असमानता (y< -x+7) और \(y\ge x-1\) के संयुक्त हल के लिए कौन सा (x) मान संभव है?
For the common solution of (y< -x+7) and \(y\ge x-1\), which value of (x) is possible?
Explanation opens after your attempt
A. (x<4)
Concept
We need (x-1< -x+7), so (2x<8) and (x<4). For a region between two lines, compare the upper and lower bounds.
Why this answer is correct
The correct answer is A. (x<4). We need (x-1< -x+7), so (2x<8) and (x<4). For a region between two lines, compare the upper and lower bounds.
Exam Tip
हमें (x-1< -x+7) चाहिए, इसलिए (2x<8) और (x<4) मिलता है। दो रेखाओं के बीच क्षेत्र में ऊपरी और निचली सीमा की तुलना करें।
