Answer 3

Class is about to start. I will check later... A few of us discussed it and I am not 100%...

Answer 4

6x4 means 6 equations and 4 variables. The rank of the matrix is at most 4, so if its columns are linearly independent, the number of pivots must be 4

Answer 7

I give you a small matrix to say something about linearly independent
