The steps to finding the inverse is writting:
- y = x + 5
- x = y + 5 (applying a change of variables).
- y = x - 5 (isolating y).
<h3>How to write the inverse of the given function?</h3>
Here we have the function:
y = f(x) = x + 5
Basically, to find the inverse we need to isolate x. The first step is writing
y = x + 5
Now let's do a <em>"false change of variables"</em> of x by y, so we get:
x = y + 5
Now we need to isolate y again:
y = x - 5
This is the inverse of the function f(x), we have:

All right angle triangles have a 90 degree angle. 90+42=132
All triangles have angles that add up to 180 degrees 180-132=48
90+42=132
180-132=48

Answer:
-1/4x + 1 ( If this is wrong then ignore this)
Step-by-step explanation:
The formula for a problem like this is y - y1 = m(x - x1). The x coordinate, -8 is the x1 and the y coordinate 3 is x1. So the equation is y - 3 = -1/4(x + 8)
Equation:
y - 3 = -1/4(x + 8)
y - 3= -1/4x - 2
y = -1/4x + 1
Therefore the equation for the line is y = -1/4x + 1
