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

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

Step-by-step explanation:

A rational number is a number of the form 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 degrees is denoed by .

Therefore,

Total decrease in temperature in days is denoted by .

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

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
