Question

Which statements are true about the ordered pair (−4, 0) and the system of equations?
{2x+y=−8
x−y=−4
Select each correct answer.
The ordered pair (−4, 0) is a solution to the first equation because it makes the first equation true.
The ordered pair (−4, 0) is a solution to the second equation because it makes the second equation true.
The ordered pair (−4, 0) is not a solution to the system because it makes at least one of the equations false.
The ordered pair (−4, 0) is a solution to the system because it makes both equations true.

Answer 1

Answer:

first, second, and fourth are correct

Step-by-step explanation:

2(-4) + 0 = -8; this is correct because -8 + 0 = -8

(-4) - 0 = -4; this is correct because -4 - 0 = -4

We know that they are both true, so the fourth choice is true as well.
