कौन सा बिंदु \(2x+y\geq 7\), \(x+2y\leq 12\), \(x\geq 0\), \(y\geq 0\) का हल है?
Which point is a solution of \(2x+y\geq 7\), \(x+2y\leq 12\), \(x\geq 0\), and \(y\geq 0\)?
Explanation opens after your attempt
B. ((3,3))
Concept
Substituting ((3,3)) gives (2x+y=9) and (x+2y=9). In point testing, check every inequality separately.
Why this answer is correct
The correct answer is B. ((3,3)). Substituting ((3,3)) gives (2x+y=9) and (x+2y=9). In point testing, check every inequality separately.
Exam Tip
((3,3)) रखने पर (2x+y=9) और (x+2y=9) मिलता है। बिंदु जांच में सभी असमानताओं को अलग-अलग जांचें।
