Answer and Step-by-step explanation:
Charlotte reads 4 books each week
b = number of books she reads each week
w = number of weeks that she reads
The number of books depends on the number of weeks, so
independent variable: w
dependent variable: b
b = 4w
╔═══╦═════════╦════╗
║ w ║ b = 4w ║ b ║
╠═══╬═════════╬════╣
║ 0 ║ b = 4*0 ║ 0 ║
╠═══╬═════════╬════╣
║ 1 ║ b = 4*1 ║ 4 ║
╠═══╬═════════╬════╣
║ 2 ║ b = 4*2 ║ 8 ║
╠═══╬═════════╬════╣
║ 3 ║ b = 4*3 ║ 12 ║
╠═══╬═════════╬════╣
║ 4 ║ b = 4*4 ║ 16 ║
╠═══╬═════════╬════╣
║ 5 ║ b = 4*5 ║ 20 ║

Lets rule some out off the bat, shall we?
The first one you mentioned, a circle is a plane figure with no straight sides... I can name another shape with no straight sides... an oval.
The second one you mentioned, is a true statement
The third one you mentioned, a circle is from a point, not a line segment.
The last one mentioned is also a true statement.
Answer:
--9x^3+12x^2-x-2
Step-by-step explanation:
(2-3x)(3x^2-2x-1)
6x^2-4x-2-9x^3+6x^2+3x
-9x^3+6x^2+6x^2+3x-4x-2
-9x^3+12x^2-x-2
Answer:
C. 8 miles per hour
Step-by-step explanation:
It takes Diego 
of an hour to complete the lap = x 1 hour = hour
Distance of the track = 1 mile long
The speed of an object expresses the ratio of distance moved to time taken to cover the distance.
i.e speed = 
= 
= 8
Speed = 8 mile per hour
Therefore, Diego's bike has a speed of 8 miles per hour.
Hey there!
-9 - (-4 1/3)
= -9 - (-13/3)
= -9 + 13/3
= -14/3
= -4 2/3
Therefore, your answer is: -14/3 or -4 2/3 either should work because both of the numbers are equivalent to each other
Good luck on your assignment and enjoy your day!
