Find the value of x so that f(x)= 13, given that f(x)= x-10.

f(x) = x - 10

13 = x - 10

13 + 10 = x

23 = x

So x  is 23

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
