यदि (p(x)=mx+n), (p(0)=-8) और (p(5)=27), तो (m+n) क्या है?
If (p(x)=mx+n), (p(0)=-8) and (p(5)=27), what is (m+n)?
Explanation opens after your attempt
A. (-1)
Concept
(p(0)=n=-8) and (5m-8=27) gives (m=7). Therefore (m+n=-1).
Why this answer is correct
The correct answer is A. (-1). (p(0)=n=-8) and (5m-8=27) gives (m=7). Therefore (m+n=-1).
Exam Tip
(p(0)=n=-8) और (5m-8=27) से (m=7) मिलता है। इसलिए (m+n=-1) है।
