Answer:
y=-30x+450
if she reads 30 pages every day it will take 15 days
<span>Divide both sides by 4 to get



So we can pick n to be 3 or it can be less than 3
Three values we can pick are: n = 0, n = 1, n = 2
Or we could pick: n = 1, n = 2, n = 3

-3x + 9 - 4 = x + 3 + 2x
-3x + 9 - 4 = 3x + 3
9 - 4 = 6x + 3
5 = 6x + 3
2 = 6x
1/3 = x
Answer:
9.9
Step-by-step explanation:
Put the values of x to the equations of the functions:
1. f(9) → x = 9; f(x) = -3x + 10
f(9) = -3(9) + 10 = -27 + 10 = -17
2. f(-2) → x = -2; f(x) = 4x - 1
f(-2) = 4(-2) - 1 = -8 - 1 = -9
3. f(-5) → x = -5; f(x) = -2x + 8
f(-5) = -2(-5) + 8 = 10 + 8 = 18
