Answer:

(a+b,c)

Step-by-step explanation:

Note that the midpoint formula is:

$(\frac{x_{1} +x_{2}}{2}, \frac{y_{1} +y_{2}}{2})$

Point A (0,0) and Point C (2a+2b,2c)

It follows that:

$(\frac{(2a+2b +0}{2}, \frac{2c+0}{2})\\(\frac{(2(a+b)}{2}, \frac{2c}{2})\\\\(a+b,c)$

Answer:

Hello

Step-by-step explanation:

The domain is limited with 2 lines parallel: -1 ≤ x ≤ 1

and the disk ? (inside of a circle) of center (0,0) and radius 2

$dom\ f(x,y)=\{(x,y) \in \mathbb{R} ^2 | \ -1\leq x \leq -1\ and \ ( -\sqrt{4-x^2} \leq \ y \leq \sqrt{4-x^2}\ ) \ \}\\$
