Answer:
D. y = { -x + 2 x ≥ 1}
{ x + 1 x < 1}
Step-by-step explanation:
First is to eliminate A and C, why?
This is because of the end points shown on the graph.
As shown, if you look at the point of (2,1) it is black, this means that not only is it closed but it is also means ≤ or ≥ symbol.
You are now left with B and D
The difference between these two is the symbols; they are facing the opposite directions.
While B says x ≤ 1, and x > 1
While D says x ≥ 1, and x < 1
The direction of the symbols depends on the direction of the lines and what is part of it (some what like a shaded area)
So you answer would be D
Answer:
4, 8, 12, 16, 24
Step-by-step explanation:
Replace the x with the x values starting at -2 and use the equation with the new x value.
E.g.
x = -2
y = 4 * -2 + 12
y = 4
Sorry if my explanation isn't the best.
Answer:
There are 12 quarters, 36 nickels and 32 dimes.
Step-by-step explanation:
A. (-3,2)
B. rt(65)
C. (x+3)^2 + (y-2)^2 = 65
we know that
The volume of a cube is equal to
where
s is the length side of the cube
solve for s
![s=\sqrt[3]{V}](https://tex.z-dn.net/?f=s%3D%5Csqrt%5B3%5D%7BV%7D)
--------> equation 
in this problem we have
substitute the value of V in the equation
![s=\sqrt[3]{2,560}\ in](https://tex.z-dn.net/?f=s%3D%5Csqrt%5B3%5D%7B2%2C560%7D%5C%20in)
therefore
<u>the answer is</u>
