F(x)= 2x-5 and g(x)= x+3
write the expression for (f+g)(x) and simplify

f (x) = x + 2b + c, where the variable is "x". ... To evaluate a function, substitute the input (the given number or expression) for the function's variable (place holder, x).

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
