Question

The variables x and y represent nonzero rational numbers. Which situation could be solved using the product of xy, where xy represents a negative value? the depth of a scuba diver if he dives x feet below sea level and then rises y feet the amount of juice Susan drinks in x days if she drinks y fluid ounces of juice each day the change in degrees if the temperature decreases by x degrees per day for y days the change in the price of an item if the price is increased by x dollars one month and decreased by y dollars the next month

Answer 1

if the temperature decreases by x degrees per day for y days

Explanation:

A rational number is a number of the form
`(p)/(q)\,,q\\eq 0` such that p and q are integers.

Consider a situation: if the temperature decreases by x degrees per day for y days

Temperature decreases by
`x` degrees is denoed by
`-x`.

Therefore,

Total decrease in temperature in
`y` days is denoted by
`-xy`.

So, this situation could be solved using the product of
`xy`, where
`xy` represents a negative value
