2x+y>=8,x+2y>=10

Solve the following simultaneous linear equations in two variables by the method of comparison : 4/x-y/2=-1 8/x+2y=10

2x + y ge 8, x + 2y ge 10

2x + y ge 8, x + 2y ge 10

Maximize z = 5x + 7y such that 2x + y ge 8, x + 2y ge 10 x, y ge 0 .

The point at which the minimum value of z = 8x + 12y subject to the constraints 2x +y ge 8, x + 2y ge 10 x ge 0, y ge 0 is obtained is

The transformed equation of x^(2)+6 x y+8 y^(2)=10 when the axes are rotated through an angle (pi)/(4) is

The lines x+2y+3=0,x+2y-7=0, and 2x-y-4=0=0 are the sides of a square.The equation of the remaining side of the square can be (a) 2x-y+6=0 (b) 2x-y+8=0 (c) 2x-y-10=0 (d) 2x-y-14=0

The lines x+2y+3=0,x+2y-7=0,a n d2x-y-4=0 are the sides of a square. The equation of the remaining side of the square can be (a) 2x-y+6=0 (b) 2x-y+8=0 (c) 2x-y-10=0 (d) 2x-y-14=0
