A system for tracking ships indicated that a ship lies on a hyperbolic path described by 5x^2 - y^2 = 20. The process is repeated and the ship is found to lie on a hyperbolic path described by y^2 - 2x^2 = 7. If it is known that the ship is located in the first quadrant of the coordinate system, determine its exact location.

Option A, and option C would be the solution, but since the question states that It lies in the 1st quadrant, both values must be positive. The only 2 values that are positive would be option C.
