WebIn my text there is a T/F statement: If every row of an m × n matrix A contains a pivot position, then the matrix equation A x = b is consistent for every b in R n This is listed as true. I thought about a 2 × 3 matrix... Doesn't this require that since b will be a 2 × 1 matrix, A x = b would be consistent for every b in R m ( R 2 in my example)? Web17 de fev. de 2012 · 1. For each b in R m, the equation A x has a solution 2. Each b in R m is a linear combination of the columns of A. 3. The columns of A span R m 4. A has a pivot position in every row. So when A does not have a pivot in every row, it disproves (1) because each b will not have a solution. How would you disprove (2) with (4)? Answers …
