If we assume a constant inverse relationship then we can start with the equation y = c/x where c is the constant of proportionality. Plugging in the known values of x = 7 and y = 5 we determine that c = 35. We now have the equation of y = 35/x. Plugging in 4 for x we see that y = 35/4 = 8.75.

What is it when Z varies directly with x and inversely with y When x 2 and y 4 z 3 What is the value of z when x 4 and y 9?
z = 8/3.
If y varies directly with x and y equals 10 when x equals 5 what is the value of k?
We write y=kx since y varies directly as x. Now we know if x is 5, y is 10. so we write 10=5k so k=2

If y varies inversely as x and y equals 12 when x equals 6 what is k the variation constant?
If y and x are related inversely, then the equation for y can be said to be:y = k/xTo 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/x12 = k/612 X 6 = k72 = kThe value of the variation constant k is 72.
What is it when Z varies directly with x and inversely with y When x 2 and y 4 z 3 What is the value of z when x 4 and y 9?
z = 8/3.
If y varies inversely as the square of x and y equals 5 when x equals 2.5 what is the value of y when x equals 9?
So 5 = (xy)^2 and x = 2.5. This means that 5 = (2.5y)^2. So sqrt(5)/2.5 = y when x = 2.5. Now if x = 9 then 5 = (9y)^2. So sqrt(5)/9 = y. This means that for any x in this relation y = sqrt(5)/x.

What is the expression which connects y and x when y is inversely proportional to x and x equals 9 y equals 7. and what is the value of y when x equals 21?
x*y = k where k is a constant.When x = 9, y = 7 so k = 9*7 = 63 When x = 21, 21*y = 63 so y = 3.

How do you apply inverse variation to problems?
If one value of a variable increases as another value of a different variable decreases in a mathematical equation, they are said to be inversely proportional or vary inversely. For example, the strength of the force of gravity decreases as the square of the interacting distance increases, so the strength of gravity is inversely proportional to the square of the distance, or strength ∝ 1/distance2.
