असमानता \(5-2x\leq x+11\) का हल अंतराल कौन सा है?
Which interval is the solution of \(5-2x\leq x+11\)?
Explanation opens after your attempt
A. \( [-2,\infty\) )
Concept
\(5-2x\leq x+11\) gives \(-3x\leq 6\), so \(x\geq -2\). Division by a negative coefficient reverses the sign.
Why this answer is correct
The correct answer is A. \( [-2,\infty\) ). \(5-2x\leq x+11\) gives \(-3x\leq 6\), so \(x\geq -2\). Division by a negative coefficient reverses the sign.
