangle is called an obtuse triangle,
Now, In triangle RST,
By the distance formula,

ST = √40 unit,
TR = √32 units,
Since, ST² = RS² + TR²
Hence, by the above explanation it is clear that,
Triangle RST is a right angled triangle,
First option is correct.

Which best describes a system of equations that has infinitely many solutions
Answer:
see explanation
Step-by-step explanation:
Either both equations are equal or are multiples of each other
As an example consider the 2 equations
4x - y = 2 → (1)
- 12x + 3y = - 6 → (2)
Multiply (1) by - 3
- 12x + 3y = - 6 → (3)
Subtract (3) from (2) term by term
(- 12x - (- 12)x) + (3y - 3y) = (- 6 - (- 6)), that is
(- 12x + 12x) + 0 = - 6 + 6
0 = 0
This indicates the solution has infinite solutions
let x = k, k is a real number then from (1) y = 4x - 2 ⇒ y = 4k - 2
Thus (k, 4k - 2) will generate solutions to the system of equations

Zoe often orders party trays from her favorite Mexican food restaurant for company events. For a recent company party, she spent $239 on 4 burrito platters and 5 taco platters. For a company meeting, she spent $208 on 3 burrito platters and 5 taco platters. How much does each type of platter cost?
Each burrito platter costs $___ and each taco platter costs $___ .
Answer:
Each burrito platter costs $_31_ and each taco platter costs $_23__ .
Step-by-step explanation:
Let's first express both orders into equations. Let's simply use b for the burritos platters and t for the tacos platters:
4b + 5t = 239
3b + 5t = 208
We can use the subtraction method easily on this one:
4b + 5t = 239
-
3b + 5t = 208
==============
1b + 0t = 31
b = 31
So, the burrito platters ost $31 each.
Now, let's find how much are the tacos ones. Just take the first equation:
4(31) + 5t = 239
124 + 5t = 239
5t = 115
t = 23
Taco platters cost $23.
Let's test that with the second equation:
3b + 5t = 208
3(31) + 5(23) = 208
93 + 115 = 208
208 = 208
Verified!

A piece of ribbon is cut into two shorter pieces in the ratio 2.8:1.25. The divfference in the length of the two shorter pieces is 80.6 centimmeters. What is the length of the original piece of ribbon?
Answer:
210.6 cm
Step-by-step explanation:
Given that a piece of ribbon is cut into two shorter pieces in the ratio 2.8:1.25.
So that means length of the first smaller piece = 2.8x
and length of the second smaller piece = 1.25x
Then difference between their lengths = 2.8x-1.25x = 1.55x
Given that difference is equal to 80.6 centimeters then we get
1.55x=80.6
or x= 80.6/1.55
or x=52
then length of the original piece = 2.8x+1.25x
= 2.8*52+1.25*52
= 145.6+65
= 210.6 cm
Three cars are for sale.
Car A
£12380
Car B
£16760
Car C
£14580
The price of each car is rounded to the nearest £100.
Which price changes by the greatest amount?
Answer:
Car B
Step-by-step explanation:
Car B's price changes by the greatest amount (£40) when rounded to the nearest £100 among the three cars.
To determine which price changes by the greatest amount when rounded to the nearest £100, let's first calculate the rounded prices for each car:
Car A: £12380 rounds to £12400
Car B: £16760 rounds to £16800
Car C: £14580 rounds to £14600
Now, let's compare the differences between the original prices and the rounded prices:
- For Car A: £12400 - £12380 = £20
- For Car B: £16800 - £16760 = £40
- For Car C: £14600 - £14580 = £20
The greatest difference is £40, which occurs for Car B. Therefore, the price of Car B changes by the greatest amount when rounded to the nearest £100.

