Unless otherwise specified, assume that all matrices in these exercises are $n \times n .$ Determine which of the matrices in Exercises $1-10$ are invertible. Use as few calculations as possible. Justify your answers. $$ \left[\begin{array}{rrr}{5} & {0} & {0} \\ {-3} & {-7} & {0} \\ {8} & {5} & {-1}\end{array}\right] $$
