Question

Need help I am stuck between 2 answers.
When x=2 and y=3, z=42. Write the function that models each of the following relationships.

z varies inversely with x and directly with y.
a. z=7xy << 13 years ago

Answer 1

The first sounds like the correct answer

Answer 2

I am thinking it is more a. because c. doesn't have z in the equation.

Answer 3

Because it is written as a relation of z,x,y

Answer 4

thank you for clearing that up for me
