असमानताओं \(x\leq 5\), \(y\leq 3\), \(x+y\geq 4\), \(x\geq 0\), \(y\geq 0\) के हल-क्षेत्र में कितने शीर्ष हैं?
How many vertices are in the solution region of \(x\leq 5\), \(y\leq 3\), \(x+y\geq 4\), \(x\geq 0\), and \(y\geq 0\)?
Explanation opens after your attempt
B. (4)
Concept
Inside the rectangle, the part above (x+y=4) remains. Its vertices are ((1,3)), ((5,3)), ((5,0)), and ((4,0)).
Why this answer is correct
The correct answer is B. (4). Inside the rectangle, the part above (x+y=4) remains. Its vertices are ((1,3)), ((5,3)), ((5,0)), and ((4,0)).
Exam Tip
आयत में रेखा (x+y=4) के ऊपर का भाग बचता है। इसके शीर्ष ((1,3)), ((5,3)), ((5,0)), ((4,0)) हैं।
