If you would like to know what do the f(x) and x represent in Luke's situation, you can find this using the following step:

<span>f(x) = 7x + 15
</span>7 hours each week
x ... the number of weeks
f(x) ... the total number of hours Luke exercises

The correct result would be A) <span>f(x) represents the total number of hours; x represents the number of weeks he exercises this summer.</span>

Simplify the expression and combine like terms.
Alenkinab [10]

Answer:

5x + 16

Step-by-step explanation:

the first thing you do in this equation is to distribute the 2 into x + 6

you get

2x + 12 + 3x + 4 = ?

then you must put the 2x and the 3x together

5x + 12 + 4

and you can then add the 12 and 4

5x + 16

Hi! Basically, the problem is asking us to find the values of a, b, and c in the equation f(x)=a x^{2} +bx+c. Since we have three unknowns, we just need three equations. We can find these equations by using the data in the table.

First let's plug x = 0 and f(x) = 0.
0=0+0+c
c=0

Now that we know c, it's time to pick two more pairs. Let's plug-in (2,78) and (4,152)

78=4a+2b
152=16a+4b

Before proceeding with the process of eliminating one variable, let us first reduce both equations to their lowest terms. We divide the first equation by 2 and we divide the second one by 4.

39=2a+b
38=4a+b

Next, we subtract equation 2 from equation 1.

1=-2a
a=-0.5

Finally, we substitute the value of a to equation 2 to get the value of b.

38=4(-0.5)+b
b=40

Therefore, the function should be f(x)=-0.5 x^{2} +40x
