Given the statement:
For the inverse variation equation xy = k
Determine the constant of variation when = 7
y = 3
Solution:
In order to determine the constant of variation k, we simply need to equate the values into the equation k = xy
k = xy
k = (7)(3)
k = 21
Final answer:
The constant of variation is 21.
