Step-by-step explanation:
The math club must sell 50 pies in order to reach the goal of 200 dollars
Answer:
B
Step-by-step explanation:
We see that the line intersects the y-axis at -1. As a result, we need to choose an equation with -1, either B or C. We see that the different is the slope. For choice B, the slope is
, meaning that every unit up equates to 3 blocks to the right. Counting along the line, we see that this is correct.
The answer is b
2cos x + 1 = 0
2 cos x = -1
cos x = -1/2
x = cos^1(-1/2)
(cos inverse (-1/2))
x = 120°
