Answer:
3/1, or 3
Step-by-step explanation:
When you have a perpendicular line, if it is a negative, you take away the negative, and if it is a fraction, you turn it upside down. 1/3 becomes 3/1.
Hello there!
m = 10x - x, solve for x.
First, we need to combine like-terms.
10x - x = 9x.
We now have:
m = 9x
Divide both sides by 9 to solve for x.
x =

I hope this helps!

Answer:
It is the second
Step-by-step explanation:
f(x) = 1/9x + 2
To find the inverse, we need to do this:
Replace f(x) with y
y = 1/9x + 2
Replace x with y
x = 1/9y + 2
Solve for y
Subtract 2
x - 2 = 1/9y
Multiply by 9
9x - 18 = y
Replace y with f^-1(x)
f^-1(x) = 9x - 18
