System of Equations Using Matrix

Find the values of m and n.

• m = 3, n = -5

• m = 11, n = -5

• m = 3, n = -4

• m = 11, n = -4

Solve for x and y.

• x = 6 and y = 7

• x = 2/3 and y = -5

• x = 1/6 and y = -7

• x = -6 and y = 1/7

Choose the option that would give you the values of k and j.

5k - 6j = 10

-7k + j = 8

Jeffrey wrote a matrix to represent his system of equations. What was his mistake

• The z's are not aligned correctly

• There should be a one in the top row for zero

• There should be a zero in the second column of the third representing the y

• Nothing. This is correct.

Which of the following is the correct representation for the system of equations?

• A

• B

• C

• D

What is the solution to the augmented matrix?

• (3,6,2)

• (3,-5,3)

• (5,5,3)

• ((5/9), (105/9), (-23/9))
