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

all but the second one

step-by-step explanation:

cuz that one goes over 180

answer: i don't understand it

step-by-step explanation: sorry

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
