If the input, x, is 16, which equation results when output of 4? a) y = x(squared)

b) y = x + 12

c) y = x - 20

d) y = x - 12

d) y = x-12

Step-by-step explanation:

x is the input

y is the output

d) 4 = 16 - 12

step-by-step explanation:

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)
