If a ball is thrown upward at 96 feet per second from the top of a building that is 140 feet high, the height of the ball is given by S = 140 + 960 - 1612 feet
where t is the number of seconds after the ball is thrown. How long after it is thrown is the height 140 feet?
t =

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
