Answer:
(f o g)(x) = -2x² - x + 4
Step-by-step explanation:
f(x) = -x + 6
g(x) = 2x² + x + 2
To find (f o g)(x), you need put g(x) into f(x).
f(x) = -x + 6
(f o g)(x) = -(2x² + x + 2) + 6
(f o g)(x) = -2x² - x - 2 + 6
(f o g)(x) = -2x² - x + 4
Answer:
D
Step-by-step explanation:
Supplementary angles sum to 180°
Subtract the given angle from 180 for the supplement, that is
180° - 89° = 91° ← the supplementary angle
2x - 20 = x + 15
x = 35
Now plug x in:
2*35 - 20 = 50 degrees
