True: the equation ax = b has a solution if and only if b is a linear combination of the columns of a. * the equation ax = b is consistent if the augmented matrix [a b] has a pivot position in every row. false: theorem 4 is about a coefficient matrix, not an augmented matrix. if an augmented matrix [a b] has a pivot position in every row, then.

Solutions Midterm Exam 1 Linear Algebra Math 115a Docsity This means w is a linear combination of u and v, which makes u, v, and w linearly dependent. if a is a 2 x 3 matrix and t is a linear transformation defined by t (x) = ax, then the domain of t is r2. false. the domain of t is r3 because x must be a matrix with 3 rows. if one row in an echelon form of an augmented matrix is [0 0 0 5 0], then the. If a linear system has more unknowns than equations, then it must have infinitely many solutions. false. if a and b are 2x2 matrices, then ab=ba. false. the ith row vector of a matrix product ab can be computed by multiplying a by the ith row vector of b. false. tr (ab) = tr (a)tr (b) false. (ab)transpose= (a)trans (b)trans. Of ax = 0, nevermind all their possible linear combinations, which would also be solutions. thus, there are in fact in nitely many vectors sent to the same y value of 0, and this merely by dimension count, because 3 < 5. 5. true or false: the matrix a in problem #1 above is onto. solution: true. first, a can be thought of as a function r4!r2.
