The solution set of the matrix equation ax-b is explored in the video.
If b is a linear combination of the columns of A, it has a solution.If A does not have a pivot in every row, that doesn't mean that there is no solution for it.It does not mean that there is a solution.
There is a question about what is in Ax B.A definition.If A is an m n matrix, with columns a1,a2,an, and x in Rn, then the linear combination of the columns of A using the corresponding is what the product is.The weights are entries in x.
A linear combination of the columns of a matrix A if and only if the equation has at least one solution is called a vector b.Is it T/F?It's true.The equation is the same as the equation x(1) a(1)
There is no solution to the equation.There are no requirements for the entries of b to satisfy if the matrix R + I F has no rows of zeros.The equation is easy to solve for every b.
