Question

Y varies inversely as x. y=3 when x=10. Use the variation constant and inverse variation equation to find y when x=6.

Do not type y= in your answer.

Answer 1

5

Explanation:

Given :

Y α 1/x

Y = k/x

Where, k = constant of proportionality ;

y = 3 ; x = 10

3 = k / 10

k = 10 * 3

k = 30

Equation becomes :

Y = 30/x

Y =? ; when x = 6

Y = 30 / 6

Y = 5
