You can do this by comparing your equation to the general form of equation of a circle
( x - a)^2 + (y - b)^2 = r^2 where (a,b) is the centre and r = radius:-
(x + 9)^2 (y + 6)^2 = 9
so (a,b) = (-9,-6) and r = 3
so the answer is B
Answer:
2. trust me.. i did it before.
Year New flowers
1 1200
2 300
3 75
There were 1200 wildflowers in the first year that the park started tracking them. Since then, there have been one fourth as many new flowers each year
Initially there are 1200 flowers and start decreasing by 
So first term is 1200 and common ratio is
.
Its a geometric sequence so summation becomes
i =1∑ ∞ 1200(
Now we find the sum
We use sum formula

Where a is the first term , a= 1200
r is the common ratio , r= 1/4


Sum = 1600 wildflowers
All work is show in the picture below.
There are many times in algebra when you need to simplify an expression. understanding of these properties to make the problems in algebra easier to Pour 12 ounces of coffee into mug, then add splash of milk.
following ways:
Pour 12 ounces of coffee into mug, then add splash of milk.
Add a splash of milk to mug, then add 12 ounces of coffee.
The order that you add ingredients does not matter. In the same way, it does not matter whether you put on your left shoe or right shoe first before heading out to work. As long as you are wearing both shoes when you leave your house, you are on the right track!
