Engineering Math Exam Questions

1. The document discusses a system of linear equations and properties of matrices. 2. It states that if a matrix A is invertible, then the system of equations Ax = b has a unique solution for any vector b. 3. It also notes that the rank of a matrix is always less than or equal to its smallest dimension, and that a system of m equations in n unknowns has a unique solution if the matrix has full rank, which is min(m,n).
