Answer:
Step-by-step explanation:
2x - 3y = 14
<u>x + 3y = -11 </u> Add the functions
3x + 0y = 3 ----> x=1
2(1) - 3y = 14
2 - 3y = 14
-3y = 12
y = -4
Answer:
AC = 22
Step-by-step explanation:
Given that B is the midpoint of AC , then AB = BC , that is
2x + 1 = 5x - 14 ( subtract 2x from both sides )
1 = 3x - 14 ( add 14 to both sides )
15 = 3x ( divide both sides by 3 )
5 = x
Thus
AC = AB + BC = 2x + 1 + 5x - 14 = 7x - 13 = 7(5) - 13 = 35 - 13 = 22
The answer is x2 + 2xy + y2.
Answer:
or ![4\sqrt{5}](https://tex.z-dn.net/?f=4%5Csqrt%7B5%7D)
Step-by-step explanation:
Using the distance formula:
![d=\sqrt{(7-(-1))^2+(6-2)^2}=\sqrt{8^2+4^2}=\sqrt{64+16}=\sqrt{80}=4\sqrt{5}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%287-%28-1%29%29%5E2%2B%286-2%29%5E2%7D%3D%5Csqrt%7B8%5E2%2B4%5E2%7D%3D%5Csqrt%7B64%2B16%7D%3D%5Csqrt%7B80%7D%3D4%5Csqrt%7B5%7D)
Hope this helps!
