3x÷2-5y÷2=0
2x-3y+10=0
Solve the following system of linear equations graphically and shade the region between the two lines and x-axis;
(i) 2x + 3y = 12,
x - y = 1
(ii) 3x + 2y - 4 = 0,
2x - 3y - 7 = 0
(iii) 3x + 2y - 11 = 0
2x - 3y + 10 = 0
In the following exericise determine whether the given planes are parallel or perpendicular and in case they are neither, find the angle between them.
7x +5y +6z+ 30 =0 and 3x -y- 10z+ 4=0
2x+y+3z-2=0 and x-2y+5=0
2x- 2y+ 4z+ 5= 0 and 3x- 3y+ 6z- 1= 0
2x-y+3z-1=0 and 2x-y+3z+3=0
4x+8y+z-8=0 and y+z-4=0
