Linear Algebra Exam Questions with Answers 1.1 10. d. Is the statement "Two fundamental questions about a linear system involve existence and uniqueness" true or false? Explain. - Answer-True, because two fundamental questions address whether the solution exists and whether there is only one solution. 1.1 11. a. Is the statement "Two matrices are row equivalent if they have the same number of rows" true or false? Explain. - Answer-False, because if two matrices are row equiv...

Matrix inverses are analogous to the multiplicative inverse (or reciprocal) in the number system. In the number system, the multiplicative inverse, if it exists, is unique. Indeed, the matrix inverse, if it exists, is also unique similarly, as shown in the following proposition. is invertible and its inverse is since (it implies that the matrix product in another order is also by the invertible matrix theorem) ...

Is the statement "Two matrices are row equivalent if they have the same number of rows" true or false? Explain. - False, because if two matrices are row equivalent it means that there exists a sequence of row operations that transforms one matrix to the other Is the statement "Elementary row operations on an augmented matrix never change the solution set of the associated linear system" true or false? Explain. - True, because the elementary row operations replace a system with an eq...

Is the statement "Two matrices are row equivalent if they have the same number of rows" true or false? Explain.False, because if two matrices are row equivalent it means that there exists a sequence of row operations that transforms one matrix to the other Is the statement "Elementary row operations on an augmented matrix never change the solution set of the associated linear system" true or false? Explain.True, because the elementary row operations replace a system with an equivale...

Augmented Matrix correct answers a coefficient matrix with an extra column containing the constant terms Consistent system correct answers a system of equations or inequalities that has at least one solution Is the statement "Every elementary row operation is reversible" true or false? correct answers True, because replacement, interchanging, and scaling are all reversible. Is the statement "A 5×6 matrix has six rows" true or false? correct answers False, because a 5×6 matri...

Linear combination Correct Answer The addition of two or more vectors, each of which can have any weight (scalar). C1v1 + c2v2 + c3v3 Weight Correct Answer The scalar for one of the vectors in a linear combination. Span{v} Correct Answer The set of all vectors of the form cv. Span{v1, v2, v3, ..., vn} Correct Answer The set of all linear combinations of True or false: A linear system has only one unique solution, no solution at all, or infinitely many solutions. Correct Answer True ...

Example 1.10. There are six different 3 × 3 permutation matrices, namely ⎛ ⎝ 1 0 0 0 1 0 0 0 1 ⎞ ⎠, ⎛ ⎝ 0 1 0 0 0 1 1 0 0 ⎞ ⎠, ⎛ ⎝ 0 0 1 1 0 0 0 1 0 ⎞ ⎠, ⎛ ⎝ 0 1 0 1 0 0 0 0 1 ⎞ ⎠, ⎛ ⎝ 0 0 1 0 1 0 1 0 0 ⎞ ⎠, ⎛ ⎝ 1 0 0 0 0 1 0 1 0 ⎞ ⎠. (1.30) These have the following effects: if A is a matrix with row vectors r 1, r 2, r 3, then multiplication on the left by each of the six permutation matrices produc...
