f(x) = 2x + 8 --  f(5) = 2(5) + 8 = 10 + 8 = 18\\\\f(x) = 3x +4 --  f(8) = 3(8) + 4 = 24 + 4 = 28

Good day and hope that helps!

A)  f(5) = 3(5) + 4 = 19
b) f(-3) = 2(-3) - 8 = -14
c)  f(7) = 9(7) - 24 = 39

Substitute 5, -3, and 7 for x.

Step-by-step explanation:

f(x) = 2x + 4 and g(x) = 3x + 1,

find g(f(5))

f(5) = 2x+4  where x=5

     =2(5) +4

     = 10+4

     = 14

f(5) =14

The substitute x=14 into g(x)

g(x) = 3x+1

g(15) = 3(14) +1

          =42+1

            =43

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180
