Answer:
A 18
Step-by-step explanation:
f(x) = 4x + 10
f(2) = 4(2) + 10
f(2) = 8 + 10
f(2) = 18
The answer is D (- 4x^2 - 3x - 5)
Explanation:
- 4f(x) - 3g(x)
= - 4(x^2 + 5) - 3(x - 5)
= - 4x^2 - 20 - 3x + 15
= - 4x^2 - 3x - 5

Answer:
x=(-1/2) y=(3/2)
Step-by-step explanation:
y=x+2 Given
-3x=x+2 Substitute (-3x) for y
-2-3x=x Subtract 2 from both sides
-2=4x Add 3x to both sides
(-1/2)=x Divide both sides by 4.
y=x+2 Given
y=(-1/2)+2 Substitute (-1/2) for x
y=1 1/2
or
y=3/2
