Linear Algebra

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...

Null Space Solution Space of a homogenous system Nullity Dimension of the Null space Dimension Number of vectors that form a basis. (non zero rows in a rref matrix Linearly dependent When the sum of subspace multiplied by a non-zero constant equals the zero vector Gram Schmidt Consistent has a solution

If the row reduced echelon form of A involves free variables, then the system Ax = b will have infinitely many solutions correct answers FALSE if the system is consistent, and has free variables, it has infinitely many solutions if the system is inconsistent, and has free variables, its does not have infinitely many solutions Every homogeneous linear system is consistent correct answers TRUE every homogenous linear system has zero vectors as the solution An nxn matrix A is nonsign...
