Question

Which equation can be simplified to find the inverse of y=2x-7 ?

A.

`x = y {}^(2) - (1)/(7)`
B.

`(1)/(x) = {y}^(2) - 7`
C.

`x = {y}^(2) - 7`
D.

`- x = {y}^(2) - 7`
​

Answer 1

y = 2x - 7

Inverse:

x = 2y - 7

x + 7 = 2y

(x + 7)/2 = y

Answer: y = x/2 + 7/2

Answer 2

Answer with explanation:

The given Linear equation is:

y=2 x -7

→2 x= y +7

`x=(y+7)/(2)`

Replacing , x by ,y and y by x to get inverse of the given function

`y=(x+7)/(2)`

2 y = x +7→→Inverse of the function, y= 2 x -7

→None of the Option Matches with the given options.
