Answer:
D[tex]_o[/tex] of Y = (-3/2, -1)
Step-by-step explanation:
We are given three points on the graph:
X (4, 0)
Y (3, 2)
Z (2, 2)
and the scale factor of dilation which is [tex]-\frac{1}{2}[/tex].
Given that, we are to find the coordinates of Y after dilation. To find that, we will multiply the coordinates of the point Y with the scale factor.
Y = [tex](-\frac{1}{2}[/tex] × [tex]3[/tex] , (-\frac{1}{2}[/tex] × [tex]2)[/tex]

Simplify 4(x + 7) – 7x + 2
Answers
Answer:
(-3x+30)
Step-by-step explanation:
We first distribute: 4(x+7) = 4x+28
Then, we bring it down.
4x+28-7x=2
Combine like terms.
4x+(-7x) = -3x ... 28+2 = 30.
Combine both results.
-3x+30
Answer:
[tex]-3x+30[/tex]
Step-by-step explanation:
We have been given an expression [tex]4(x+7)-7x+2[/tex]. We are asked to simplify our given expression.
Using distributive property [tex]a(b+c)=ab+ac[/tex], we will get:
[tex]4*x+4*7-7x+2[/tex]
[tex]4x+28-7x+2[/tex]
Combine like terms:
[tex]4x-7x+2+28[/tex]
[tex]-3x+30[/tex]
Therefore, the simplified form of our given expression would be [tex]-3x+30[/tex].

Answers
Answer:
7^4
Step-by-step explanation:
We are multiplying 7 together 4 times
7*7*7*7
The exponent represents how many times we are multiplying it together.
7^4
Answer:
[tex]7^4[/tex]
Step-by-step explanation:
A mathematical expression written in the form [tex]a^x[/tex] is said to be an exponential expression where [tex]a[/tex] is a constant called the base and [tex]x[/tex] is a variable.
Here we are given a numerical expression 7.7.7.7 which can also be converted into an exponential expression where base would be 7 while the value of its exponent will be 4 since the number 7 is occurring 4 time.
Therefore, the exponential expression will be [tex]7^4[/tex]
The functions f(x) and g(x) are defined below.
Which expression is equal to f(x) · g(x)?
Answers
none of the above
Step-by-step explanation:This question wants you to see that the radical can be simplified because it is ...
[tex]f(x)=\sqrt{(x+6)^2}[/tex]
The answer choices show you are expected to simplify this to ...
... f(x) = x +6
Then
... f(x)·g(x) = (x+6)(x³ -12) = x⁴ +6x³ -12x -72 . . . . . matches choice C
_____
However,
... f(x) = |x+6| . . . . . . . √(x^2) = |x|, the positive root regardless of sign of x
so the product f(x)·g(x) only matches selection C for x≥ -6. It matches the opposite of selection C for x ≤ -6.
The attached graph shows this. It graphs f(x), g(x), f(x)·g(x) (as a purple curve), and selection C (as orange dots).
The cost of going to the big playland park for a family is given by C = 15x + 50, where C represents the cost and x represents the number of family members. How much would it cost for 10 family members to go?
A) $3
B) $4
C) $100
D) $200
Answers
C=15(10)+50
C=150+50
C=200
The cost is D) $200
D ) $200
It would cost 10 family members a total of $200 to go to the big playland park.
STEP-BY-STEP EXPLANATION:
Let's first establish that the cost of going to the big playland park for a family is given by the following equation.
C = 15x + 50
Where C = total cost of going to the big playland park for a family
Where x = no. of family members going to the big playland park
From this, we will substitute the value given from the problem for ( x ) into the formula to obtain the value of ( C ).
C = 15x + 50
x = 10
THEREFORE:
C = 15 ( 10 ) + 50
C = 150 + 50
C = 200

