Answer:
Step-by-step explanation:
Use the distance formula for coordinate geoemetry and the fact that x1 = 3, y1 = 5, x2 = 6 and y2 = 8 to fill in the formula:
![d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E2%2B%28y_%7B2%7D-y_%7B1%7D%29%5E2%20%20%20%20%7D)
fills in accordingly:
![d=\sqrt{(6-3)^2+(8-5)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%286-3%29%5E2%2B%288-5%29%5E2%7D)
which simplifies a bit to
![d=\sqrt{(3)^2+(3)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%283%29%5E2%2B%283%29%5E2%7D)
which is
![d=\sqrt{18}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B18%7D)
The square root of 18 simplifies down to
, which is 4.2426 in decimal form
15·0.8 + x = 30·0.9 --> x = 15
C. is the correct answer
Answer:
Yes, the answer would be 3835
Step-by-step explanation:
34515 divided by 9 is simply 3835
Sure, each of the following lines.
8x-6+3x-1
11x-6-1
and, 11x-7
They are both equal I think C.
