=3y=-x" and "6x=-y=-4bar(x)

The angle between the lines 2x = 3y = -z and 6x = -y = -4x is .........

The lines x-y-6=0, 4x-3y-20=0 and 6x+5y+8=0 are:

If |bar(x)|=|bar(y)|=1 and bar(x)_|_bar(y) , then |bar(x)-bar(y)| =……………

Simplify : x - y - {x-y - (x+y)-bar(x-y)}

If |bar(x)|=|bar(y)|=2 and (bar(x)" "^(hat)bar(y))=theta then |bar(x)-bar(y)cos theta| = ………..

Show that x=2,\ \ y=1 and x=4,\ \ y=4 are solutions of the system of equations: 3x-2y=4;\ \ \ 6x-4y=8 .

Solve for x and y : 3x-2y=4 and 6x-4y=8

The equations of sides of a triangle are x+3y=0 , 4x-3y=5 and 3x-y=0. Then the line 6x-7y=0 passes through the __________ of the triangle.

4x-2y=3 6x-3y=5

3x+2y=1, 6x+4y=
