Answer:
Bus B travels faster.
Step-by-step explanation:
Bus A travels according to the equation
y = 125/2 x
This equation is in the form y = mx + b, where m = 125/2, and b = 0.
m is the slope, so the slope is 125/2 which equals 62.5
The slope is the rate of change. Since y is distance in miles, and x is time in hours, the slope is the speed in miles per hour.
The speed of Bus A is 62.5 miles per hour.
Bus B travels according to the graph. We can find the slope by using easy-to-read points on the graph. The slope is the speed in miles per hour.
Look for two points on grid line intersections since they are the easiest ones to read. Let's use point (0, 0) and point (3, 200). Now that we have 2 points, we can find the slope.
The speed of Bus 2 is 66.67 miles per hour.
Answer: Bus B travels faster.

Answer:
- Let p be the population at t be the number of years since 2011. Then,
- The projected population of the high school in 2015=1800
- In <u>2019</u> the population be 1600 students
Step-by-step explanation:
Given: The population at Bishop High School students in 2011 =2000
Also, Every year the population decreases by 50 students which implies the rate of decrease in population is constant.
So, the function is a linear function.
Let p be the population at t be the number of years since 2011.
Then,
So at t=0, p=2000
In year 2015, t=4, substitute t=4 in the above equation ,we get
Hence, the projected population of the high school in 2015=1800
Now, put p=1600 in the function , we get
Now, 2011+8=2019
Hence, in <u>2019</u> the population be 1600 students
