Math Problem Statement
Consider a system A x = b Ax=b of 4 4 linear equations in 5 5 variables. Which of the following statements is true? The system A x = b Ax=b is consistent if and only if b b is a linear combination of the 5 5 columns of A A. The system A x = b Ax=b is consistent if and only if A A is a linear combination of the column of b b. The system A x = b Ax=b is consistent if and only if A A is a linear combination of the 5 5 columns of b b. The system A x = b Ax=b is consistent if and only if b b is a linear combination of the 4 4 columns of A A.
