Answer:
![xy=72](https://tex.z-dn.net/?f=xy%3D72)
Step-by-step explanation:
If x is inversely porportionaly to y, then for some constant k,
![x = \frac{k}{y}\\xy=k](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7Bk%7D%7By%7D%5C%5Cxy%3Dk)
Since y is 4 when x = 18, k is equal to 4*18=72, so the equation is:
![xy=72](https://tex.z-dn.net/?f=xy%3D72)
