- Therfore sin theta >0

Answer:
Slope=0
Step-by-step explanation:
Y = -3x + b
Plug in point
-4 = -3(3) + b
-4 = -9 + b, b = 5
Solution: y = -3x + 5
Both can be right because if the function goes up, turns and goes down, between x = -2 and x = 2, it can happen that f(-2) = f(2) and then the average rate of change is [f(2) - f(-2)] / [2-(-2)] which is 0/4 = 0.
Answer:
D. 10 < x < 43
Step-by-step explanation:
4x+8 must be greater than 48, but less than 180.
48 < 4x + 8 < 180
40 < 4x < 172
10 < x < 43
