Introduction to Matrices Assignment
Use a piece of paper to create an augmented matrix to represent this linear system.
3x - 4y = 12
2x - 8y = 16
How many rows does your matrix have? - (correct Answer) - 2
How many columns does your matrix have? - (correct Answer) - 3
Given the matrix showing flight times between cities, which of the following statements is true?
The flight time from city 2 to city 4 is 2.1 hours.
The flight time to return from any city is the same as the flight time to fly to that city.
The matrix is square.
Using one or more flights, it is possible to get from any city to any other city. - (correct Answer) - 1,3,4
