Write the inverse variation equation for z and w if w varies inversely with z, and w=3/10 when z=−5/9

Answer 1

An inverse variation is shown as follows:

y = k/x where k is a constant

In this case w varies inversely with z so we would write:

w = k/z

We can then plug in the given numbers to our equation:

3/10 = k / -5/9

Those are the two equations that show the relationships from the problem
