Answer:
f^(-1)(x) = \frac{-1}{5} (x+4)
Step-by-step explanation:
Given is a function
To find its inverse.
We must check whether f is one to one or onto first
If -5x1-4 = -5x2-4 we get x1=x2
Hence f is one to one
Also for every f(x) we can find a x so f is onto.
So inverse exists
Let
Replace x by f inverse and y by x

Answer:
x=-2
Step-by-step explanation:
x-27 = 7x -15
subtract x from both sides
-27=6x-15
add 15 to both sides
-12=6x
divide both sides by 6
-2=x
x=-2
Answer:
The answer is -1/2
Step-by-step explanation:
We first start by removing x in order isolate the y variable
2y = 6 - x
y = 
Further, we simplify the equation in order to get the value of m (slope)
y = 3 + 
Therefore, our slope is equivalent to -1/2
