Question

Find the value of x so that the function has the given value.

k(x)=6x−1/2; k(x)=18

Answer 1

x =
`(37)/(12)`

Explanation:

Given k(x) = 6x -
`(1)/(2)` and k(x) = 18, the equate the right sides, that is

6x -
`(1)/(2)` = 18 ( multiply through by 2 to clear the fraction )

12x - 1 = 36 ( add 1 to both sides )

12x = 37 ( divide both sides by 12 )

x =
`(37)/(12)`
