If y and x are related inversely, then the equation for y can be said to be:
y = k/x
To find the constant k, substitute 12 for y and 6 for x (a pair of values that are known to satisfy the equation).
y = k/x
12 = k/6
12 X 6 = k
72 = k
The value of the variation constant k is 72.

A number y varies inversely as the square of x If y equals 2 when x equals 6 what is y when x equals 3?
x2y = k (constant) so 36 x 2 ie 72 is the constant. If x = 3 then y = 72/9 = 8
If y varies directly with x find the constant of variation if x equals 8 and y equals 12?
y = cx when x = 8, y = 12 so that 12 = 8c which gives c = 12/8 = 1.5
If y varies inversely as x and y equals 24 when x equals 8 find y when x is 4?
y is 12

What is the difference between direct variation and inverse variation?
Direct variation is the ratio of two variable is constant. Inverse variation is when the product of two variable is constant. For example, direct variation is y = kx and indirect variation would be y = k/x .

Complete the equation of variation where y varies inversely as x and y equals 4 when x equals 2?
xy = 8 or y = 8/x
F x varies directly with x and y equals -2 when x equals 8 Find the constant of variation k?
What is y? Fx varies with x, but y could be anything.
T varies directly as r and inversely as s t equals 2 when are equals 26 and s equals 78?
(direct variation) t = kr, where k is any constant, and it is called the constant of the variation.t = 2 when r = 26t = kr2 = k(26) (divide by 26 to both sides)2/26 = kk = 1/13(indirect variation) t = c/s, where c is any constant, and it is called the constant of the variation.t = 2 when s = 26t = c/s2 = c/78 (multiply by 78 to both sides)156 = c
Suppose y varies inversely with X use the information to find K and choose the equation of variation. X equals 7 and y equals 3?
xy = K so K = 21
Is x plus y equals 8 a inverse varition?
x+y=8 y=-x+8 is not an inverse variation. However, y=8/x is an inverse variation or y varies inversely as x.
Assume that y varies inversely with x and that y is 2 when x is 4 what is the equation of inverse variation?
2=8/4 the constant is 8 y-k/x i think.
