Given:
The length of the candle remaining unburned, in inches, can be modeled by the equation
where, t represents the number of hours since the candle was lit.
To find:
The slope and its interpretation in the context of the problem.
Solution:
Slope intercept form of a linear function is
where, m is slope and b is y-intercept or initial value.
We have,
It can be written as
The coefficient of t is -1. So, using slope intercept form the slope of this equation is -1.
Here, -1 means length of the candle remaining unburned is decreasing at the rate of 1 inch per hour.
Answer:
nth term = 18 - 3n
Step-by-step explanation:
nth term = a + (n - 1)d
a1 = 15
d = -3
nth term = a + (n - 1)d
= 15 + (n - 1)-3
= 15 + (-3n + 3)
= 15 - 3n + 3
= 18 - 3n
nth term = 18 - 3n
For instance, if you want to find the 10th term
nth term = 18 - 3n
10th term = 18 - 3(10)
= 18 - 30
= -12
10th term = -12

Asumming that 3/5 is the number of miles Jennifer has gone in 1/5 of an hour. We can take 60 (# of minutes in an hour) divided by 5, which equals 12. So 3/5 is 36 minutes. to figure out how many 1/5 are in 8 miles we would take 8 times 5 which is 40. We would then take 3 times 8, which is 24. 40 - 24 = 16. So 16 times 5 = 80 minutes. 80 divided by 60 (# of minutes in an hour) is 1 hour and 20 minutes. So it takes Jennifer 1 hour and 20 minutes to travel 8 miles.
