Which equations represent inverse variation? check all that apply. y = 2x pv = 13 z = (2/x) 4 = (y/x) h = (9g/5)

For this case, what you should know is that the equations that represent an inverse variation are those that could not form a straight line, for example.

 We have then:
 Equation 1:
 pv = 13
 Rewriting:
 p = 13 / v
 P and v are represent an inverse variation.
 Equation 2:
 z = (2 / x)
 z and x are represent an inverse variation.
 
 equations represented inverse variation are:
 pv = 13
 z = (2 / x)

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b
