The ordered pair (-4,0) is the solution to the system of equations because it makes both equations true.
Further explanation:
Given equations are:
Given point is:
(-4,0)
In order to check whether the point makes equations true, we have to put the point in equations.
So, putting (-4,0) in first equation:
Putting (-4,0) in second equation
We can see that the given point makes both the equations true.
Hence, the ordered pair (-4,0) is the solution to the system of equations because it makes both equations true.

Answer:
x ∈ {-26, 22}
Step-by-step explanation:
A graph shows that the points (-26, -27) and (22, -27) lie on a circle of radius 40 centered at (-2, 5). That is, if Q is either one of these points, the vector PQ will have a length of 40:
- √((-26-(-2))^2 +(-27-5)^2) = √((-24)^2 +(-32)^2) = √1600 = 40
- √((22 -(-2))^2 +(-27 -5)^2) = √(24^2 +(-32)^2) = √1600 = 40
You can call it -40 if you like, but you have to define what negative length means when you do that.
