Answer:
I got 460.
Step-by-step explanation:
You multiply 115 by 4. Right?
Answer:
The length of the resulting segment is 500.
Step-by-step explanation:
Vectorially speaking, the dilation is defined by following operation:
(1)
Where:
- Center of dilation.
- Original point.
- Scale factor.
- Dilated point.
First, we proceed to determine the coordinates of the dilated segment:

![P'(x,y) = O(x,y) + k\cdot [P(x,y)-O(x,y)]](https://tex.z-dn.net/?f=P%27%28x%2Cy%29%20%3D%20O%28x%2Cy%29%20%2B%20k%5Ccdot%20%5BP%28x%2Cy%29-O%28x%2Cy%29%5D)
![P(x,y) = (0,0) +5\cdot [(10,40)-(0,0)]](https://tex.z-dn.net/?f=P%28x%2Cy%29%20%3D%20%280%2C0%29%20%2B5%5Ccdot%20%5B%2810%2C40%29-%280%2C0%29%5D)
![P'(x,y) = (50,200)](https://tex.z-dn.net/?f=P%27%28x%2Cy%29%20%3D%20%2850%2C200%29)
![Q'(x,y) = O(x,y) + k\cdot [Q(x,y)-O(x,y)]](https://tex.z-dn.net/?f=Q%27%28x%2Cy%29%20%3D%20O%28x%2Cy%29%20%2B%20k%5Ccdot%20%5BQ%28x%2Cy%29-O%28x%2Cy%29%5D)
![Q' (x,y) = (0,0) +5\cdot [(70,120)-(0,0)]](https://tex.z-dn.net/?f=Q%27%20%28x%2Cy%29%20%3D%20%280%2C0%29%20%2B5%5Ccdot%20%5B%2870%2C120%29-%280%2C0%29%5D)
![Q'(x,y) = (350, 600)](https://tex.z-dn.net/?f=Q%27%28x%2Cy%29%20%3D%20%28350%2C%20600%29)
Then, the length of the resulting segment is determined by following Pythagorean identity:
![l_{P'Q'} = \sqrt{(350-50)^{2}+(600-200)^{2}}](https://tex.z-dn.net/?f=l_%7BP%27Q%27%7D%20%3D%20%5Csqrt%7B%28350-50%29%5E%7B2%7D%2B%28600-200%29%5E%7B2%7D%7D)
![l_{P'Q'} = 500](https://tex.z-dn.net/?f=l_%7BP%27Q%27%7D%20%3D%20500)
The length of the resulting segment is 500.
...........Hope this helps :)
These angles are corresponding angles, and we know that corresponding angles are equal when a transversal intersects two parallel lines.
So,
8x - 12 = 6x + 8
=> 8x - 6x = 8 + 12
=> 2x = 20
=> x = 20/2
=> x = 10
So, the value of x is 10.
Answer:
True
Step-by-step explanation:
When we multiply exponents with the same base, we add the exponents
a^b * a^c = a^ (b+c)
