Encoding a message starts with assigning each letter of the alphabet with a positive integer using a specific pattern, thus rewriting the original message as a list of numbers instead of words. Decoding a message is the process that "undoes" the encoding process. Assume that the table below was used to encode an important secret message. Z- 26 Blank - 27 U- 21 V- 22 W- 23 X- 24 Y-25 A - 1 F-6 К-11 P- 16 L- 12 М-13 В -2 G-7 Н-8 С -3 D- 4 E-5 N- 14 O- 15 Q-17 R- 18 S- 19 т- 20 1-9 J- 10 You intercepted the following encoded message from Boris and Natasha. 25 19 19 30 41 17 15 26 27 41 15 28 18 41 18 29 41 34 22 19 41 27 15 34 22 You do not know the encoding or decoding function, but you know this message consists of 6 words. Using the encoding system described above, answer the following questions. Analysis 1. From previous work with Boris and Natasha, you know that their encoding and decoding functions are always linear and have 1 as the coefficient of x. Write the general form of the linear function that could be used to decode the message. Inquiry and Evaluation 2. What strategy would you use to decode the message? Write your answer in complete sentences using proper grammar, appropriate capitalization and correct spelling.
