If f(x) = x^2 and h(x) = 2-x, then hf (-3) =

hf(-3) = -7

Step-by-step explanation:

f(x) = x²

h(x) = 2 - x

To find hf(x), we will substitute f(x) function as x into the h(x) function.

h(x) = 2 - x

hf(x) = 2 - (x)²

hf(x) = 2 - x²

How that we have the hf(x) function, to find hf(-3), we substitute x = -3 into the new function.

hf(x) = 2 - x²

hf(-3) = 2 - (-3)² = 2 - 9 = -7

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
