Calvin 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, he multiplied the clear text code for each letter by the matrix cap c is equal to the 2 by 2 matrix, row 1, column 1, 3 column 2, negative 2 row 2, column 1, 4 column 2, negative 3 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, 24 column 2, 6 column 3, negative 23 column 4, 5 column 5, 21 column 6, negative 6 column 7, 35 row 2, column 1, 26 column 2, 5 column 3, negative 37 column 4, 6 column 5, 24 column 6, negative 15 column 7, 45 What is the secret phrase? Determine the location of spaces after you decode the text.
