Answer:
D
Step-by-step explanation:
first multiply both sides by 12
collect like terms
x/12×12+3×12<=7×12
x+36<=84
x<=84-36
x<=48
Answer:
The first one is D, and the second one is also D

Answer:

Step-by-step explanation:
Given the function

We can find the inverse function by exchanging x and y, and then solve for y.
