Translate the problem situation to a system of equations. Do not solve.The Cudly College football team scored 101 times last season, some seven-point touchdowns and some three-point field goals. Altogether the 101 scores accounted for 503 points. How many of each type of score was accomplished?
A. x + y = 101; 7x + 3y = 503 B. x - y = 101; 7x - 3y = 503 C. x + y = 503; 7x + 3y = 101 D. x + 3y = 101; 7x + y = 503
Secret messages can be encoded by using a code and an encoding matrix. If we have the code:
and an encoding matrix E, we can encode a message by taking every two letters of the message, converting them to their corresponding numbers, creating a 2 × 1 matrix, and then multiplying each two numbers by E. The message may be unscrambled with a decoding matrix which is the inverse of the coding matrix, E-1. Determine if the given pair of encoding matrices are inverses of each
other.
