C{NEGATIVE1,2}
D{2,2}
It is a trivial matter to put in each of the answers to see if the equation balances, much faster than posting on our forum.
this does my brain a hurt
1. C
2. A
3. A
4. C
@You're welcome. is correct i got all of the answers correct and also people answer the questions yourself then come on here to check
Thanks. @You're Welcome. 3/4
To determine which ordered pair is a solution to the given system of linear equations, you can substitute the values of the given coordinates into each equation and check if the equation holds true.
Let's test each option one by one:
Option A: (-6, 0)
Substituting these values into the equations, we get:
2(-6) - 5(0) = -12
-12 + 0 = -12, which is true for the first equation.
And,
-(-6) + 4(0) = 9
6 + 0 = 9, which is not true for the second equation.
Option B: (3, 3)
Substituting these values into the equations, we get:
2(3) - 5(3) = -12
6 - 15 = -12, which is not true for the first equation.
And,
-(3) + 4(3) = 9
-3 + 12 = 9, which is true for the second equation.
Option C: (-1, 2)
Substituting these values into the equations, we get:
2(-1) - 5(2) = -12
-2 - 10 = -12, which is not true for the first equation.
And,
-(-1) + 4(2) = 9
1 + 8 = 9, which is true for the second equation.
Option D: (2, 2)
Substituting these values into the equations, we get:
2(2) - 5(2) = -12
4 - 10 = -12, which is not true for the first equation.
And,
-(2) + 4(2) = 9
-2 + 8 = 9, which is not true for the second equation.
Based on the tests we have performed, option B: {3, 3} is the only ordered pair that satisfies both equations of the given system.
