Question

assume that y varies directly with X write an equation relating X and Y also find the value of y when X is 18 y=6 when x=18

Answer 1

The condition is that y = 6 and x = 18 and the relation between x and y is directly, so it should be:

`y=(x)/(3)`

so if x = 18 then

`y=(x)/(3)=(18)/(3)=6`
