Which of the following points lies on the line x-3y=8 a. (2,4) b. (-1,-3) c. (-2,2) d. (-8,0)

Replace X and Y in the equation with the possible answers. If the equation works then that is the correct

Equation: x - 3y = 8

A) (2,4)

2-3(4) = 2-12 = -10, this does not equal 8 so is not correct.

B) (-1,-3)

-1 - 3(-3) = -1 + 9 = 8, This works correctly, therefore is the correct answer.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
