Slope of AB
m = (y2 - y1)/(x2 - x1)
m = (11 - (-4))/(2 - (-1))
m = (11 + 4)/(2 + 1)
m = 15/3
m = 5
The slope of line AB is 5
Slope of CD
m = (y2 - y1)/(x2 - x1)
m = (10 - 1)/(4 - 1)
m = 9/3
m = 3
The slope of CD is 3
Since the two slopes are not equal, this means the lines are not parallel.
Since (slope of AB)*(slope of CD) = 5*3 = 15 is not equal to -1, this means the lines are not perpendicular
Answer: Neither (not parallel; not perpendicular)
Answer:butt
Step-by-step explanation:
Answer:
Volume of a cylinder is PI * radius^2 * height
height = 10 mm and radius = 3
Volume = 3.14 * 3^2 * 10mm
Volume = 282.6 cubic millimeters

Answer:
The answer would be 'D'. 2 x 12 + 5h
Step-by-step explanation:
In this case, you know that Bradley mows two lawns and for every lawn, he charges $12. If you were not given the number of lawns mowed, you would've had something like 12x with 12 representing the charge for every lawn mowed and x representing the actual amount of lawns mowed. However, since you were given the amount of lawned mowed (2) you can put 12(2) or 12 x 2 instead of 12x.
With this, you can eliminate every answer that does not include 12 x2 or 2 x 12. (You can eliminate answers A and B)
Now for the number of hours for the bushes trimmed. The same rules apply to this.
The variable (h) would be included here since we were not given the information on how many hours it took. 5 represents the amount that he charges for every hour and h is the unknown amount. However, if we were also given the info for this like let's say 3 hours, it would be 5(3) instead of 5x. But that's a different story.
So with this let's combine the two terms. You have 2 x 12 and 5h so, in the end, you have: 2 × 12 + 5h
I hope my explanation wasn't too confusing. I tried my best to put it in simple terms
