Answer:
(x-3)^2+(y-4)^2=6^2
Step-by-step explanation:
(x-3)^2+(y-4)^2=6^2
The rule would be addition. (+300)
Given:
![XR=x+8](https://tex.z-dn.net/?f=%20XR%3Dx%2B8%20)
![RY=4x-10](https://tex.z-dn.net/?f=%20RY%3D4x-10%20)
Since R is the midpoint of the line, we can set XR equal to RY and solve for x.
![RY=XR](https://tex.z-dn.net/?f=%20RY%3DXR%20)
![4x-10=x+8](https://tex.z-dn.net/?f=%204x-10%3Dx%2B8%20)
![4x=x+18](https://tex.z-dn.net/?f=%204x%3Dx%2B18%20)
![3x=18](https://tex.z-dn.net/?f=%203x%3D18%20)
![x=6](https://tex.z-dn.net/?f=%20x%3D6%20)
Now we know what x is. We can plug in x to RY and XR and then add it all together to find XY. Let's find XR:
![XR=6+8](https://tex.z-dn.net/?f=%20XR%3D6%2B8%20)
![XR=14](https://tex.z-dn.net/?f=%20XR%3D14%20)
Let's find RY now:
![RY=4(6)-10](https://tex.z-dn.net/?f=%20RY%3D4%286%29-10%20)
![RY=24-10](https://tex.z-dn.net/?f=%20RY%3D24-10%20)
![RY=14](https://tex.z-dn.net/?f=%20RY%3D14%20)
Since we know that:
![XR+RY=XY](https://tex.z-dn.net/?f=%20XR%2BRY%3DXY%20)
We can plug in our answers:
![14+14=XY](https://tex.z-dn.net/?f=%2014%2B14%3DXY%20)
Final answer:
![XY=28](https://tex.z-dn.net/?f=%20XY%3D28%20)
Answer:
y = -2x - 5
Step-by-step explanation:
Set the slope of the given equation to the reciprocal to get a perpendicular slope:
y = 1/2x --> -2x
y = -2x + b will be your current equation. To get b, you must insert the given information: (-1, -3)
-3 = -2 (-1) + b
Solve:
-3 = 2 + b
<u>-2 -2 </u>
-5 = b
Thus your equation would be y = -2x - 5.
Answer:
Answer is 8 9/10
We convert 'fifths' into 'tenths'
3/5 = (x2) = 6/10
Note 7/10 is more and 10/10 =1
We can predict their will be 9/10 after we subtract and do the sum.
12 6/10 - 3 7/10 = 8 9/10
Step-by-step explanation:
We redo with decimals
12.6 - 3.7 = 8.9 = 8 9/10
