Answer:

x = -9

Step-by-step explanation:

x = -y/4

y = -2(-y/4) + 18

y = y/2 + 18

y/2 = 18

y = 36

x = -36/4

x = -9

If g (x) = 3x²-4, then find g (-3)
Semenov [28]

Answer:

g(-3) = 23

Step-by-step explanation:

This question is telling us that x = -3. Knowing this, we can plug x into the equation and solve to find g(-3).

g(-3) = 3(-3)^{2} -4

g(-3) =3(9)-4                      Square -3 to get 9

g(-3) = 27-4                         Multiply 9 by 3 to get 27

g(-3) = 23                               Subtract 4 from 27 to get 23

Thus, g(-3) is equal to 23.

I hope this helps! Good luck!
