Medium Mathematics Introduction to Polynomials Class 9 Level 37

किस नियम में आरंभिक मान (210) और प्रति चरण (14) की कमी है?

Which rule has initial value (210) and decrease of (14) per step?

Explanation opens after your attempt
Correct Answer

D. (y=210-14x)

Step 1

Concept

For decrease, the coefficient of (x) must be negative. So (y=210-14x) is the correct model.

Step 2

Why this answer is correct

The correct answer is D. (y=210-14x). For decrease, the coefficient of (x) must be negative. So (y=210-14x) is the correct model.

Step 3

Exam Tip

कमी के लिए (x) का गुणांक ऋणात्मक होगा। इसलिए (y=210-14x) सही मॉडल है।
