Answer:
f
−
1 (
x
) = x + 12
Step-by-step explanation:
To find the inverse, interchange the variables and solve for
y
.
I hope this helps.
For this case we have the following system of equations:

We multiply the first equation by -5:

Thus, we have the equivalent system:

We add the equations:

We find the value of the variable "x":

Thus, the solution of the system is:

Answer:

| -6x - 3 | > 15
This expression can be written as:
a) -6x - 3 > 15
b) -15 > - 6x - 3
Solving a part:
Solving b part:
or we can write:
x > 2
So the solution to given inequality is:

The second option correctly lists this solution.
