Answer:
D
Step-by-step explanation:
Suppose f(x)=6x-2 and g(x)= 2x+4
a.
(f+g) (x) = 6x - 2 + 2x + 4
(f+g) (x) = 8x + 2
b.
(f-g) (x) = 6x - 2 -( 2x + 4)
(f-g) (x) = 6x - 2 - 2x - 4
(f-g) (x) = 4x - 6
y = 4
-1y = -4
Divide both sides by -1 to get y by itself.
-1/-1 = -4/-1
It's positive because there are two negatives, which mean they cancel out.
Here you go.
STAY SAFE, GOD BLESS YOU :)
