If x ∝ 1/y and y ∝ 1/z, then _____?
- x ∝ z
- y ∝ z
- xy ∝ z
- None of these
Explanation
Given:
x ∝ 1/y
y ∝ 1/z
We can rewrite these proportions as:
x = k₁/y (where k₁ is a constant)
y = k₂/z (where k₂ is a constant)
Substitute the expression for y into the first equation:
x = k₁/(k₂/z)
Simplify:
x = k₁z/k₂
x ∝ z
