Answer:1(1+1)(1+2)(1+3)
Step-by-step explanation:
The answer is
<span>D. y = 4cos(-x) - 2
proof
cosine is an even function, it means cos(-x) = cosx
so </span>y = 4cos(-x) - 2 = y = 4cos(x) - 2
N = -9
8(-7+n) = -128
Divide both sides by 8
-7 + n = -16
Add 7 to both sides
n = -9
33+15 = 48 hope that helps
