14. If you were to use Gauss-Jordan elimination on the following linear system, what would the augmented matrix be? 3w - x = 2y + 2 - 4
9x - y + z = 10
4w + 3y - 2 = 7
12x + 17 = 2y - Z + 6
3 -1 7
13 -1 -2 -1
-1 0 1
A.
0 3 - 1
12 -2 10
13-1 2 1-4
09-1 110
B.
o 12 2 -1 6
13 -1 -2 -1 -4
To 9-1 1 10
c.
0 3 -1
O 12 2 1
3 -1 -2 -1
-1 1
D.
o 3 -1
LO 12-2 1 -11

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

the answer is c.

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
