Let there be two lines 2x+3y+lambda=0 and lambda x-3y-1=0. If the origin lies in the obtuse angle then

If the straight line (2x + 3y +4) +lambda (6x -y + 12) = 0 is parallel to y-axis then lambda=

The pair of lines 6x^(2)+7xy+lambday^(2)=0(lambda ne -6) forms a rightangled triangle with x+3y+4=0 then lambda=

The straight line x+y+1+ lambda (2x-y-1)=0 is bot to 2x+3y-8=0, find the value of lambda .

The value of the lambda if the lines (2x+3y+4)+lambda(6x-y+12)=0 are

If the lines 3x + 4y+ 1 = 0, 5x +lambda y + 3 = 0 and 2x + y-1 = 0 are concurrent, then lambda=

Find the obtuse angle between the lines x-y+2=0 and (2-sqrt(3))x-y+1=0 .

If (lambda^(2),lambda+1) lambda in z belong to the region between the lines x+2y-5 =0 and 3x-y+1=0 which includes the origin then the possible number of such point is

If the equation 3x^2 + 3y^2 + 6lambdax + 2lambda = 0 represents a circle, then the value of lambda . lies in

If origin and (3,2) are contained in the same angle of the lines 2x+y-a=0,x-3y+a=0, then 'a' must lies in the interval -
