Three lines `3x+4y+6=0, sqrt(2) x + sqrt(3) y + 2sqrt(2)=0 and 4x+7y+8=0` are (A) sides of triangle (B) concurrent (C) parallel (D) none of these

Statement 1: Lines 3x+4y+6=0,sqrt(2)x+sqrt(3)y+2sqrt(2)=0 and 4x+7y+8=0 are concurrent. Statement 2 : If three lines are concurrent then determinant of coefficients should be non-zero.

{:(sqrt(5)x - sqrt(7)y = 0),(sqrt(7)x - sqrt(3)y = 0):}

(v) Solve for x and y if (sqrt2 x+sqrt 3 y)=0 and (sqrt3 x- sqrt8 y)=0

The lines represented by the equation x^2 + 2sqrt(3)xy + 3y^(2) -3x -3sqrt(3)y -4=0 , are

The lines x+y-1=0,(m-1)x+(m^2-7)y-5=0, and (m-2)x+(2m-5)y=0 are a) concurrent for three values of m b) concurrent for one value of m c) concurrent for no value of m d) parallel for m=3.

If the quadrilateral formed by the lines ax+by+c=0, 6sqrt(3)x+8sqrt(3)y+k=0 , ax+by+k=0 and 6sqrt(3)x + 8sqrt(3)y+c=0 has diagonals at right angles, then the value of a^2 +b^2 = …

Prove that the lines sqrt(3)x+y=0,\ sqrt(3)y+x=0,\ sqrt(3)x+y=1\ a n d\ sqrt(3)y+x=1 form a rhombus.

Show that the lines 2x + 3y - 8 = 0 , x - 5y + 9 = 0 and 3x + 4y - 11 = 0 are concurrent.

Given three straight lines 2x+11 y-5=0,24 x+7y-20=0, and 4x-3y-2=0 . Then, a)they form a triangle b)one line bisects the angle between the other two c) two of them are parallel

The equations of the lines which pass through the point (3,-2) and are inclined at 60^(@) to the line sqrt(3)x+y=1 are (i) y+2=0,sqrt(3)x-y-2-3sqrt(3)=0 (ii) x-2=0,sqrt(3)x-y+2+3sqrt(3)=0 (iii) x-3=0,sqrt(3)x-y-2-3sqrt(3)=0 (iv) none of these
