Look at the table of values below. x y 1 -1 2 -3 3 -5 4 -7 which equation is represented by the table? a. y = 1 − 2x b. y = -x − 1 c. y = x − 2 d. y = 2x − 1

A. y=1-2x

Step-by-step explanation:

if to substitute the values of 'x'=1; 2; 3; 4 into the equations, only the 'A' is correct.

(-1,-0.5)

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)
