1. The columns of a 7⇥5 matrix are linearly independent. How many pivot columns does it have? 2. List all possible echelon forms of the matrix in each case (indicate non zero elements with ⇤ and pivots with a square). (a) A is a 2⇥2 matrix with linearly dependent columns (b) A is a 4⇥2 matrix [~v 1 ~v 2], and~ v 2 is not a multiple of~ v 1.

How many pivot columns must a 5×7 matrix have if its columns span R5? Since there must be a pivot in each row, there would have to be 5 pivot columns so that the equation Ax = 0 will have at least one solution. Construct 3×2 matrices A and B such that Ax = 0 has only the trivial solution and Bx = 0 has a nontrivial solution.

Instant Answer EXPERT VERIFIED Step 1/6 1. A 7 × 5 7 × 5 matrix has 7 rows and 5 columns. Step 2/6 2. If the columns are linearly independent, that means no column can be written as a linear combination of the other columns. Step 3/6 3. In order for the columns to be linearly independent, there must be a pivot (leading 1) in each column. Step 4/6
