Identify a redundant constraint
Problem
In \(x\le~10\), \(x\le~15\), \(x\ge~0\), identify the redundant constraint and its stronger companion.
Big Picture
What this problem is really about
A redundant constraint is one that adds no restriction beyond what another condition already guarantees. We’ll compare the two upper bounds to find the tighter one, test which implication works, and then imagine removing the looser bound. If the feasible interval stays unchanged, that looser statement is redundant while the tighter bound is its stronger companion.
