Answer :

We have been told from the question that the relationship between y and x is a direct variation.

x varies directly with y

then the relationship will be

y= k x

where k is a constant

so we can obtain k since the values of x and y have been given

k = y/x

y = 20, x = 12

k = 20/12

k= 5/3

[tex]\begin{gathered} y\text{ = kx} \\ y\text{ = }\frac{5}{3}x \end{gathered}[/tex]

The relationship is 5/3x

Thanks for taking the time to read I am trying to figure out an equation that relates to x and y where y 20 and x 12. We hope the insights shared have been valuable and enhanced your understanding of the topic. Don�t hesitate to browse our website for more informative and engaging content!
