A seagull is flying upwards such that it's height h in feet above the sea is given by h=3t. At the same time, the height h in feet of a rock falling off a cliff above the sea after t seconds is given by h=-16+50. Find the approximate time it takes for the rock and the bird to be at the same height.

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.
