To find the inverse of a function, replace x and y in the equation and solve for y. In our case...

x=2y-10
x+10=2y
y=x/2+5

How do you solve for x
larisa [96]
Well, <T+<S will equal 11x +2 
so the equation will be 5x+10 + 58 = 11x +2
5x + 68 = 11x +2
66 = 6x (subtract 2, subtract 5x)
x = 11 (division)

To check,
<T = 5 (11) +10
<T = 65
11(11)+2 = 123
<T+<S = 123
65+58 = 123

What mixed number does it show?
Gelneren [198K]
Hi there!

Since there are 4 columns of boxes fully shaded in and one other box with one section shaded in out of 6 sections, the answer would be
4 + 1 of 6, or

4 1/6.

Hope this helps!
