Y Varies Inversely As X
Inverse means 1 variable. In other words the expression xy is constant.
Write An Inverse Variation Equation That Relates X And Y Assume
The reason is that y doesn t vary by the same proportion that x does because of the constant 24.
Y varies inversely as x. For x 1 2 and 3 y is 7 1 3 8 2 3 and 10. 8 k 4 k 4 8 32. This can be done with the help of the given information that x 2 when y 8.
We need to determine the value of k. The k is called the proportionality constant. That is y varies inversely as x if there is some nonzero constant k such that x y k or y k x where x 0 y 0.
To find k use the given condition that y 8 when x 4. Y varies inversely as x and y 4 when x 15 solve for y when x 34. Let k represent the constant defining this inverse porportion k 100 2 50 k 50.
Notice that as x doubles and triples y does not do the same because of the constant 6. Where k is the constant of variation. Y k x.
An inverse variation can be represented by the equation x y k or y k x. If y varies inversely as x find the constant of variation k and the inverse variation equation for the situation. Equation is 2 2y 32 x 2 2.
X varies inversely upsidedownwardly as y which really means that if y goes up then x goes down and vice versa. The statement is expressed as y 1 x. To convert to an equation introduce k the constant of variation.
As the value of x decreases y increases and vice verse as they vary inversely. In your equation y 4x 3 6 for x 1 2 and 3 you get y 4 2 3 3 1 3 and 2. The statement y varies inversely as x means that when x increases ydecreases by the same factor.
X 16 y 32 16. Y k 1 x. Where k is the constant of variation.
We can also express the relationship between x and y as. If x varies inversely as y 2 and x 2 when y 10 find x when y 2.
