Question

If x and y are two quantities and xy = const constant then x and y are proportional to each other​

Answer 1

Answer:

• If two quantities x and y vary (change) together in such a manner that the ratio of their corresponding values remains constant, then x and y are said to be in direct proportion.

• if two quantities x and y vary (change) in such a manner that an increase in x causes a proportional decrease in y (and vice versa), then x and y are said to be inverse proportion.

• If x and y are in a direct proportion, then

• If x and y are in an inverse variation, then xy = constant.
