F(x) = 5x + 7
and
g(x) = -2x - 4
Find
g(f(x)) = [ ? ]x + [?]

g(f(x)) = -10x - 18

Step-by-step explanation:

g(f(x)) = -2(5x + 7) - 4 > Replace the x in g(x) with the f(x) equation

g(f(x)) = -10x - 14 - 4

g(f(x)) = -10x - 18

Does that help?

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
