The value of the number can be equal to or less than -3
Answer:
3.8 seconds
Step-by-step explanation:
Given equation

When the ball hits the ground then height is 0
So we replace h with 0 and solve for t

a= -16 , b= 60 and c= 5
Apply quadratic formula to solve for t

=![\frac{-60+\sqrt{60^2-4\left(-16\right)\cdot \:5}}{2\left(-16\right)}[/tex[tex]=\frac{-60+-\sqrt{3920}}{-32}](https://tex.z-dn.net/?f=%5Cfrac%7B-60%2B%5Csqrt%7B60%5E2-4%5Cleft%28-16%5Cright%29%5Ccdot%20%5C%3A5%7D%7D%7B2%5Cleft%28-16%5Cright%29%7D%5B%2Ftex%3C%2Fp%3E%3Cp%3E%5Btex%5D%3D%5Cfrac%7B-60%2B-%5Csqrt%7B3920%7D%7D%7B-32%7D)



Now make two fractions and solve for x
t=
=-0.0815
t=
=3.83
So answer is 3.8 seconds
7x+9 equal 10 because it is equal to 5,
