Answer:
Option D.
Step-by-step explanation:
The given system of equations is
...(1)
...(2)
On simplifying the second equation, we get
On dividing by -1, we get
...(3)
It is clear that equation (1) and (3) are same equations. It means equation (1) and (2) represent the equivalent equation.
So, the given system of equations has infinitely many solutions.
Therefore, the correct option is D.
Answer:
7/12
Step-by-step explanation:
1/6 +1/12+2/6
=1×2/6×2 +1/12+2×2/6×2
=2/12+1/12+4/12
final answer is
= 7/12
2 because the difference in the equation must equal 0 so it must equal 6 so 6/3 is 2. Therefore the answer is 2
The answer is C (-1,-4)
I got the answer by graphing the equation and plotting each the points down to see which one lies on the graph
