Triangle xyz has vertices x(6, -2.3), y(7.5, 5), and z(8, 4). when translated, x' has coordinates (2.8, -1.3). write a rule to describe this transformation. then find the coordinates of y' and z'.

Solve the given system of equations. 2y= -x+9 , 3x-6= -15

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
