Question

Y varies inversely with x k=1.4 what is the value of x when y is 2

Answer 1

x = 0.7

Explanation:

given y varies inversely with x then the equation relating them is

y =
`(k)/(x)` =
`(1.4)/(x)`

when y = 2, then

2 =
`(1.4)/(x)` ( multiply both sides by x )

2x = 1.4 ( divide both sides by 2 )

x = 0.7
