Answer:
8
Step-by-step explanation:
f(x) = 5(3) - 7
f(x) = 15 - 7
f(x) = 8
To do this we need to rearrange the equation.
m = -8j - 9k + 9
Subtract (-8j + 9) from both sides
m + 8j - 9 = -9k
Divide both sides by -9
(m + 8j - 9)/-9 = k
The answer is C
Answer:
f(g(-4)) = 13.
g(f(-4)) = -3.
Step-by-step explanation:
g(-4) = (-4)^2 + 3(-4) - 1
= 3.
so f(g(-4))
= f(3)
= 2(3) + 7
= 13.
f(-4) = 2(-4) + 7
= -1.
so g (f(-4))
= g(-1)
= (-1)^2 - 3 - 1
= -3.
This is much easier to explain with a picture so...
First, simplify the coefficients. Then, simplify the variables. The y's cancel each other out so, you have your answer of -3x
