alleryIf y is inversely proportional to x, which quantity stays constant?
Ax + y
Bx - y
Cx / y
Dx times y
Answer & Solution
Correct answer: D. x times y
1. Inverse proportion means y = k/x.
2. Multiplying both sides by x gives xy = k.
3. So the product of x and y stays constant, not their sum or quotient.
