Use a graphing utility to find the inverse, if it exists, of the given matrix. Select the correct choice below and, if necessary, fill in the answer box within your choice. OA. The inverse of the matrix 25 57 - 17 21-2 8 is -9 40 27 (Type an integer or decimal for each matrix element. Round to two decimal places as needed.) O B. The matrix has no inverse. 25 57 - 17 21 - 2 8 -9 40 27 ४ Use the given inverse of the coefficient matrix to solve the following system of equations. -0.06 -0.02 0.56 25x + 62y - 12z = 10 0.10 0.07 -0.75 18x12y + 7z= -9 0.32 0.31 -2.72 5x + 6y- z = 13 The solution is x = y = and z= (Round to two decimal places as needed.)
