Some students used a water balloon launcher to launch a water balloon from the top of a building. The function gives the height h (in feet) of a water balloon after t seconds. How long is the water balloon in the air before it hits the ground?

h=16t^2+48t+64

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
