Answer:
Step-by-step explanation:
hello :
a)
let f(x) = y so : x = g(y)
in expression = f(x) =3x+12
means : y = 3x +12 calculate : x
3x = y -12
x = (1/3)y - 4
the inverse is : g(x) = (1/3)x - 4
b)f(g(-2) = f(-14/3)
because: g(-2) = (1/3)(-2)-4 = -2/3-4 = -14/3
so : f(g(-2) = f(-14/3)=3(-14/3)+12 = - 2

Answer:
books per hour.
Step-by-step explanation:
Given:
For
hours, part of book is 
To find: Unit rate
Unit rate is the part of book completed in one hour.
So, we use unitary method to determine the unit rate.
Unit rate is given as:

On dividing 2 fractions, the division changes to multiplication and the second fraction is reversed. This gives,

Therefore, the unit rate is
books per hour.
