F(x) = |x|; Find f(8)

8

Replace the x with 8.

The absolute value makes any number positive.

Since 8 is already positive, there is no change in the answer.

f(8) = 8

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
