Best ResponseYou've already chosen the best response.1Or, equivalently, it can be expressed as\[y = \dfrac{k}{x}\]

Best ResponseYou've already chosen the best response.1\[k = yx\]Here, we can plug the values \(y = 6\) and \(x = 8\). What do you think?

Best ResponseYou've already chosen the best response.1I'd give you an example. There's an inverse relation and when \(y = 4\), \(x = 6\). The general equation would be \(k = yx\). find out \(k\), the product of all \(y\)s and the corresponding \(x\)'s.

Best ResponseYou've already chosen the best response.1So the general equation for my example is \(k = 24\)

Best ResponseYou've already chosen the best response.1It's very easy. What's the product of the \(x\) and \(y\) you're given?