A tourist starts to walk up a mountain path that is 31 miles long at the rate of 4 miles per hour. After walking for a while, he gets tired and decides to get a taxi. The taxi gets him to the top travelling at a constant speed of 50 mph. If the tourist reaches the destination 2 hours after he started, what distance does he have to pay the cab driver for?
Answers
Answer: 25 miles
Step-by-step explanation:
Since, the total distance = 31 miles.
Let he walks x miles at the rate of 4 miles per hour.
⇒ he walks remaining (31-x) miles at the rate of 50 miles per hour.
According to the question,
[tex]\frac{x}{4} + \frac{31-x}{50} = 2[/tex]
⇒ [tex]\frac{25x}{100} + \frac{62-2x}{100} = 2[/tex]
⇒ [tex]\frac{25x+62-2x}{100}= 2[/tex]
⇒ [tex]\frac{23x+62}{100}= 2[/tex]
⇒ [tex]23 x + 62 = 200[/tex]
⇒ [tex]23 x = 200 - 62[/tex] ( by subtracting 62 on both sides )
⇒ [tex]23 x = 138[/tex]
⇒ [tex]x=\frac{138}{23}[/tex] ( Dividing both sides by 23 )
⇒ [tex]x = 6[/tex]
Thus, the distance he pays to the cab driver = 31-x= 31 - 6 = 25 miles.
Therefore, He pays to the cab driver for 25 miles.
Distance that must be paid to the taxi = 25 miles
Further explanationLinear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration
• At constant velocity motion:
the speed of vo = v = constant
acceleration = a = 0
Δx = vt or x = xo + vtAn equation of constant velocity motion
[tex]\large {\boxed {\bold {x = v \times \: t}}}[/tex]
x = distance = m
v = speed = m / s
t = time = seconds
so
[tex]\rm t=\dfrac{x}{v}[/tex]
A mountain path is 31 miles long
The distance traveled by tourists = x1
The distance traveled taxi = x2, such that
x1 + x2 = 31
x1 = 31-x2
total travel time (t) = 2 hours
tourist speed = v1 = 4 mph
taxi speed = v2 = 50 mph
time taken by tourists = t1
[tex]\rm \dfrac{x1}{v1}=\dfrac{x1}{4}[/tex]
the time taken by taxi = t2
[tex]\rm \dfrac{x2}{v2}=\dfrac{x2}{50}[/tex]
total time = t1 + t2
[tex]\rm 2=\dfrac{x1}{4}+\dfrac{x2}{50}\\\\2=\dfrac{25x1+2x2}{100}\\\\200=25(31-x2)+2x2\\\\200=775-25x2+2x2\\\\575=23x2\\\\x2=\boxed{\bold{25~miles}}[/tex]

Please help with this math problem for trig. A 6 m ladder is leaning against a wall. The base of the ladder is 1.5 m from the wall. Calculate how high up the wall the ladder reaches.
Answers
Answer:
a = 5.81 m
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2
where b= 1.5 and c= 6
a^2 +1.5^2 = 6^2
a^2 +2.25 = 36
Subtract 2.25 from each side
a^2 +2.25-2.25 = 36-2.25
a^2 = 33.75
Take the square root of each side
sqrt(a^2) = sqrt(33.75)
a = 5.809475019
We only take the positive root because length must be positive
A system of equations is graphed on a coordinate plane.
Which coordinates are the best estimate of the solution to the system of equations?
(6, 0)
(0, 5)
(1, 4)
(1, 5)
Answers
Answer:
Option C is correct.
(1, 4)
Step-by-step explanation:
A system of equation is given :
2x + 3y =12 .....[1]
4x + 2y =10 .....[2]
Multiply equation [1] by 2 both sides we get;
[tex]2(2x+3y) = 2(12)[/tex]
Using distributive property i,e [tex]a \cdot(b+c) = a\cdot b+ a\cdot c[/tex]
4x + 6y = 24 .....[3]
Subtract equation [2] from [3] to eliminate x we get;
4x + 6y - 4x - 2y= 24 - 10
Combine like terms;
4y = 14
Divide both sides by 4 we get;
y = 3.5
Substitute the value of y in equation [1] we have;
2x + 3(3.5) =12
2x + 10.5 = 12
or
2x = 12 -10.5
2x = 1.5
Divide both sides by 2 we get;
x = 0.75
Solution = (0.75 , 3.5)
Best estimate solution = (1, 4)
Therefore, the best estimate solution of the given system of equation is, (1, 4)
Answer:
1,4 is the best estimate.

