    Showing that a basis for the ker(A) is in the kernel

    yeah, if i take my basis for the ker(A) and plug the vaules back into the original system i get all of the equations to equal zero. is that right then? thanks for the help by the way :)

    Showing that a basis for the ker(A) is in the kernel

    I'm not sure what " maps to the zero vector" means, this is my first course in Linear Algerbra ( two class periods so far ) and we don't have a book to work from. After I reduce the matrix A|B I get 1 0 0 -1 | 0 0 1 0 1 | 2 0 0 1 0 | 1 which gives x -w...

    Showing that a basis for the ker(A) is in the kernel

    Homework Statement I'm new to this and I was wondering if anyone could help me out given: x+z-w=1 y-z+w=1 x+y+z=3 find the coefficient matrix A, the vector of constants B, use Gauss-jordan elimination to solve the system. Find the Rank(A), the Null(A) and a basis for the im(A) and a...
