यदि (y=24+6x), तो (x) में कितनी वृद्धि करने पर (y) (42) बढ़ेगा?
If (y=24+6x), by how much must (x) increase for (y) to increase by (42)?
Explanation opens after your attempt
B. (7)
Concept
The total increase is \(6\Delta x\). From \(6\Delta x=42\), \(\Delta x=7\).
Why this answer is correct
The correct answer is B. (7). The total increase is \(6\Delta x\). From \(6\Delta x=42\), \(\Delta x=7\).
Exam Tip
कुल वृद्धि \(6\Delta x\) होगी। \(6\Delta x=42\) से \(\Delta x=7\) मिलता है।
