How many pairs of (x,y) satisfy the equations 3x+6y=21 and 4x+8y=16

4 years ago

Share

Answers : (4)

										

as 3/4=6/8  so these lines are parallel, i.e. have no common point, so 0 pairs of (x,y) will satisfy this

3x + 6y = 21


or, x+2y=7


 


4x+8y=16


x+2y=4


 


Inconsistent equations. No solution.

dear suresh,


these two equations reaemble two parallel lines as a1/a2=b1/b2not equal to c1/c2.


so these two lines never intersect and thus have no solution

3 years ago
										

no solution since they are parallel lines
please post some tough questions next time

if a,b,c are positive real numbers such that loga/(b-c) = logb/(c-a) = logc/(a-b) then proove that a (b+c) + b ( c+a) + c (a+b) >= 3 a (a) + b (b ) + c (c) >= 3

loga/(b-c) = logb/(c-a) = logc/(a-b) = k (let)(b-c)(loga)/(b-c)^2 = ka^(b-c) = e^(k(b-c)^2)......................(1)Similarly,c^(a-b) = e^(k(a-b)^2)....................(2)b^(c-a) =...
