Solve : 3( 2u +v) = 7uv 3(u + 3v) = 11 uv

The component forms of vectors u and v are given by u = u = (:5,3:) and v = (:2,-7:) . Given that 2u + (-3v) + w = 0 , what is the component form of w?

Find the value of (-8u^(2)v^(6)) xx(-20uv) for u = 2.5 and v = 1.

What is the value of u in the system of equations 3 (2u + v) = 7uv, 3 (u + 3v) = 11uv ?

If (u^2+v^2) prop (x^2 +y^2 ) and uv prop xy then show that (u+v) prop (x+y) when u/v+v/u=x/y +y/x .
