Answer: y=46

Step-by-step explanation:

Varies inversely means y=k/x, where k is a constant.

---------------------------------------------------------

First Step: find the constant [K] in the equation

y=k/x

23=k/8

k=184

Second Step: Apply the [k] to the second part of the question

y=k/x

y=184/4

y=46

Hope this helps!! :)
