यदि (y=330-22x), तो (y) में (154) की कमी के लिए (x) कितना बढ़ना चाहिए?
If (y=330-22x), by how much should (x) increase for (y) to decrease by (154)?
Explanation opens after your attempt
C. (7)
Concept
The total decrease is \(22\Delta x\). From \(22\Delta x=154\), \(\Delta x=7\).
Why this answer is correct
The correct answer is C. (7). The total decrease is \(22\Delta x\). From \(22\Delta x=154\), \(\Delta x=7\).
Exam Tip
कुल कमी \(22\Delta x\) होगी। \(22\Delta x=154\) से \(\Delta x=7\) मिलता है।
