Compute the product using the methods below. If a product is undefined, explain why. a. The definition where Ax is the linear combination of the columns of A using the corresponding entries in x as weights. b. The row-vector rule for computing Ax. 5 -3 a. Set up the linear combination of the columns of A using the corresponding entries in x as weights. Select the correct choice below and, if necessary, fil in any answer boxes to complete your choice. OA. (Type the terms of your expression in the same order as they appear in the original expression.) OB. (Type the terms of your expression in the same order as they appear in the original expression.) OC. The matrix-vector Ax is not defined because the number of columns in matrix A does not match the number of entries in the vector x. O D. The matrix-vector Ax is not defined because the number of rows in matrix A does not match the number of entries in the vector x.
