X2 + y2 = 1 x = 1 Hina's work: substitute: (1)2 + y2 = 1 simplify: 12 + y2 = 1 isolate the variable: y2 = 0 solve for y: y = 0 Complete Hina's work to determine which statements are true for the system of equations. Check all that apply. The system of equations has no solutions. The system of equations has one solution. The system of equations has two real-number solutions. A solution to the system is (0, 0). A solution to the system is (1, 0).
