Let T: RR" be a linear transformation with standard matrix A. Which of the following is/are true? (select all that apply) If T is onto, the range of T is Rm. If T is onto, the columns of A are linearly independent. If T is onto, Ax = b has at least one solution for every b in Rm. If T is one-to-one, Ax = 0 has a nontrivial solution. If T is one-to-one, A has a pivot in every row.
