The line x - 2y + 3 = 0 , 3x - y = 1 and kx - y + 1 = 0 are concurrent . Find k .

The equation of the line which intersect each of the two lines 2x+y-1 =0 =x-2y+3z and 3x -y+z+2 = 0 = 4x + 5y - 2z-3 = 0 and is parallel to (x)/(1)=(y)/(2)=(z)/(3) is

Solve for x and y: 2x + 3y + 1 = 0, 3x + 2y - 11 = 0

(2x -2y+3) dx -(x-y+1) dy=0 , " when" x=0, y=1

Let Y = y(x) be the solution of the differential equation ( dy ) /( dx) + 2y = f(x) , where f(x) = { {:(1, x in [0,1]),( 0, " Otherwise "):} IF y(0) =0 then y ((3)/(2)) is :

Find the point of intersection of the straight lines : (i) 2x+3y-6=0 , 3x-2y-6=0 (ii) x=0 , 2x-y+3=0 (iii) (x)/(3)-(y)/(4)=0 , (x)/(2)+(y)/(3)=1

(3) / (x) - (1) / (y) + 9 = 0 (2) / (x) + (3) / (y) = 5, (! = 0, y! = 0)

If (2, -2),(-1,2), (3,5) are the vertices of a triangle then the equation of the side not passing through (2,-2) is (A) x + 2y +1 = 0 (B) 2x - y- 4= 0 (C) X-3y -3= 0 (D) 3x – 4y + 11 = 0

The equation of the line joining through the points of intersection of lines 2x - y + 3 = 0 and 3x + y + 7 = 0 and perpendicular to 2x - 3y + 4 = 0 , is "________" . (a) 3x + 2y - 7 0 " " (b) 3x + 2y + 8 = 0 " " (c) 3x + 2y - 8 = 0 " " (d) 3x - 2y + 1 = 0
