If John can repair one machine every 2 hours, write a function h(n) for the hours needed to repair n machines.

If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (cxd)(x)

When only separate discreet points are graphed it is called?

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
