(1) Encode a message! (a) Come up with a three to five word phrase. Be sure and write it down and then convert your message to uncoded row matrices. (b) Choose any size invertible matrix to use for creating your encoded row matrices. Be sure to verify your matrho is inveritble (e) Encode your meesage using the invertible matris you chose in part (b), Display your answersa yptogra not in matrix notation. (2) Decode the the cryptogram 32 -14 9 -25 14 11 86 17 -48 72 -12 -45 49 -2 -35 55 -8 -33 -5 5 0 -1 1 0 using the inverse of the matrix A =-0 i I· [Hint: You will need to find A-㪠Section 3.4 (1) Use Cramer's Rule to Solve the systems below, if possible. If you cannot use Cramer's rule, explain why and solve the system using another method. (b) 2z +2y + 3 10
