Answer:
(50,55,60,....)
Step-by-step explanation:
Given that a health insurance plan has a $50 enrollment fee and a copayment of $5 for each doctor visit.
The function f(x) = 5x + 50 gives the cost of x doctor visits
Here x is the no of visits.
No of visits is an independent variable while f(x) total cost is a dependent variable on x
slope = 5 which indicates for each visit extra, extra cost is 5 dollars
Enrollment fee = 50 = fixed cost
Hence domain would be
x =0,1,2,3.....
So range is
(50,55,60,....)
The slope-intercept form: y= mx + b
m - slope
b - y-intercept
The formula of a slope:
We have the points (6, 2) and (5, 5). Substitute:
Therefore we have y = -3x + b.
Put the coordinates of the point (5, 5) to the equation:
5 = -3(5) + b
5 = -15 + b <em>add 15 to both sides</em>
20 = b
<h3>Answer: y = -3x + 20</h3>
Time = distance / speed
Time = 180,000 meters / 40 m/s
Time = 4,500 seconds
1 minute = 60 seconds:
4,500 seconds / 60 seconds/minute = 75 minutes
1 hour = 60 minutes
75 - 60 = 15
The train traveled for 1 hour and 15 minutes.
