If f(x)=2x+3 and g(x)=x-3, what is g(f(

g(f(x))= 2x

Step-by-step explanation:

So g(f(x)) means that you are replacing the x value with the function f(X).

It will end up looking like this:

g(f(x))= (2x+3) - 3

Simplify

g(f(x))= 2x

Hope that helps!

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

i think it would be 42cm
