Find the determinant of the following matrix as a formula in terms of a and y. 1 0 1 0 -1 2 x 1 Ay det (A)

Compute the determinant of the matrix A, below, by using row operations to transform A to an upper-triangular matrix B. Then express the determinant of A as a multiple k of the determinant of B, and use this to compute the determinant of A. A = 2 -3 -7 -5 -6 13 30 15 0 -2 6 0 4 -2 0 0 000 B=000 000
