Write a T or F for the following statements. The constant of variation, k, is the value of yx .
The graph is non-proportional is it passes through the origin.
The graph is linear because y is positive. x
k, the constant of proportionality, is always same as the Rate of Change. To find the value of k, divide the given y-value by the given x-value. y = 5x − 1 is an example of linear equation.
We can use the equation y = kx to find the coeffient.
The graph of y = kx is linear and includes the origin (0, 0)

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)

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
