$Suppose A is a 5\times 7 matrix. How many pivot columns must A …$

WebSolution: A set of three vectors can not span R4. To see this, let A be the 4 3 matrix whose columns are the three vectors. This matrix has at most three pivot columns. This means that the last row of the echelon form U of Acontains only zeros. Like in the previous problem, that implies that the columns of A can not span R4. WebThe third column does not contain a pivot, so x 3 is an independent variable. Therefore, there are infinitely many solutions for x 1 and x 2, and x 3 can be chosen freely. x 1 = 2 - 3 x 3 x 2 = 4 - 2 x 3. For example, if x 3 = 1, then x 1 = - 1 and x 2 = 2.
