19 A rocket is launched from the ground and follows a parabolic path represented by the equation y = −x2 + 10x . At the same time, a flare is launched from a height of 10 feet and follows a straight path represented by the equation y = −x + 10. Using the accompanying set of axes, graph the equations that represent the paths of the rocket and the flare, and find the coordinates of the point or points where the paths intersect.
