Answer:
D
Step-by-step explanation: it the line is going done the linear function is decreasing causing both negative infinity and infinity to decrease
Answer: C. 10 + 2h = 30
Step-by-step explanation:
- A does not make sense because the phone billing company would not be cutting off the money they earn while Jeremiah is on a call with someone.
- B does not make sense because the phone billing company would be charging Jeremiah a higher amount than the amount he uses while speaking on the phone.
- C makes sense because the phone billing company charges Jeremiah the total amount of his phone and $2 per hour he is on a phone call with someone.
- D does not make sense because the total is 30 not h.

Answer:
![\boxed {d = 5}](https://tex.z-dn.net/?f=%5Cboxed%20%7Bd%20%3D%205%7D)
Step-by-step explanation:
Use the <u>Distance Formula</u> to help you determine the distance between two given points:
![d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x_%7B2%7D%20-%20x_%7B1%7D%29%5E%7B2%7D%20%2B%20%28y_%7B2%7D%20-%20y_%7B1%7D%29%5E%7B2%7D%7D)
First point: ![(x_{1}, y_{1})](https://tex.z-dn.net/?f=%28x_%7B1%7D%2C%20y_%7B1%7D%29)
Second Point: ![(x_{2}, y_{2})](https://tex.z-dn.net/?f=%28x_%7B2%7D%2C%20y_%7B2%7D%29)
-Apply the two given points onto the formula:
First point: ![(1, 4)](https://tex.z-dn.net/?f=%281%2C%204%29)
Second point: ![(-2, 0)](https://tex.z-dn.net/?f=%28-2%2C%200%29)
![d = \sqrt{(-2 - 1)^{2} + (0 - 4)^{2}}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28-2%20-%201%29%5E%7B2%7D%20%2B%20%280%20-%204%29%5E%7B2%7D%7D)
-Solve for the distance:
![d = \sqrt{(-2 - 1)^{2} + (0 - 4)^{2}}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28-2%20-%201%29%5E%7B2%7D%20%2B%20%280%20-%204%29%5E%7B2%7D%7D)
![d = \sqrt{(-3)^{2} + (-4)^{2}}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28-3%29%5E%7B2%7D%20%2B%20%28-4%29%5E%7B2%7D%7D)
![d = \sqrt{9 + 16}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B9%20%2B%2016%7D)
![d = \sqrt{25}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B25%7D)
![\boxed {d = 5}](https://tex.z-dn.net/?f=%5Cboxed%20%7Bd%20%3D%205%7D)
Therefore, the distance is
