Questions
detailed solution
Correct option is A
The equation of the plane through the line of intersection of the planes 4x + 7y + 4z + 81 = 0 and 5x + 3y + 10z = 25 is (4x+7y+4z+81)+λ(5x+3y+10z−25)=0or (4+5λ)x+(7+3λ)y+(4+10λ)z+81−25λ=0-----i which is perpendicular to 4x+7y+4z+81=0⇒4(4+5λ)+7(7+3λ)+4(4+10λ)=0or 81λ+81=0or λ=−1 Hence, the plane is x−4y+6z=106Talk to our academic expert!
