Perform the indicated matrix operations. If an expression is undefined, explain why. Let C= 12 -31 Find 4C-2E -5 [+] 4 and E= OA. 4C-2E= (Click on the answer box and then select the matrix icon below) B. The expression 4C-2E is undefined because 4C and 2E have different dimensions. OC. The expression 4C-2E is undefined because the number of rows in C is not equal to the number of columns in E. O D. The expression 4C-2E is undefined because E is not a square matrix.
Determine whether the statement below is true or false. Justify the answer. The equation Ax=b is consistent if the augmented matrix [a b] has a pivot position in every row. Choose the correct answer below. C A. This statement is false. The augmented matrix A b than rows. OB. This statement is true. The pivot positions in the augmented matrix [ A b] always occur in the columns that represent A. OC. This statement is true. If the augmented matrix [ A b] has a pivot position in every row, then the equation Ax=b has a solution for each b in R™. cannot have a pivot position in every row because it has more columns D. This statement is false. If the augmented matrix [ A b] has a pivot position in every row, the equation Ax = b may or may not be consistent. One pivot position may be in the column representing b.