There isn't any number that x can't be. Start with a graph to show how this could be so.
It is easy to see that x > 0 gives a line that goes very near the x axis. It is not quite so easy to see that it never touches the x axis. But if you recreate the graph in Desmos, you will see that is true if you spread the x's out.
It is not quite so easy to see that when x<0 the graph tips upward very quickly but again if you move the values of the axis around you will see there is no value that x cannot be.

What you need to do here is pick an answer that will result in a decrease. If you have something like 1.3 * e ^ (0.038 * t), what will happen when t = 20
P = 1.3 * e^(0.038*20) = 1.3*e^0.76 = 2.77 which is getting bigger not smaller.

Answer:
135 Miles
Step-by-step explanation:
Answer:
At the nearest mile, stations B and C are 75 miles apart.
Step-by-step explanation:
In the attached image we can see all the three stations. The closest distance between stations B and C would be a straight line that can be calculate using the Cosine Rule:
[tex](BC)^2=(AB)^2+(AC)^2-2(AB)(BC)cos(\alpha)[/tex]}
Where:
AB is the distance between stations A and B
AC is the distance between stations A and C
α is the angle formed between the AC and AB railway lines
[tex](BC)^2=(105)^2+(85)^2-2(105)(85)cos(45)[/tex]
[tex]BC=75.02 miles[/tex]
So, at the nearest mile, stations B and C are 75 miles apart.
The length of the base and the height of a triangle are numerically equal. Their sum is 30 less than the number of units in the area of the triangle. Find the area of the triangle.
Answers
Answer:
50 sq. units
Step-by-step explanation:
The length of the base and the height of a triangle are numerically equal.
Let us assume that, the length and height as x.
So the area of the triangle will be,
[tex]\text{Area}=\dfrac{1}{2}\cdot \text{Base}\cdot \text{Height}=\dfrac{x^2}{2}[/tex]
As their sum is 30 less than the number of units in the area of the triangle, so
[tex]\Rightarrow x+x=\dfrac{x^2}{2}-30[/tex]
[tex]\Rightarrow 2x=\dfrac{x^2}{2}-30[/tex]
[tex]\Rightarrow 4x=x^2-60[/tex]
[tex]\Rightarrow x^2-4x-60=0[/tex]
[tex]\Rightarrow x^2-10x+6x-60=0[/tex]
[tex]\Rightarrow x(x-10)+6(x-10)=0[/tex]
[tex]\Rightarrow (x+6)(x-10)=0[/tex]
[tex]\Rightarrow (x+6)=0,(x-10)=0[/tex]
[tex]\Rightarrow x=-6,x=10[/tex]
Neglecting negative roots,
[tex]\Rightarrow x=10[/tex]
Hence, the base and height of the triangle is 10 units, so the area will be,
[tex]\text{Area}=\dfrac{1}{2}\cdot \text{Base}\cdot \text{Height}=\dfrac{1}{2}\cdot 10\cdot 10=50\ unit^2[/tex]

What is the full price of 90 tablets of "Drug Y", assuming your cost for 500 tablets is $425.00 with a 28% markup and a dispensing fee of $4.85 ?
Answers
Answer: Full price of Drug Y = $98.793
Step-by-step explanation:
Cost of 500 tablet = $425
28% markup = 425 * 28/100
= $119
Cost + markup = $425 + $119 = $544
Cost + markup + dispensing fee = $544 + $4.85 = $548.85
Full price of 500 tablet = $548.85
Full price of 1 tablet = $548.85/500
=$1.0977
Full price of 90 tablet = $1.0977 * 90
= $98.793
