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.

Answer:

equations represented inverse variation are:

pv = 13

z = (2 / x)

When a number is tripled,the results is -33

defon

Answer:

x = -11

Step-by-step explanation:

Considering tripled means multiplied by 3 because of tri, we know that we can use the equation 3x = -33.

To solve this we can divide both sides by 3:

3x = -33

x = -11

This gives our answer of -11.
