Express the following linear equations in the form of ax+ by+c=0 and indicate the value of a, b and c in each case. (i) 2x + 3y = 9.3 overline 5 (ii) x - y/5 -10 = 0 (iii) -2x + 3y -6 =0 (iv) x = 3y (v) 2x = -5y (vi) 3x + 2 = 0 (vii) y-2 = 0 (viii) 5 = 2x

Simplify : 3x - [4x - bar(3x -5y) - 3{2x - (3x - bar(2x - 3y))}]

Let bar(a) , bar(b) be non-collinear vectors. If alpha = (x+4y)bar(a)+(2x+y+1)bar(b), beta = (y-2x+2)bar(a)+(2x-3y-1)bar(b) are such that 3alpha = 2beta then find x, y.

If |bar(x)|=7.|bar(y)|=sqrt(2),bar(x)xx bar(y)=(6,2,3) then |bar(x).bar(y)|^(2)= ………. .
