क्षेत्र \(x+y\le 7\), \(x-y\le 3\), \(x\ge 0\), \(y\ge 0\) का कौन-सा शीर्ष दोनों तिरछी रेखाओं पर है?
Which vertex of the region \(x+y\le 7\), \(x-y\le 3\), \(x\ge 0\), \(y\ge 0\) lies on both slant lines?
Explanation opens after your attempt
Correct Answer
A. ((5,2))
Concept
Solving (x+y=7) and (x-y=3) gives ((5,2)). A common vertex comes from the intersection of two boundary lines.
Why this answer is correct
The correct answer is A. ((5,2)). Solving (x+y=7) and (x-y=3) gives ((5,2)). A common vertex comes from the intersection of two boundary lines.
Exam Tip
दोनों समीकरणों (x+y=7) और (x-y=3) को हल करने पर ((5,2)) मिलता है। साझा शीर्ष दो सीमा रेखाओं के प्रतिच्छेद से मिलता है।
