1. Fireworks are to be launched from a platform at the base of a hill. Using the top of the platform as the origin and taking some measurements, it was determined that the cross-section of the slope of one side of the hill is y=4x-12 . If the path of the fireworks is y= -x^2+15x, calculate the point where the fireworks will land on the hill. (Show your work - 3 marks)

2. The solution(s) to the system of equations y=x^2-4 and y= 2x-4 is (are) ______.

#1 just solve for x in

4x-12 = -x^2+15x
Then you can get y.

#2 same thing. Just solve

x^2-4 = 2x-4
to get x, then you can evaluate y.
