A skydiver parachutes to the ground. The height y (in feet) of the skydiver after x seconds is y=-10x+3000. If the skydiver lands on land on the ground after 300 seconds what is the x-intercept

Respuesta :

put y=0 & find x. call it x1.

put x=0 & find y. call it y1.

define the points (x1, 0) & (0, y1) on a cartesian plane. connect the points with a line to find the interception.
