Notation: For a 3x3 matrix: • We will denote by m², the minor of order 2 obtained by deleting row i and column j. • We will denote by m; the minor of order 1 obtained by deleting every row but i and every column but j. • We will denote by pm? = m²; the principal minor of order 2 obtained by deleting row i and column i. • We will denote by pm = m; the principal minor of order 1 obtained by deleting every row by i and every column but i. • We will denote by 1pm the leading principal minor of order k. Calculate the following minors of A = -4 2 -5 -5 -5 1 5 -1 -2 (a) The minor of order 3 (b) The minor m3,2 of order 2 (c) The minor m of order 1 (d) The principal minor pm² of order 2 (e) The leading principal minor 1pm2 of order 2

(Only use elementary row operations and correct row operation notation.)

The figure to the right shows the letter L in a rectangular coordinate system. The figure can be represented by the matrix B, shown to the right. Each column in the matrix describes a point on the letter. The order of the columns shows the direction in which a pencil must move to draw the letter. The Lis completed by connecting the last point in the matrix, (0,5), to the starting point, (0,0). Use matrix operations to move the L 5 units to the right and 4 units up. Then graph the L and its transformation in a rectangular coordinate system. ... B= C 033110 0 0 1 1 5 5 N Determine the matrix operation that will move the L 5 units to the right and 4 units up and perform the operation. What is the result?
