असमानताओं \(x\geq 0\), \(y\geq 0\), \(2x+y\geq 8\), \(x+3y\geq 9\) के हल-क्षेत्र में कौन सा बिंदु शामिल है?
Which point is included in the solution region of \(x\geq 0\), \(y\geq 0\), \(2x+y\geq 8\), and \(x+3y\geq 9\)?
Explanation opens after your attempt
D. ((4,2))
Concept
At ((4,2)), (2x+y=10) and (x+3y=10). Choose the final option only after substituting the point in all inequalities.
Why this answer is correct
The correct answer is D. ((4,2)). At ((4,2)), (2x+y=10) and (x+3y=10). Choose the final option only after substituting the point in all inequalities.
Exam Tip
((4,2)) पर (2x+y=10) और (x+3y=10) मिलता है। सभी असमानताओं में बिंदु रखकर ही अंतिम विकल्प चुनें।
