We have that #y=k/x=>k=yx=>k=50#

To determine the constant of proportionality (k), we can use the formula for inverse proportionality: y = k/x.

Given that y = 10 when x = 5, we can substitute these values into the formula: 10 = k/5.

To solve for k, we can multiply both sides of the equation by 5: 10 * 5 = k.

Therefore, k = 50.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
