Answer:
Step-by-step explanation:
Harvey rides his bike at an average speed of 12 miles in 1 hour, 24 miles in 2 hours, and so on. Let h be the number of hours he rides and d be distance traveled. Write the equation for the relationship between distance and time in point-slope form.
----
You have three points relating time and distance:
(1,12),(2,24),(3,36)
-----
The slope for your equation would be (24-12)/(2-1) = 12/1 = 12
-------------------------------
The intercept is the distance you would travel in no time; that would be zero.
---------------------------------
The equation is: distance = 12(time)
d = 12t
Answer: 75.4
Step-by-step explanation:
The equation for the circumference for a circle is diameter times pi. 24 times pi is 75.3982236862. Rounded to the nearest tenth would make it 75.4.

Answer:
24 hours
Step-by-step explanation:
It appears that the score (s) is related to the number of hours (h) by ...
s = 30 +(10/4)h
So, for a score of 90, the number of study hours needs to be ...
90 = 30 +2.5h
60 = 2.5h
60/2.5 = h = 24
Jesse needs to study 24 hours to get a score of 90.
