Franklin's faucet was leaking, so he put a bucket underneath to catch the water. after a while, franklin started keeping track of how much water was in the bucket. his data is in the table below.

The path traveled by a bottlenose dolphin as it jumps out of water is modeled by the equation y=-0.4+3x, where t is the height above water and x is the horizontal distance in feet. if a beam of light is shone upward at an angle modeled by the equation x+y=10, at what height from the waters surface will the beam of light hit the dolphin
