distance formula
The distance formula is really just the Pythagorean Theorem in disguise. To calculate the distance AB between point A(x1,y1) and B(x2,y2) , first draw a right triangle which has the segment ¯AB as its hypotenuse. Since AC is a horizontal distance, it is just the difference between the x -coordinates: (x2−x1)
slope formula
To calculate the slope of a line you need only two points from that line, (x1, y1) and (x2, y2). The equation used to calculate the slope from two points is: On a graph, this can be represented as: There are three steps in calculating the slope of a straight line when you are not given its equation.
midpoint formula
The midpoint is halfway between the two end points: Its x value is halfway between the two x values. Its y value is halfway between the two y values.

Step-by-step explanation:
|6| - |-6|
|6| = 6
- |-6| is |-6| which is 6 and then add the - so its -6
so now we have
6 - 6 = 0
Answer:
<h2>
Bike A costs $270 and has an expected maintenance cost of $36 per year.</h2><h2 /><h3>
"Bike A is the better choice if Greg plans on owning the bike for 5 years. Bike B is the better choice if Greg plans on owning the bike for 6 years."</h3>
Step-by-step explanation:
270-36x
there are 5 years so x=5
270 + 36(5) = 270 + 180 = <u>450</u>
If it were 6 years than x = 6
270 + 36(6) = 270 + 216 = <u>486</u>
Bike B:
360 + 20x
For option b x = 5
360 + 20(5) = 360 + 100 = 460
for option b it would be 6 years than x = 6
360 + 20(6) = 360 + 120 = <u>480</u>
