The list of ordered pairs below represents a function (12, 6), (3, 1), (2,-2), (5, 10), (-8, -4) (_,_)

Which of the following could be the missing ordered pair?
A. (2,1)
B. (12,7)
C. (-8,8)
D. (-3,-4)

Step-by-step explanation:

Ordered pairs

Since it is a function, the missing pair can't repeat input values with different output, therefore only option D is unique so is the correct choice

because they could drop even lower..

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)
