Answer:

C. Both (1, 11) and (-1, -5)

Step-by-step explanation:

The missing options are:

A. Only (1, 11)

B. Only (-1, -5)

C. Both (1, 11) and (-1, -5)

D. Neither

To check if an ordered pair is a solution of an equation, replace one variable into the equation an calculate the other one.

Replacing x = 1, we get:

y = 8(1) + 3

y = 11

then (1, 11) is a solution

Replacing x = -1, we get:

y = 8(-1) + 3

y = -5

then (-1, -5) is a solution

kompoz [17]

Answer:

D) -10

Step-by-step explanation:

We will assign g(x) to be equal to 25, and then solve for x:

25 = -3x-5

30 = -3x

10 = -x

-10 = x
