The side lengths of a triangle are 9, 12, and 15. Is this a right triang
O A. Yes, because 9² + 12² > 15².
O B. No, because 9 + 12 ‡ 15.
OC. Yes, because 9² + 12² = 15².
OD. No, because 9² + 12² # 15².
Answer is the A
Answer:
5 x 4 + 2 - 3 / 1

This took me so much tries to do but got it. Hope it helps! :)
Answer:
Step 1:
To find ordered pair solutions, you could create an x and y graph and fill out the x side. Then, plug in an x number to get your y number and graph the ordered pairs to see if they give you a straight line. I'm going to use these numbers: -1, 0, 1, and 2.

![\left[\begin{array}{ccc}-1&?\\0&?\\1&?\\2&?\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-1%26%3F%5C%5C0%26%3F%5C%5C1%26%3F%5C%5C2%26%3F%5Cend%7Barray%7D%5Cright%5D)
Now, let's plug in -1 into the equation first to see what we get for y.

-5 is our y if x was -1.
We do the same for the other three numbers.



Step 2:
With all that done, we can now fill out our table and graph the points.

![\left[\begin{array}{ccc}-1&-5\\0&3\\1&11\\2&19\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-1%26-5%5C%5C0%263%5C%5C1%2611%5C%5C2%2619%5Cend%7Barray%7D%5Cright%5D)
If you graph these points on graph paper / a graphing website, you will see that these points go in a straight line. If you are given an ordered pair already (for example: (3,5)), then all you have to do is plug in the x into the equation (3) and see if the outcome is true (5).

Since they don't equal each other, then (3,5) is false.
Here is the graph for the table above. I hope I helped you!
