Answer:

Step-by-step explanation:
A circle centered at (0,0) with radius r is 
Since your circle has diameter of 12, then its radius is 6. Then 
So a possible answer is: 
If you want to move the location of the center, but keep it on the x-axis, then add or subtract a number to the x, such as this:

The center of this circle would be (-4, 0) which is still on the x-axis.

The answer is A. Below is the solution:
w - 45 <= 5 and <span>w - 45 <= -5
</span>w <= 50 <span> w<= 40
</span><span>the the class is 40 - 50</span>
Answer:
x=9
Step-by-step explanation:
<B = <E from the concurrency statement
