The answer is the last option: 
Explanation:
1. You have that the equation of the line is:
Where 
is the slope of the line and 
is the intercept with the y-axis.
2. Therefore, you must find .
3. Then, you must substitute the points given in the problem and the slope into the equation of the line and solve for , as following:
2 - 0.5n= 3n+16
----------------------- subtract 2 from both sides
-2 -2
-0.5n = 3n+14
----------------------- then subtract -3n from both sides as well
-3n -3n
-3.5n = 14
--------------- divide -3.5 on each side
-3.5 -3.5
simplify
Answer: n= -4
Answer:
The time spend to burn energy is 3300 minutes .
Step-by-step explanation:
Given as :
The speed at which the bike ride = 10 miles per hours
The energy burn while riding = 550 calories
Let The time spend to burn energy = t minutes
So, According to question
Time spend = 
i.e t = 
hours
∴ t = 55 hours
So, in minutes
The time spend
1 hours = 60 min
∴ 55 hours = 60 × 55 = 3300 minutes
So, The spend to burn energy = t = 3300 minutes
Hence The time spend to burn energy is 3300 minutes . Answer

Answer:
$879.19
Step-by-step explanation:
I'm not sure how you got that, but here's what I did.
To calculate tax:
Cost before tax * Tax% = Tax
$815.95 * 7.75% = $63.24
To calculate cost after tax:
Tax + Cost before tax = Cost after tax
$63.24 + $815.95 = $879.19
