A pet owner throws a tennis ball for his dog to chase. The tennis ball’s height in feet after it is thrown upward is given by –16x2 + 32x + 4, where x represents the time in seconds after the ball was thrown. After how many seconds will the ball hit the ground?

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
