To find the inverse, switch the x and y, and then solve for y (f(x) is the same as y)
So we get:
x=1.50y-30 (add 30 to both sides)
x+30=1.50y (divide both sides by 1.5)
x/1.5+30/1.5=y
y=x/1.5+20
Hope this helps
Add them all together and there is your sum
First is -1 and 4, second should be no solution and the third is 2 and 6
In order they make 20$/hr, 5$/h, 10$/hr, and 30$/hr. The last one makes the most by far!
