असमानता \(3x-y\leq 9\) में बिंदु ((0,0)) रखने पर कौन सा परिणाम मिलता है?
What result is obtained by testing ((0,0)) in \(3x-y\leq 9\)?
Explanation opens after your attempt
A. ((0,0)) हल क्षेत्र में है((0,0)) is in the solution region
Concept
Substituting ((0,0)) gives \(0\leq 9\), so the side containing the origin is selected. Use a test point to decide the shading direction in exams.
Why this answer is correct
The correct answer is A. ((0,0)) हल क्षेत्र में है / ((0,0)) is in the solution region. Substituting ((0,0)) gives \(0\leq 9\), so the side containing the origin is selected. Use a test point to decide the shading direction in exams.
Exam Tip
((0,0)) रखने पर \(0\leq 9\) सत्य है, इसलिए मूल बिंदु वाला भाग चुना जाएगा। परीक्षा में परीक्षण बिंदु से छायांकन की दिशा तय करें।
