The equations representing inverse variation are: pv = 13 and z = (2 / x) , option B and C are the answer.
What is an Inverse Variation ?
When on increasing one quantity the other quantity decreases , such variation between the two entities is called Inverse Variation
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.
The equations are given in the question and it has to be checked if they represent inverse variation
y = 2x
y and x are in a direct variation
pv = 13
p = 13 / v
P and v are represent an inverse variation.
z = (2 / x)
z and x are represent an inverse variation.
4 = v/x
v =4x
v and x are in direct variation
h=9g/5
h and g are in direct variation
therefore , the equations representing inverse variation are:
pv = 13 and z = (2 / x)
