प्रथम चतुर्थांश में \(x\ge 2\), \(y\ge 1\), \(x+y\le 8\) से बने क्षेत्र का एक शीर्ष कौन-सा है?
In the first quadrant, which is a vertex of the region \(x\ge 2\), \(y\ge 1\), \(x+y\le 8\)?
Explanation opens after your attempt
Correct Answer
A. ((2,1))
Concept
The lines (x=2) and (y=1) meet at ((2,1)), and it also satisfies \(x+y\le 8\). Check every vertex in all inequalities.
Why this answer is correct
The correct answer is A. ((2,1)). The lines (x=2) and (y=1) meet at ((2,1)), and it also satisfies \(x+y\le 8\). Check every vertex in all inequalities.
Exam Tip
रेखाएं (x=2) और (y=1) मिलकर ((2,1)) देती हैं और यह \(x+y\le 8\) को भी संतुष्ट करता है। हर शीर्ष को सभी असमानताओं में जांचें।
