1. Write a matrix for the system of equations. A. B. C. D. Hint 2. Write the matrix equation as a system of linear equations. A. -2s = 75t = 12 B. -2s + t = 125s + 8t = 7 C. -2s + 5t = 7s + 8t = 12 D. -2s + t = 75s + 8t = 12 Hint 3. What is the first step in solving the matrix equation A. Find the inverse of B. Multiply each side of the matrix equation by the identity matrix. C. Multiply each side of the matrix equation by D. Divide each side of the matrix equation by Hint 4. In a sport similar to football, there are two ways to score: by the run or by the pass. Team A scored 244 points, while Team B scored 273 points. Team A scored by the pass 21 times, and by the run 11 times. Team B scored by the pass 27 times, and by the run 6 times. How many points is each score worth? A. pass = 5 pointsrun = 23 points B. pass = 5 pointsrun = 9 points C. pass = 7 pointsrun = 14 points D. pass = 9 pointsrun = 5 points Hint 5. Solve the system of equations 7x – 14y =4, 3x – 6y =17.
