असमानताओं \(x\geq 0\), \(y\geq 0\), \(x+y\leq 6\), \(x+2y\leq 8\) के हल-क्षेत्र में कितने कोने हैं?
How many corner points are in the solution region of \(x\geq 0\), \(y\geq 0\), \(x+y\leq 6\), and \(x+2y\leq 8\)?
Explanation opens after your attempt
D. (4)
Concept
The corners are ((0,0)), ((6,0)), ((4,2)), and ((0,4)). Hence there are (4) corner points.
Why this answer is correct
The correct answer is D. (4). The corners are ((0,0)), ((6,0)), ((4,2)), and ((0,4)). Hence there are (4) corner points.
Exam Tip
कोने ((0,0)), ((6,0)), ((4,2)), ((0,4)) हैं। इसलिए कुल (4) कोने बनते हैं।
