Not a function because of the vertical line test.
Domain is [-2,∞] since the left most point is -2 and the right is unbounded.
Range is (-∞,∞) since it is not bounded in terms of y.
"Population density" refers to how many people there are in a given state per square mile of area.
Look at Wyoming. This state has a total population of 522,000 people, spread over an area of 97,818 square miles.
All you have to do is to divide 522,000 people by 97,818 square miles. Your final units of measurement must be "people per square mile."
Answer:
17 5/12 lb total
Step-by-step explanation:
Find the total weight of the materials recycled:
7 2/3 lb + 9 3/4 lb
Here the LCD is 12. (Both 3 and 4 divide evenly into 12.)
Rewriting 7 2/3 lb + 9 3/4 lb with the LCD 12, we get:
7 8/12 lb + 9 9/12 lb, or 16 17/12 lb.
The fraction here must be reduced. We get
17 5/12 lb total (Recognize that 17/12 = 1 5/12.)
Answer:
−14x+3
Step-by-step explanation:
Combine Like Terms:
20x+5.5+−34x+−2.5
(20x+−34x)+(5.5+−2.5)
= −14x+3
32/24 as a mixed number is 1 1/3
