Answer:

see below

Step-by-step explanation:

(w+14)/2 = 10

w+14 = 20

Subtract 14 from each side

w+14-14 = 20-14

w = 6

Using f(x) = 2x + 7 and g(x) = x - 3, find f(g(x)).

Eva8 [605]

Answer:

2x+1

Step-by-step explanation:

that's a hard question

we know that g(x)= x-3

so f(g(x))= f(x-3)

we put it in the equation :

f(x-3)= 2(x-3) +7 = 2x-6+7 = 2x +1
