In a problem involving direct variation, a constant k can be determined using known values of x and y. This constant can then be used to find unknown values for these variables. In this case, the constant k = 2.5, and x = 5.6 when y = 14. ;
y = 10 an d x = 4 y = 14 an d x = ? M akin g r a t i o : 10 − 4 14 − x C ross m u lt i pl i c a t i o n : 10 x = 4 ∗ 14 10 x = 56 ∣ D i v i d e b y 10 x = 5 , 6 so l u t i o n i s x = 5 , 6.
The value of x when y = 14 is 5.6, found using the proportionality constant k from the initial values of x and y. The constant k was determined to be 2.5 by substituting the initial values into the direct variation equation. This relationship allows us to find the corresponding x value for any given y value through a simple equation.