Which statement can you be sure is true
Answer:
the answer is C
Step-by-step explanation:
If x is an even number, the function f(x) = 2x − 1 gives an odd number. Identify the set of odd numbers corresponding to this set of even numbers: {0, 2, 4, 6, 8}. A. {3, 5, 7, 9, 11} B. {-1, 3, 7, 11, 15} C. {1, 3, 5, 9, 11} D. {5, 7, 9, 11, 13}
Answer:
B. {-1, 3, 7, 11, 15}
Step-by-step explanation:
The given function is [tex]f(x)=2x-1[/tex]
To find the corresponding odd numbers, we substitute the even numbers as x-values into the function.
When x=0, [tex]f(0)=2(0)-1=-1[/tex]
When x=2, [tex]f(2)=2(2)-1=3[/tex]
When x=4, [tex]f(4)=2(4)-1=7[/tex]
When x=6, [tex]f(6)=2(6)-1=11[/tex]
When x=8, [tex]f(8)=2(8)-1=15[/tex]
Therefore the set of odd numbers corresponding to this set of even numbers are {-1, 3, 7, 11, 15}
Answer:
B. {-1, 3, 7, 11, 15}
Step-by-step explanation:
In order to find the set of corresponding odd numbers then we have to put the even numbers one by one as we already know that x can only have even values..
So,
Putting x = 0
2(0) - 1
=0-1
= -1
Putting x=2
2(2) - 1
=4-1
=3
Putting x=4
2(4)-1
=8-1
=7
Putting x= 6
2(6) -1
=12-1
=11
Putting x=8
2(8)-1
=16-1
=15
So the corresponding set for {0, 2, 4, 6, 8} is {-1, 3, 7, 11, 15}
Hence, option B is the correct answer ..
If lines AB and CD are parallel, then angels c and e are?
A. complementary
B. congruent
C. corresponding
D. supplementary
Answer:
D
Step-by-step explanation:
Given that AB and CD are parallel lines, then
∠c and ∠e are same side interior angles and are supplementary
Answer:
D. Supplementary
Step-by-step explanation:
Consecutive Interior Angles Theorem:
If two parallel lines are cut by a transversal, then consecutive interior angles are supplementary.
Supplementary means the sum of the angles is 180 degrees.
Another name for consecutive interior angles is same side interior angles. The angles are on the same side of the transversal (in this case to the left) and they are in between the parallel lines which is the interior.
The difference between the roots of the equation 2x^2−5x+c=0 is 0.25. Find c.
Answer:
[tex]c=\frac{99}{32}[/tex]
Step-by-step explanation:
The given quadratic equation is [tex]2x^2-5x+c=0[/tex].
Comparing this equation to: [tex]ax^2+bx+c=0[/tex], we have a=2,b=-5.
Where: [tex]x_1+x_2=\frac{5}{2}[/tex] and [tex]x_1x_2=\frac{c}{2}[/tex]
The difference in roots is given by:
[tex]x_2-x_1=\sqrt{(x_1+x_2)^2-4x_1x_2}[/tex]
[tex]\implies 0.25=\sqrt{(2.5)^2-4(\frac{c}{2})}[/tex]
[tex]\implies 0.25^2=6.25-2c[/tex]
[tex]\implies 0.0625-6.25=-2c[/tex]
[tex]\implies -6.1875=-2c[/tex]
Divide both sides by -2
[tex]c=\frac{99}{32}[/tex]
Answer:
The value of c is 3.09375.
Step-by-step explanation:
Given : The difference between the roots of the equation [tex]2x^2-5x+c=0[/tex] is 0.25.
To find : The value of c?
Solution :
The general quadratic equation is [tex]ax^2+bx+c=0[/tex] with roots [tex]\alpha,\beta[/tex]
The sum of roots is [tex]\alpha+\beta=-\frac{b}{a}[/tex]
The product of roots is [tex]\alpha\beta=\frac{c}{a}[/tex]
On comparing with given equation, a=2, b=-5 and c=c
Substitute the values,
The sum of roots is [tex]\alpha+\beta=-\frac{-5}{2}[/tex]
[tex]\alpha+\beta=\frac{5}{2}[/tex] .....(1)
The product of roots is [tex]\alpha\beta=\frac{c}{2}[/tex] ....(2)
The difference between roots are [tex]\alpha-\beta=0.25[/tex] .....(3)
Using identity,
[tex]\alpha-\beta=\sqrt{(\alpha+\beta)^2-4\alpha\beta}[/tex]
Substitute the value in the identity,
[tex]0.25=\sqrt{(\frac{5}{2})^2-4(\frac{c}{2})}[/tex]
[tex]0.25=\sqrt{\frac{25}{4}-2c}[/tex]
[tex]0.25=\sqrt{\frac{25-8c}{4}}[/tex]
[tex]0.25\times 2=\sqrt{25-8c}[/tex]
[tex]0.5=\sqrt{25-8c}[/tex]
Squaring both side,
[tex]0.5^2=25-8c[/tex]
[tex]0.25=25-8c[/tex]
[tex]8c=25-0.25[/tex]
[tex]8c=24.75[/tex]
[tex]c=\frac{24.75}{8}[/tex]
[tex]c=3.09375[/tex]
Therefore, the value of c is 3.09375.
a new car is sold for its sticker value of $19,400. three years later the customer returns to the car dealership to trade the car in. she is told that her car now has a value of $12,105. what is the rate of decline in the value of the car? In your final answer, include all of your calculations.
Answer:
The rate of decline is [tex]r=0.1455[/tex] or [tex]r=14.55\%[/tex]
Step-by-step explanation:
we know that
The formula to calculate the depreciated value is equal to
[tex]D=P(1-r)^{t}[/tex]
where
D is the depreciated value
P is the original value
r is the rate of depreciation in decimal
t is Number of Time Periods
in this problem we have
[tex]P=\$19,400\\D=\$12,105\\t=3\ years[/tex]
substitute in the formula above and solve for r
[tex]\$12,105=\$19,400(1-r)^{3}[/tex]
Simplify
[tex](12,105/19,400)=(1-r)^{3}[/tex]
[tex](1-r)=\sqrt[3]{(12,105/19,400)}[/tex]
[tex]r=1-\sqrt[3]{(12,105/19,400)}[/tex]
[tex]r=0.1455[/tex]
Convert to percentage
[tex]r=14.55\%[/tex]

