2 cant help you there.

Step-by-step explanation:

9514 1404 393

Step-by-step explanation:

1. Substitute for k(x) and solve.

  k(x) = 6x -12

  15 = 6x -12 . . . . substitute for k(x)

  27 = 6x . . . . . . add 12

  27/6 = x = 9/2 = 4 1/2 . . . . . divide by 6

2. Find f(x) = 7 on the vertical scale. Follow that horizontal line over to the graph. Follow the vertical line at that intersection down to the x-axis. It will be halfway between the lines marked 4 and 6. That is, the x-value is 5.

  f(x) = 7 = f(5)

  x = 5
