Okay so I'm in Advanced functions and Modeling in math in an online class and it's really stressing me out. So if you answer me

you will have to be patient so i can learn because i'm not the best at math.
Okay so- Given: f(x) = x - 7 and h(x) = 2x + 3

Write the rule for h(f(x)). I do not know how to do this and i'm in one classroom all day with someone who doesn't know math so... help?

You start from in to out, so in the case of h (f (x)) we start by substituting f (x)

By substituting f (x) you get h (x-7)
Now substitute x-7 in x's in the function h (x)
2x+3 will be 2 (x-7)+3
Therefore, h (f (x)) is 2x-14+3 which is 2x-11

igomit [66]
Let’s remember the most basic thing in percentages, the equation.

Percent x Whole = Part.

We know the whole, and the part, but we are trying to find the percent, so we have to divide the two, first turn your whole and part into a decimal.

Percent x 0.4 = 0.18, so we divide 0.18 by 0.4

0.18/0.4 = 0.45

0.45 = 45%