we know that
x+y+z+w=70 -----> equation A
x=6y ----> y=x/6 -----> equation B
x=10z ----> z=x/10 -----> equation C
w=2+x -----> equation D
substitute equation B, C and D in equation A and solve for x
x+(x/6)+(x/10)+(2+x)=70
Multiply by 60 both sides
60x+10x+6x+120+60x=4,200
136x=4,200-120
x=4,080/136
x=30 years
Find the value of y
y=x/6 -----> y=30/6=5 years
Find the value of z
z=x/10 ----> z=30/10=3 years
Find the value of w
w=2+x ----> w=2+30=32 years
Write the result in ascending order and separated by spaces
3 5 30 32

Find the value of x. Then find the measure of each labeled angle.
please help.
Answer:
x = 20; the labeled angles are 80° and 100° ⇒ the last answer
Step-by-step explanation:
* Lets revise some facts about a parallelism
- If two lines are parallel, and intersected by a line, there are 3
pair of angles are formed
1) Alternate angles equal in measures (corners of Z letter)
2) Corresponding angles equal in measure (corners in F letter)
3) Interior supplementary angles their sum is 180° (corners of U letter)
* Now lets solve the problem
∵ There are two parallel lines intersect by another line
- The formed U letter
∴ The labeled angles are interior supplementary angles
∴ Their sum = 180°
∴ 5x + 4x = 180° ⇒ add the like terms
∴ 9x = 180° ⇒ divide both sides by 9
∴ x = 20°
* Lets find the measure of the labeled angles
∵ The measure of one of them is 4x°
∴ Its measure = 4(20) = 80°
∵ The measure of the other is 5x°
∴ Its measure = 5(20) = 100°

Answer:
C. [tex]y=3\cdot 5^x[/tex]
Step-by-step explanation:
First two options show linear function and last two options show exponentioal functions. From the table you can see that
[tex]\dfrac{3}{5}=5\cdot \dfrac{3}{25}\\ \\3=5\cdot \dfrac{3}{5}\\ \\15=5\cdot 3\\ \\75=5\cdot 15[/tex]
This gives you that the function is exponential. Let the expression for the function be [tex]y=ab^x.[/tex] Substitute two values:
at x=0:
[tex]y=a\cdot b^0\\ \\3=a\cdot b^0\\ \\3=a\cdot 1\\ \\a=3[/tex]
at x=1:
[tex]y=a\cdot b^1\\ \\15=a\cdot b\\ \\15=3\cdot b\\ \\b=\dfrac{15}{3}\\ \\b=5[/tex]
Hence
[tex]y=3\cdot 5^x[/tex]
What is the 25th term of the arithmetic sequence where a1 = 8 and a9 = 48?
Answer: [tex]a_{25} = 128[/tex]
Step-by-step explanation:
You need to use this formula:
[tex]a_n = a_1 + (n - 1)d[/tex]
Where [tex]a_n[/tex] is the nth] term, [tex]a_1[/tex] is the first term,"n" is the term position and "d" is the common diference.
You must find the value of "d". Substitute [tex]a_1=8[/tex], [tex]a_9=48[/tex] and [tex]n=9[/tex] into the formula and solve for "d":
[tex]48 = 8 + (9 - 1)d\\48=8+8d\\48-8=8d\\40=8d\\d=5[/tex]
Now, you can calculate the 25th term substituting into the formula these values:
[tex]a_1=8[/tex]
[tex]d=5[/tex] and [tex]n=25[/tex]
Then you get:
[tex]a_{25} = 8 + (25 - 1)5[/tex]
[tex]a_{25} = 8 + 120[/tex]
[tex]a_{25} = 128[/tex]

