Answer:
The inverse of a given function
d) 
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that f(x) = 4x + 12
let y = 4 x + 12
4 x = y - 12

we know that y = f(x)
⇒ x = f⁻¹(y)

Put replace 'y' in 'x'

<u><em>Final answer</em></u><em>:-</em>
The inverse of a given function

Answer: see below...
Step-by-step explanation:
a)
48 = 30%
100/30 = 10/3
48 x (10/3) = 160
$160 = 100%
b)
160 - 48 = $112
Answer: 4x
Step-by-step explanation:
Formula: a^2+2ab+b^2.
So in this case our a^2 is x^2. our b^2 is 4.
To find the middle term (2ab) we do 2*x*2 = 4x
