Harriet believes that the function y=11x is linear, while Paul believes that it’s not. Who is right and why

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

How do the number line graphs of the solutions sets of -23 > x and x-23 differ?
