रेखा \(y=-\frac{9}{5}x+22\) में (y) को (54) घटाने के लिए (x) कितना बढ़ना चाहिए?
In the line \(y=-\frac{9}{5}x+22\), how much should (x) increase to decrease (y) by (54)?
Explanation opens after your attempt
C. (30)
Concept
The decrease is \(\frac{9}{5}\Delta x\). From \(\frac{9}{5}\Delta x=54\), \(\Delta x=30\).
Why this answer is correct
The correct answer is C. (30). The decrease is \(\frac{9}{5}\Delta x\). From \(\frac{9}{5}\Delta x=54\), \(\Delta x=30\).
Exam Tip
कमी \(\frac{9}{5}\Delta x\) होगी। \(\frac{9}{5}\Delta x=54\) से \(\Delta x=30\) मिलता है।
