Two functions are shown below:

g(x) = 4x - 8

h(x) = 3x - 4

What is g(4) - h(2)?

• 5

• 6

• 8

• 9

• 2x - y = -1

• -2x + y = -1

• 2x - 2y = -1

• -x + y = 1/2

What is the correlation coefficient? Round to the nearest hundredth.

Let f(x) = -2x - 5. If f(x) = -25, find x.

If point S(4, 2) is the midpoint between points R and T, what is point R if the coordinates of T are (9, 17)?
