Given g(x)=−2.5x+5 , what is g(−4)

g(-4) = 15

Plug in -4 into the equation for x.

g(-4) = 15

Step-by-step explanation:

g(x)=−2.5x+5

g(-4) = -2.5(-4) + 5

g(-4) = 10 + 5

g(-4) = 15

b.an increase in a causes b to decrease

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
