The coordinate is an ordered pair
. We have a number, 5, for y, which we can substitute (plug-in) for y in the equation of the line and solve for x.
I think the answer is A, I could be wrong though
First we pick the equation. Let's say we pick first one. From it we express y.
Then we use this y and plug it in instead of y in the second equation.
Now just solve for x.
We plug this x in the first equation.
And solve for y.
So the solution to the equation is geometrically a point P which lies on the intersection of the two lines.
Hope this helps.

Answer:
8
Step-by-step explanation:
Given
- Triangle XYZ is congruent with Triangle MNL
If 2 Triangles are congruent(≅) then all the corresponding angles and sides are equal
⇒
- XY=MN
- YZ=NL
- XZ=ML
- ∠X=∠M
- ∠Y=∠N
- ∠Z=∠L
Therefore asked to find XY
The corresponding edge is MN and its length is given=8
Therefore XY=8
Answer:
C ( h(x) = x^2 - 6x)
Step-by-step explanation:
Assuming that the function has a slope of 1 (none of the answer choices show a different slope, for all of the coefficients of x^2 are 1) the easiest way to solve this problem would be to find the function for the graph instead of inputting points from the graph into each of the function. (you could do that if you weren't sure.) To get a function from the graph, we first have to find the vertex and enter it into this vertex form function:
h(x) = (x - a )^2 - b
(there are other ways, but finding the vertex and putting the function in vertex form and then simplifying is the easiest way in this situation.) Looking at the graph, we can tell that the vertex of the function is (3, -9). Using the fact that h(x) = (x - a )^2 - b works for the vertex (-a, b), we can conclude that the function is
h(x) = (x - 3)^2 - 9.
This is not an answer! We have to simplify (x - 3)^2 - 9 to answer the question. By squaring x - 3, we get:
x^2 - 6x + 9 - 9 =
x^2 - 6x.
Therefore, the answer is:
C (h(x) = x^2 - 6x).
