PLEASE HELP ME ITS MULTIPLE CHOICE

Do, h = (7, 9) (14, 18) the scale factor is

If f(x) and g(x) are inverse functions of each other, which of the following shows the graph of f(g(x)

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
