WebIn such a case, the pair of linear equations is said to be dependent and consistent. As represented in the graph below, the pair of lines coincide and, therefore, dependent and …

Webfor any m n matrix A: (a) For every b, the equation Ax = b has a solution. (b) Every column vector b (with m entries) is a linear combination of the columns of A. (c) The columns of A span Rm (this is just a restatement of (b), once you know what the word \span" means). (d) A has a pivot in every row. WebSep 17, 2024 · If the matrix vector equation A x → = b → is consistent, then the steps involved in putting [ A b →] into reduced row echelon form depend only on A; it does not matter what b → is.
