Answer:
d. (4,3,6,2)
Step-by-step explanation:
The list of <em>second numbers</em> of the ordered pairs is the <em>range</em>.
___
The second number of the first pair is 4; the second number of the second pair is 3. The only 4-number answer choice containing these two numbers is (d). You don't even have to work the whole problem to make the proper choice.
Elimination because u could multiply the second equation by -3 which would cancel the x and allow you to solve for y and then everntually x but yea elimination is the best method
It is non proportional because it doesn’t go through the origin I am pretty sure

Answer:
The m∠ U is 72°.
Step-by-step explanation:
Given:
![\angle S = 90\\\angle T = 2x\\\angle U = x\\\angle V = 2x\\\angle W = 90\\](https://tex.z-dn.net/?f=%5Cangle%20S%20%3D%2090%5C%5C%5Cangle%20T%20%3D%202x%5C%5C%5Cangle%20U%20%3D%20x%5C%5C%5Cangle%20V%20%3D%202x%5C%5C%5Cangle%20W%20%3D%2090%5C%5C)
To find :
![\angle U = x = ?](https://tex.z-dn.net/?f=%5Cangle%20U%20%3D%20x%20%3D%20%3F)
Solution:
The sum of the measures of the interior angles of a polygon with 'n' sides is given as
![\textrm{sum of the measures of angle of a polygon with 'n' sides} = (n - 1)\times 180](https://tex.z-dn.net/?f=%5Ctextrm%7Bsum%20of%20the%20measures%20of%20angle%20of%20a%20polygon%20with%20%27n%27%20sides%7D%20%3D%20%28n%20-%201%29%5Ctimes%20180)
Here we have n = 5 on substituting the values we get
![\angle S +\angle T + \angle U +\angle V + \angle W = (5 -2)\times 180\\90 + 2x + x + 2x + 90 = 3\times 180\\5x + 180 = 540\\5x = 540-180\\5x = 360\\x = \frac{360}{5}\\x = 72](https://tex.z-dn.net/?f=%5Cangle%20S%20%2B%5Cangle%20T%20%2B%20%5Cangle%20U%20%2B%5Cangle%20V%20%2B%20%5Cangle%20W%20%3D%20%285%20-2%29%5Ctimes%20180%5C%5C90%20%2B%202x%20%2B%20x%20%2B%202x%20%2B%2090%20%3D%203%5Ctimes%20180%5C%5C5x%20%2B%20180%20%3D%20540%5C%5C5x%20%3D%20540-180%5C%5C5x%20%3D%20360%5C%5Cx%20%3D%20%5Cfrac%7B360%7D%7B5%7D%5C%5Cx%20%3D%2072)
Therefore,
m∠ U is 72°.
