All of these sets meet the requirements of the triangle inequality. The sum of any two numbers in the set is greater than the third one. (You really only need to check that the sum of the smallest two is greater than the largest.)
It can help to resolve the numbers that are only indicated as to value.
√13 ≈ 3.606
2√10 ≈ 6.325
_____
Your comparisons can be ...
2 + 3 = 5 > 3.606 . . . is a triangle
5 + 5 = 10 > 6.325 . . . . . . is a triangle
5 + 12 = 17 > 15 . . . . . . . . is a triangle
Answer:
what is the question
Step-by-step explanation:
<h2>
Answer:</h2>
We will use substitution to solve this system for x.
![x - 2y = 27\\y = 5x\\\\x - 2(5x) = 27\\\\x - 10x = 27\\\\-9x = 27\\\\x = -3](https://tex.z-dn.net/?f=x%20-%202y%20%3D%2027%5C%5Cy%20%3D%205x%5C%5C%5C%5Cx%20-%202%285x%29%20%3D%2027%5C%5C%5C%5Cx%20-%2010x%20%3D%2027%5C%5C%5C%5C-9x%20%3D%2027%5C%5C%5C%5Cx%20%3D%20-3)
Now that we know what x is, we can determine y by pluging in -3 for x in one of the original equations. I will use the first one.
![-3 - 2y = 27\\\\-2y = 30\\\\y = -15\\](https://tex.z-dn.net/?f=-3%20-%202y%20%3D%2027%5C%5C%5C%5C-2y%20%3D%2030%5C%5C%5C%5Cy%20%3D%20-15%5C%5C)
We now have our solution.
D. ![(-3, -15)](https://tex.z-dn.net/?f=%28-3%2C%20-15%29)
We can check our answer by pluging the solution into one of the original equations to see if both sides equal each other. I will use the first equation.
![-3 - 2(-15) = 27\\\\-3 + 30 = 27\\\\27 = 27](https://tex.z-dn.net/?f=-3%20-%202%28-15%29%20%3D%2027%5C%5C%5C%5C-3%20%2B%2030%20%3D%2027%5C%5C%5C%5C27%20%3D%2027)
Since the equation checks out, our solution is correct.
