A system of equations has 1 solution. If 4x - y = 5 is one of the equations, which could be the other equation?
AN
y = 4x + 5
y = 4x - 5
2y = 8x - 10
-2y = -8x - 10

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
