Yvette encoded a secret phrase using matrix multiplication. Using cap A is equal to 1 , cap b is equal to 2 , cap c is equal to 3 , and so on, she multiplied the clear text code for each letter by the matrix cap c is equal to the 2 by 2 matrix row 1, 5 2 row 2, 2 1 to get a matrix that represents the encoded text. The matrix representing the encoded text is the 2 by 7 matrix, row 1, column 1, 48 column 2, 73 column 3, 114 column 4, 30 column 5, 136 column 6, 78 column 7, 35 row 2, column 1, 21 column 2, 32 column 3, 50 column 4, 13 column 5, 58 column 6, 35 column 7, 15 What is the secret phrase?
