Step-by-step explanation:

When y varies jointly as x and z, the equation is written ...

  y = k·x·z

Here, the joint variation is not with z, but with z². There is also an inverse variation with w, so the entire relation is ...

  y = k·x·z²/w

We want to find the value of k for the given values of the variables. So, we can solve for k to get ...

Then the equation of variation is ...

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
