असमता (-2(4x-3)\geq 10) का हल कौन सा है?
What is the solution of (-2(4x-3)\geq 10)?
Explanation opens after your attempt
Correct Answer
A. \(x\leq -\frac{1}{2}\)
Concept
Simplifying gives \(-8x+6\geq 10\), then \(-8x\geq 4\), so \(x\leq -\frac{1}{2}\). Reverse the sign when dividing by a negative coefficient.
Why this answer is correct
The correct answer is A. \(x\leq -\frac{1}{2}\). Simplifying gives \(-8x+6\geq 10\), then \(-8x\geq 4\), so \(x\leq -\frac{1}{2}\). Reverse the sign when dividing by a negative coefficient.
Exam Tip
सरलीकरण से \(-8x+6\geq 10\), फिर \(-8x\geq 4\) और \(x\leq -\frac{1}{2}\) मिलता है। ऋणात्मक गुणांक से भाग देते समय चिन्ह पलटें।
