a(8x + 7) = 4x + 3.5

8ax + 7a = 4x + 3.5

equating coefficients of x : 8a = 4 so a = 1/2

also 7a = 3.5 so a = 1/2

The value of a is 1/2

Find f(g(-4)) if f(x) =7/x+2<br> and g(x) = (x + 5)^2. Options: -5/2 , -7/2 , 37/4 , 7/3

aev [14]

Answer:

7/3

Step-by-step explanation:

f(x) =7/(x+2)

g(x) = (x + 5)^2

f(g(-4))=

First find g(-4)

g(-4) = (-4+5)^2

=(1)^2 =1

Then find f(1)

f(1)= 7/(1+2)

= 7/3
