Answer:
x = 0.25
Step-by-step explanation:
If y varies inversely with x, then:
![y \propto \dfrac{1}{x} \implies y=\dfrac{k}{x} \quad \textsf{(for some constant k)}](https://tex.z-dn.net/?f=y%20%5Cpropto%20%5Cdfrac%7B1%7D%7Bx%7D%20%5Cimplies%20y%3D%5Cdfrac%7Bk%7D%7Bx%7D%20%5Cquad%20%5Ctextsf%7B%28for%20some%20constant%20k%29%7D)
Given:
Substitute the given values into the found equation and solve for k:
![\implies 1.6=\dfrac{k}{0.5}](https://tex.z-dn.net/?f=%5Cimplies%201.6%3D%5Cdfrac%7Bk%7D%7B0.5%7D)
![\implies k=1.6(0.5)](https://tex.z-dn.net/?f=%5Cimplies%20k%3D1.6%280.5%29)
![\implies k=0.8](https://tex.z-dn.net/?f=%5Cimplies%20k%3D0.8)
Therefore:
![y=\dfrac{0.8}{x}](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B0.8%7D%7Bx%7D)
To find the value of x when y = 3.2, substitute y = 3.2 into the found equation and solve for x:
![\implies 3.2=\dfrac{0.8}{x}](https://tex.z-dn.net/?f=%5Cimplies%203.2%3D%5Cdfrac%7B0.8%7D%7Bx%7D)
![\implies x=\dfrac{0.8}{3.2}](https://tex.z-dn.net/?f=%5Cimplies%20x%3D%5Cdfrac%7B0.8%7D%7B3.2%7D)
![\implies x=0.25](https://tex.z-dn.net/?f=%5Cimplies%20x%3D0.25)
