x
Answer: 33
Step-by-step explanation:
(f of g)(2) = f(g(2))
g(2) = -2(2) = -4
f(-4) = (-4)^2 - 3(-4) + 5 =
16 - - 12 + 5 =
16 + 17 =
33
Answer:
x=5 and 3
Step-by-step explanation:

x^2-8x+21+16=6+16
(x-4)^2=1
(x-4)=±1, x=5 and 3

Answer:
the slope is -3/2
Step-by-step explanation:
We need to get the equation in the form
y = mx +b where m is the slope and b is the y intercept
6x+6 = -4y
Divide by -4
-6x/-4 +6/-4 = -4y/-4
-3/2 x -3/2 = y
The slope is -3/2 and the y intercept is -3/2
