Here's my question:
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 crosssection of the slope of one side of the hill is y=4x12 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)
Here's my work on the question:
x^2+15x=4x12
x^21112=0
(x12)(x+1)=0
It needs to be coordinate and can you please show your work for getting the answer,
Thanks you1
