Which system of equations could you use to determine where the paths intersect?

A
y = 0 and y = -0.12(x - 20)2
B
y = 0.8x and y = -0.12x2 + 20
C
y = 0.8x and y = -0.12(x - 20)2
D
y = 0.8x + 8 and y = -0.12x2 + 20

What can you conclude about the paths of the skaters?

A
There is no chance that the skaters will hit each other.
B
The skaters' paths cross each other at two different points on the rink.
C
The skaters are traveling on the same path, but possibly in different directions.
