Question

How do you write the equation if E is inversely proportional to Z and Z = 4 when E = 6?

Answer 1

If E is inversely proportional to Z
`color(white)("XXXXX")` `E*Z = c` for some constant `c`

Given `(E,Z) = (6,4)` is a solution to the desired relation
`color(white)("XXXXX")` `6*4 = c`
`color(white)("XXXXX")` `c= 24`

and the equation is
`color(white)("XXXXX")` `E*Z = 24`
