Is (4,-2) the solution of the system of equations shown below? 2X+4Y=-2. -4X+Y=-14. Anders: yes, no, they are the same line

No

Step-by-step explanation:

Given

Required

Is (4,-2) a possible solution?

In (4,-2)

Substitute and in:

Open all brackets

The above expression shows that (4,-2) is not a solution and there is no need to check for the second equation.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
