The center of the equation of the circle will be (h, k) = ( -3. -1).
<h3>What are a circle and its equation?</h3>
A circle can be characterized by its center's location and its radius's length.
Let the center of the considered circle be at (h,k) coordinate.
Let the radius of the circle be 'r' units.
Then, the equation of that circle would be:
![(x-h)^2 + (y-k)^2 = r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%20%2B%20%28y-k%29%5E2%20%3D%20r%5E2)
We have been given an equation of the circle as
![(x+3)^2+(y+1)^2=9](https://tex.z-dn.net/?f=%28x%2B3%29%5E2%2B%28y%2B1%29%5E2%3D9)
By comparing the equation with general equation of the circle
we get,
h = -3
k = -1
r = 3
So, the center of the equation will be (h, k) = ( -3. -1).

Answer:
9+x<12
Step-by-step explanation:
add 9 to an unknown number.
9+x
use the < less than symbol (instead of an equal sign) and write 12.
Step-by-step explanation:
<em>(-2)-(+15)=(-17)</em>
<em>the</em><em> </em><em>diffe</em><em>rence</em><em> </em><em>between</em><em> </em><em>those</em><em> </em><em>two</em><em> </em><em>temp</em><em>erature</em><em> </em><em>s</em><em> </em><em>is</em><em> </em><em>(</em><em>-</em><em>1</em><em>7</em><em>)</em>
The answer would be D: $162 because $120 x 35% or (0.35) = $42 so $120 + $42 gives you $162
