Answer:
<em>D</em>
Step-by-step explanation:
I tried all the other equations by plugging in numbers and disproving their accuracy. <u>D was the only one that worked.</u>
Answer:
1/4
Step-by-step explanation:
2 1/8 - 1 7/8
Borrow 1 from the 2 in the form of 8/8
1 + 8/8+1/8 - 1 7/8
1 9/8 - 1 7/8
2/8
Simplify
1/4
Answer:
(8a + 2b − 4) and (3b − 5)
Remove bracket,
8a + 2b - 4 + 3b - 5
Group like terms,
8a + 2b + 3b - 9
Add similar elements,
8a + 5b - 9
The distance from
![(h, k)](https://tex.z-dn.net/?f=%28h%2C%20k%29)
to
![x=1](https://tex.z-dn.net/?f=x%3D1)
is
![1-h](https://tex.z-dn.net/?f=1-h)
To reflect across the line, we go twice this distance, which is
![2-2h](https://tex.z-dn.net/?f=2-2h)
So the new x-coordinate is
![h+(2-2h)=2-h](https://tex.z-dn.net/?f=h%2B%282-2h%29%3D2-h)
![A (-8, -6)](https://tex.z-dn.net/?f=A%20%28-8%2C%20-6%29)
becomes
![A' (2-(-8), -6)=(10, -6)](https://tex.z-dn.net/?f=A%27%20%282-%28-8%29%2C%20-6%29%3D%2810%2C%20-6%29)
![B (-2, -6)](https://tex.z-dn.net/?f=B%20%28-2%2C%20-6%29)
becomes
![B' (2-(-2), -6)=(4, -6)](https://tex.z-dn.net/?f=B%27%20%282-%28-2%29%2C%20-6%29%3D%284%2C%20-6%29)
![C (-5, -4)](https://tex.z-dn.net/?f=C%20%28-5%2C%20-4%29)
becomes
