5(2x-7)
= (5)(2x+-7)
= (5)(2x)+(5)(-7)
= 10x - 35
25 in total what do you mean
x adds 1 and y subtracts by 6
6b+2 I think I combined them and that’s what I got
For this case we have the following functions:

By definition of composition of functions we have to:
So:

By definition of division of powers of the same base we have to place the same base and subtract the exponents:

ANswer:
