Answer:
37.5 miles per hour
Step-by-step explanation:
The question might be trying to confuse the reader. Point (1) which states the difference in weight does not show any evidence on how it affects the speed of both cyclist. Point (2) show an important point where the distance traveled is 75 miles.
Cyclist B, who leave point X at 2pm overtook cyclist A at 4pm, showing that the time it took for B to overtook A is 2 hours
Speed = distance / time
= 75 miles / 2 hours
= 37.5 miles per hour
Answer: 
{
}
Step-by-step explanation:
We know that, by definition, the Domain is the set of all the x-coordinates of the ordered pairs and the Range is the set of all the y-coordinates of the ordered pairs.
Therefore, given 
, you can observe that the set of all second elements of ordered pairs (the values of "y") is the following:
{
}
Therefore, we can conclude that if , then the range is:
{}
Answer: C) 4. Explanation: Since the rate is constant, you can find the y coordinate by simplifying the given coordinates. Image that the graph is (week, height), which means that the given points are (3, 12) and (5, 20). Put these into a fraction, and simplify them to get x as 1. y/x = 12/3 = 4, and 20/5 = 4. Since the rates are consistent with 4 when simplified to get the x variable to 1, that means that the y coordinate of (1, y) is 4.
