Answer:
-4x^3 - 4y^2
Step-by-step explanation:
-5y^2 + 5 - 4 - 4y^2 + 5y^2 - 4x^3 - 1
= -4x^3 -4y^2
Answer:
541 (484) 783, 437 (410) 642
Step-by-step explanation:
Required
Fill in the bracket
First, we generate a formula for the first sequence: 541 (484) 783
![484 = 2 * [783 - 541]](https://tex.z-dn.net/?f=484%20%3D%202%20%2A%20%5B783%20-%20541%5D)
![484 = 2 * [242]](https://tex.z-dn.net/?f=484%20%3D%202%20%2A%20%5B242%5D)


Using the same formula for the second sequence: 437 (?) 642
![x = 2 * [642 - 437]](https://tex.z-dn.net/?f=x%20%3D%202%20%2A%20%5B642%20-%20437%5D)
Where x represents the empty bracket
![x = 2 * [205]](https://tex.z-dn.net/?f=x%20%3D%202%20%2A%20%5B205%5D)


Yes you are correct. Nice work.
(h,k) = (10,-4) is the center; r = 2 is the radius
(x-h)^2 + (y-k)^2 = r^2
(x-10)^2 + (y-(-4))^2 = 2^2
<h3>(x-10)^2 + (y+4)^2 = 4</h3>
