Ответ:
C. and
Step-by-step explanation:
We are given the graph of the system of equations given by,
.
After simplifying the equations, we get,
i.e. i.e. i.e.
And,
i.e. i.e. or
Hence, we get the system of equations,
and
Now, we will check the point of intersection of the new equations,
Multiplying first equation by 7 and second equation by 2 and then subtracting both equations,
We get,
gives i.e. y = -3
So, 2x-4y=0 gives 2x-4×(-3)=0 i.e. 2x=-12 i.e. x= -6
Thus, the intersection point is (-6,-3).
So, the new system of equation matches the graph.
Hence, option C is correct.
