Suppose a 4x7 coeficient matrix for a system has four pivot columns. Is the system consistent? Why or why not? Choose the corect answer below. OA. There is a pivot position in each raw of the coefficient matrix. The auugmented matrix will have five columns and will not have a row of the form so the system is consistent. n o o 0 1 O B. There is a pivot position in each row of the coefficient matrix. The augmented...

4) a) For the system of equations given, partially row reduce the coefficient matrix in the following careful way: *1 + 2y, - 2 = 5 4x1 +9y1 - 32 = 8 (5x + 12y - 321 = 1 Stage 1: just reduce the matrix first to an upper triangular form U and leave pivot entries as they are (don't multiple to change them to 1's). Reduce from left to right through the columns and from the pivot entry down...
