Answer:

1:10 P.M.

Step-by-step explanation:

2:05 was the movie duration

2:15 was the soccer duration

5:30 P.M. after soccer

5:30 - 2:15 = 3:15

3:15 - 2:05 = 1:10 (Quick Math)

Since the time did not go below 1 P.M., then it is considered P.M.

3:15 P.M.

There is no solution for the first one

if you eliminate y you get 2 equations
-13x - 13z = -25
-13x - 13x = -15

- there is no solution to theses

a23 means the element in the second row and the 3rd column

so its -5

-2x^2+4x-1 from 6x^2+3x-9

Answer:

$8{x}^{2} - x - 8$

Step-by-step explanation:

We want to subtract

$- 2 {x}^{2} + 4x - 1$

from

$6 {x}^{2} + 3x - 9$

We set up the subtracttion problem to get:

$6 {x}^{2} + 3x - 9 - ( - 2 {x}^{2} + 4x - 1)$

We expand the parenthesis to get:

$6 {x}^{2} + 3x - 9 + 2 {x}^{2} - 4x + 1$

Group similar terms:

$6 {x}^{2} + 2 {x}^{2} + 3x- 4x + 1 - 9$

We simplify to get:

$8{x}^{2} - x - 8$
