"Note how for each (x,y) pair of points given we see that x*y = 60
For instance, the point (4,15) has x = 4 and y = 15 so x*y = 4*15 = 60
Another example: (x,y) = (6,10) means x = 6 and y = 10, so x*y = 6*10 = 60
The fact that this is true for ALL of the points shown indicates we have an inverse variation of the form x*y = k where k = 60 in this case.
Therefore, the answer is B.) An inverse function is the best model because the products of corresponding x- and y-values are equal."

Answer:
8
Step-by-step explanation:
So you can start by simplifying each fraction:
16/6 divide by 2/2 = 8/3
3s/9 divided by 3/3 = s/3
Then, since 8/3 = s/3 you just have s = 8.
