O B. (fog)(x) = f(g(x))
O c. (f. g)(x) = f(x) g(x)
OD. (f+g)(x) = f(x) + g(x)

the answer is vanilla

step-by-step explanation:

f

step-by-step explanation:

f

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

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
