It’s not b or d so it’s either a or c. Hope this helped
Answer:
hope this helps you
option B
Step-by-step explanation:
ecf-zutd-cpt.
A: From the graph, car B was traveling faster.
Because the line of car B is more steep than the line of car A.
B:
The lines cross at (2,80), this means that the two cars were traveling at the same distance (80 miles) at the same time (2 hours).
C:
Since the line passes through the points (0,0) and (2,80)
So the unit rate or slope is 40 mph.
The distance which car A traveled in the first four hours = 4x40= 160 mph

Answer:
Distance between the school and the theater =
units
Step-by-step explanation:
Use distance formula to calculate the distance from the school (8, 7) and the theater (2, 3):
![d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%28x_2%20-%20x_1%29%5E2%20%2B%20%28y_2%20-%20y_1%29%5E2%7D%20)
Let,
![school (8, 7) = (x_1, y_1)](https://tex.z-dn.net/?f=%20school%20%288%2C%207%29%20%3D%20%28x_1%2C%20y_1%29%20)
![theater (2, 3) = (x_2, y_2)](https://tex.z-dn.net/?f=%20theater%20%282%2C%203%29%20%3D%20%28x_2%2C%20y_2%29%20)
Plug in the values into the distance formula
![d = \sqrt{(2 - 8)^2 + (3 - 7)^2}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%282%20-%208%29%5E2%20%2B%20%283%20-%207%29%5E2%7D%20)
![d = \sqrt{(-6)^2 + (-4)^2}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%28-6%29%5E2%20%2B%20%28-4%29%5E2%7D%20)
![d = \sqrt{36 + 16} = \sqrt{52}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B36%20%2B%2016%7D%20%3D%20%5Csqrt%7B52%7D%20)
Simplify
![d = \sqrt{4 \times 13}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B4%20%5Ctimes%2013%7D%20)
![d = 2\sqrt{13}](https://tex.z-dn.net/?f=%20d%20%3D%202%5Csqrt%7B13%7D%20)
