Answer: The system of equations have many solutions and the correct options are A,B and D.
Explanation:
The given equations are,
..... (1)
.... (2)
Simplify the second equation.
![3y+6x=15](https://tex.z-dn.net/?f=3y%2B6x%3D15)
![3(y+2x)=15](https://tex.z-dn.net/?f=3%28y%2B2x%29%3D15)
Divide both sides by 3.
![2x+y=5](https://tex.z-dn.net/?f=2x%2By%3D5)
It is same as equation (1). Since equation (1) and (2) are same, therefore all the points lies on the line or which satisfies the equation are the solution of the given system of equations.
Test the points whether the point lies on the line or not.
Check for point A(6,-7).
![2(6)+(-7)=5](https://tex.z-dn.net/?f=2%286%29%2B%28-7%29%3D5)
![5=5](https://tex.z-dn.net/?f=5%3D5)
LHS and RHS are equal, therefore the point A is the solution of the system of equations.
Check for point B(2,1).
![2(2)+(1)=5](https://tex.z-dn.net/?f=2%282%29%2B%281%29%3D5)
![5=5](https://tex.z-dn.net/?f=5%3D5)
LHS and RHS are equal, therefore the point B is the solution of the system of equations.
Check for point C(-2,-9).
![2(-2)+(-9)=5](https://tex.z-dn.net/?f=2%28-2%29%2B%28-9%29%3D5)
![-13=5](https://tex.z-dn.net/?f=-13%3D5)
LHS and RHS are not equal, therefore the point C is not the solution of the system of equations.
Check for point D(-4,13).
![2(-4)+(13)=5](https://tex.z-dn.net/?f=2%28-4%29%2B%2813%29%3D5)
![5=5](https://tex.z-dn.net/?f=5%3D5)
LHS and RHS are equal, therefore the point D is the solution of the system of equations.
Therefore the options A,B and D are correct.
Answer:
A. AB congruent to DC

I just took the test and got it correct.
Hope this helps!!! PLZ MARK BRAINLIEST!!!
Supplement=angles that add to 180
so x+y=180
one is 65
65+x=180
subtract 65 from both sides
x=115
the supplelmemnt is 115 degrees
