Answer:
x=5
Step-by-step explanation:
I did math and ForGOt
Question 1:
For this case we have an equation of the form:

Where,
- <em>k: inverse variation constant.
</em>
Then, substituting values we have:

From here, we clear the value of k.
We have then:

Answer:
the constant of inverse variation is:

Question 2:
For this case we have:

Where,
- <em>k: constant of variation.
</em>
Then, substituting the value of the constant we have:

We now substitute the value of x:

Answer:
the value of y when x = 4 is:
