Simplify 4(x + 7) – 7x + 2
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].
A train leaves train station A and heads due west for 105 miles to reach train station B. Another train leaves train station A at the same time and travels 85 miles to train station C in a direction 45 north of west from station A. To the nearest mile, how far is train station C from train station B? 75 miles 109 miles 135 miles 176 miles
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 functions f(x) and g(x) are defined below.
Which expression is equal to f(x) · g(x)?
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).

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 ?
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

what is the domain of f(x) = (1/3)^x ?
Answer:
B
Step-by-step explanation:
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.

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)
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.

a regular size chocolate bar is 5 4/9 inches long. the king size bar is 3 times as long as the regular size bar. how long is the king size bar
Answer:
15 4/9 inches long
Step-by-step explanation:
5 4/9 × 3
When lining them vertically the 3 ends up under 5 in which you multiply and transfer the 4/9 next to the product of 15. Hope that helped!
The king size chocolate bar is three times as long as the regular bar, so given that the regular bar is 5 4/9 inches long, the king size bar is 16 1/3 inches long.
Explanation:The problem involves a regular size chocolate bar that is 5 4/9 inches long and a king size bar that is three times as long. Given the length of the regular bar, our objective is to find out how long the king size bar is.
We start by converting the mixed number 5 4/9 into an improper fraction which gives us 49/9 inches. We then multiply 49/9 by 3 to get the length of the king size bar which is 147/9 inches. Converting this improper fraction back into a mixed number, we get 16 1/3 inches. Therefore, the king size bar is 16 1/3 inches long.

C for question 1 A for question 2Step-by-step explanation:
First Question
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.
So what you want is something like 1.3 * e^-0.76 = 0.67
So which question is configured that way?
It's either C or D. but which one? It cannot be D. 0.38 is far too big: it does not represent 3.8%
C does represent 3.8% as a decimal. It is the correct answer.

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.
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]

Rearrange the equation so X is the independent variable. 6x+y=4x+11
Y=______________
6x+y=4x+11
y=4x+11-6x
y=-2x+11
[tex]\(y = 11 - 2x\)[/tex] is the rearranged equation with [tex]\(x\)[/tex] as the independent variable.
To rearrange the equation [tex]\(6x + y = 4x + 11\)[/tex] so that (x\) is the independent variable and (y) is dependent, we need to isolate (y) on one side of the equation.
Start with the given equation: [tex]\(6x + y = 4x + 11\)[/tex].
Subtract (4x) from both sides to move all terms involving (y) to one side: [tex]\(6x - 4x + y = 11\).[/tex]
Simplify the left side by combining like terms: 2x + y = 11.
To isolate y, subtract 2x from both sides: 2x + y - 2x = 11 - 2x.
Simplify: [tex]\(y = 11 - 2x\)[/tex].
So, the rearranged equation with (x) as the independent variable is y = 11 - 2x.
Detailed calculation:
Starting equation: (6x + y = 4x + 11)
Subtract (4x) from both sides:
[tex]\(6x - 4x + y = 4x - 4x + 11\)[/tex]
[tex]\(2x + y = 11\)[/tex]
Subtract (2x) from both sides:
[tex]\(2x + y - 2x = 11 - 2x\)[/tex]
[tex]\(y = 11 - 2x\)[/tex]
Therefore, [tex]\(y = 11 - 2x\)[/tex] is the rearranged equation with [tex]\(x\)[/tex] as the independent variable.

Step-by-step explanation:
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?
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]
