Answer:
C
Step-by-step explanation:
The inverse of the function would have the x-values and y-values swapped. To find the inverse of a function, the x('s) and the y('s) would be swapped. C is the only one with the x-values and the y-values swapped, and thus, is the correct answer.
I hope this helps. :)
Answer:
Speed of the plane from Washington: 
Speed of the plane from LA: 
Step-by-step explanation:
We need to remember that:

Where "d" is distance, "V" is speed and "t" is time.
Let be "w" the speed in mph of the plane from Washington and "l" the speed in mph of the plane from LA.
We know that the distance between the cities is 2700 miles and after they flied for 2 hours, the distance between them was 500 miles. Then we can write the following equation:
[Equation 1]
Since the speed of the plan from LA was 100 mph faster, we can write this equation:
[Equation 2]
The steps to solve this are:
1. Substitute the Equation 2 into the Equation 1 and solve for "w":

2. Substitute the value of "w" into the Equation 2 in order to find "l":
Answer:
B
Step-by-step explanation:
A is missing a combination AR and has repeats such as AG and GA. Since the order of the sides doesn't matter, AG and GA are the same thing.
C is missing many combinations, it only has 4
D has two of the same sides. The question states "you can choose two <em>different </em>sides" so something like AA is not an option
We can use the process of elimination to conclude the answer is B.
Answer: -0.5
<u>Step-by-step explanation:</u>
the x-value for A is 0.
the x-value for B is -2.
The total distance from A to B is -2.
= -0.5
A + -0.5
= 0 - 0.5
= -0.5
