Hi!
What you'll first need to do is subtract 4 from 4 and 13. After doing so, your equation will look like this...
-3x=9
Next, you'll need to divide -3x and 9 by -3. After you've done that, you'll get...
x=-3.
So your answer would be x=-3
I hope this helps!
Answer:
5002.46412961
Step-by-step explanation:
3 x 7 because three, seven times is 21
C(h,k) radius(r)
C(2,-3) r=4
(x-h)^2 + (y-k)^2 = r^2
(x-2)^2 + (y--3)^2 = 4^2
(x-2)^2 + (y+3)^2 = 16
therefore, the answer is D
K-2 I think I'm not sure though