Step-by-step explanation:
Answer:
Exactly one solution.
Step-by-step explanation:
We have been given a system of equations. We are asked to find the number of solutions for our given system.
[tex]y=x+2...(1)[/tex]
[tex]6x-4y=-10...(2)[/tex]
We can see that equation (1) in slope-intercept form of equation.
We will convert equation (2) in slope-intercept form of equation as shown below:
[tex]6x-6x-4y=-10-6x[/tex]
[tex]-4y=-6x-10[/tex]
Divide both sides by [tex]-4[/tex].
[tex]\frac{-4y}{-4}=\frac{-6x}{-4}+\frac{-10}{-4}[/tex]
[tex]y=\frac{3}{2}x+\frac{5}{2}[/tex]
We can see that slopes of both lines are different, therefore, our given lines will intersect exactly at one point and our given system of equations has exactly one solution.

[tex]a^{-n}=\frac{1}{a^n}[/tex]
Then, we can rewrite the expression in the following form:
[tex](5^{-6})^2=(\frac{1}{5^6})^2[/tex]
We also need to remember the Power of a power property, which states that:
[tex](a^n)^m=a^{(nm)}[/tex]
Then, applying this property, we get:
[tex]\frac{1}{5^{(6*2)}}=\frac{1}{5^{12}}[/tex]

The loan amount is 890 while the fee charged on the loan is 40. The amount repayable at maturity is thus;
890 + 40 = 930.
Therefore, he has to pay $930 by the time the loan reaches maturity.
Answer:
$930
Step-by-step explanation:
Daryl took out a single payment loan for $890.
That charged a $40 fee.
He takes loan of $890 that charged a $40 fee for a single time, so his maturity amount = loan amount + fees of $40
He have to pay by the time the loan reaches maturity = 890 + 40
= $930
He have to pay $930 by the time of maturity.
Write as a single logarithm
ANSWER
[tex]c. \ln( \frac{2 {x}^{3} }{3y}) [/tex]
EXPLANATION
We want to write
[tex] ln(2x) + 2 ln(x) - ln(3y) [/tex]
as a single logarithm.
Use the power rule to rewrite the middle term:
[tex]n \: ln(a) = ln( {a}^{n} ) [/tex]
[tex]ln(2x) + ln( {x}^{2} ) - ln(3y) [/tex]
Use the product rule to obtain:
[tex]ln(a) + ln(b) = ln(ab) [/tex]
[tex]ln(2x \times {x}^{2} )- ln(3y) [/tex]
[tex]ln(2{x}^{3} )- ln(3y)[/tex]
Apply the quotient rule:
[tex] ln(a) - ln(b) = ln( \frac{a}{b})[/tex]
[tex]ln(2{x}^{3} )- ln(3y) =\ln(\frac{2 {x}^{3} }{3y})[/tex]
Without using a protractor to measure exactly, choose the BEST possible measurement of the angle above.
A. 90°
B. 45°
C. 85°
D. 160°
Answer:
Step-by-step explanation:
The slanting line has a slope of approximately 1, so the angle this line makes with the horiz. axis is approx. 45 degrees.
Answer:
B
Step-by-step explanation:
It's not going to be a right angle. The two lines of a right angle are perpendicular. A is incorrect.
C is incorrect. 85o is pretty close to 90 degrees. That angle is nowhere's near that large.
D is incorrect. 160 degrees is nearly a straight line. The angle shown isn't.
That leaves B.
B looks to be 45 degrees and since the others are incorrect, B must be your answer.
