5. The height, h, of a baseball, in feet, at a time of t seconds after it is tossed out a 2M story window is modelled by h(t) = -5t? + 20+ + 15. A boy shoots at the baseball with a
paintball gun while standing in the 3rd story window. The trajectory of the paintball is
given by the equation h(t) = -3t+15. Will the paintball hit the baseball? If so, when
and at what height?

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
