The graph below shows a system of equations:
draw a line labeled 2 y equals minus x minus 1 by joining the ordered pairs negative 3,1 and 3, negative 2. draw a line labeled 2 y equals x plus 5 by joining the ordered pairs negative 3, 1 and 3, 4. the x-coordinate of the solution to the system of equations is

Which one is true about the hexagons ?

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

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2
