b
a and d should not be considered bc it is not logically correct. c is eliminated because that may not always be the case. therefore it should be b.
800/100 = 8
800 is 100 times as much as 8
Answer:
- A-B=7x-3x+10-4x²-66+4
- 4x-52-4x²

First, rewrite the equation in standard form.
The center-radius form of the circle equation<span> is in the format:
(x – h)^</span>2<span> + (y – k)^</span>2<span> = r^</span>2
<span>with the center being at the </span>point<span> (h, k) and the radius being "r".
</span>
(x-3)^2 + (y+4)^2 = 81
From here, you can determine the center and radius. The center is at (3,-4) and the radius is 9.
