Answer:

f(-5)= 90, g(7)= -3x+4

Step-by-step explanation:

First Solve f(x)

f(x)= 3×^2-3x

Plug in -5 to the x

3(5)^2-3(-5)

f(x)= 90

Then Solve g(x)

g(x)=-3x+4

Plug in the 7 in the x

g(x)=-3x+4

g(x)=17

Solve the following equation-<br> p-4=(-9)+p
Mashcka [7]
Simplifying p + -4 = (-9) + p
Reorder the terms: -4 + p = (-9) + p -4 + p = -9 + p
Add '-1p' to each side of the equation. -4 + p + -1p = -9 + p + -1p
Combine like terms: p + -1p = 0 -4 + 0 = -9 + p + -1p -4 = -9 + p + -1p
Combine like terms: p + -1p = 0 -4 = -9 + 0 -4 = -9
Solving -4 = -9
