If square root x = -7, then x= -49 true or false

The height of a flare fired from the deck of a ship in distress can be modeled by h(t)= -2(8t^2-52t-28), where h is the height of the flare above water and t is the time in seconds. a. find the time it takes the flare to hit the water.

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1
