Answer:
g = ±2h
Step-by-step explanation:
4g^2 -1= 16h^2 -1
Add 1 to each side
4g^2 -1+1= 16h^2 -1+1
4g^2 = 16h^2
Divide each side by 4
4/4g^2 = 16/4h^2
g^2 = 4 h^2
Take the square root of each side
sqrt(g^2) = ±sqrt(4h^2)
g = ±sqrt(4h^2)
g = ±2h
Answer:
-12
Step-by-step explanation:
What you have to do is plug -4 into the function as a puzzle. So, replace all x with -4.
f(-4) = 7(-4) - 4(-4) = -28 + 16 = -12
