Use the information below to complete the problem: p(x) = (1)/(x + 1) and q(x) = (1)/(x - 1)
Perform the operation and show that it results in another rational expression.

p(x) * q(x)

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
