Answer:
- f(g(2)) = 14
- g(f(-2)) = 91
Step-by-step explanation:
g(2) = 4(2^2) -9 = 4(4) -9 = 7
f(7) = 7+7 = 14
f(g(2)) = 14
__
f(-2) = -2 +7 = 5
g(5) = 4(5^2) -9 = 4(25) -9 = 91
g(f(-2)) = 91
Answer:
<h2>x = 45°</h2>
Step-by-step explanation:
If AC is a supplementary line, then
x + 90° + x = 180°
solution:
2x + 90° = 180° |<em>subtract 90° from both sides</em>
2x = 90° |<em>divide both sides by 2</em>
x = 45°
