Unless otherwise specified, assume that all matrices in these exercises are n × n. Determine which of the matrices in Exercises 1–10 are invertible. Use as few calculations as possible. Justify your answers.

MA371: Linear algebra So, you have a matrix… START Is the matrix consistent (1 unique or infinite solution) or inconsistent (no solution) Inconsistent: Consistent: Consistent: the No Solution The solution is only solution is (All Zeros in unique or the zero vector Last column infinite
