QUESTION 1 A series of 4 elementary matrices true: are left-multiplied by Matrix with size nxn, resulting in the Identity matrix: - rrrr represent the row operations needed for Gaussian elimination to convert A into reduced-row echelon form (RREF) It is not known whether of linear equations Ax = b will have unique solutions or not. O can be written as a product of elementary matricies. EEEE=A-1 2 1 4321 .. Choose the following statements that are QUESTION 2 Select the following true statements about matrix inverses As it relates to the existence of solutions in any system of linear equations Ax=b it doesn't matter what the value of A is. It just matters if it is zero or not. The determinant of a 3x3 matrix A is 1. The determinant of 2A is 2. To calculate the matrix determinant, the matrix must be square. If the determinant of a matrix A is zero, it will have infinite solutions in any system of linear equations Ax=b The determinant of a matrix is zero. This means the inverse of the matrix is the zero matrix.
