What is the solution to the following system?
X+ 2y + Z = 9
%-Y+32 = 13
2z = 10
x = 10, y = 2, z = 5
x= -4, y = 2, z = 5
x = 0, y = 2, z = 5
x = 4, y = 6, z = 5

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

Lines a and b are parallel. what is the value of x? -5 -10 -35 -55
