किस असमानता के लिए सीमा रेखा (3x-y=9) ठोस होगी और ((0,0)) समाधान में नहीं होगा?
For which inequality will the boundary line (3x-y=9) be solid and ((0,0)) not be in the solution?
Explanation opens after your attempt
C. \(3x-y \ge 9\)
Concept
A solid line requires \(\le\) or \(\ge\), and at ((0,0)), \(0 \ge 9\) is false. Hence the origin is not included.
Why this answer is correct
The correct answer is C. \(3x-y \ge 9\). A solid line requires \(\le\) or \(\ge\), and at ((0,0)), \(0 \ge 9\) is false. Hence the origin is not included.
Exam Tip
ठोस रेखा के लिए \(\le\) या \(\ge\) चाहिए और ((0,0)) पर \(0 \ge 9\) असत्य है। इसलिए मूल बिंदु शामिल नहीं होगा।
