It's called perfect cubes
Answer:
b
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ← r is the radius
The circle shown is centred at the origin and has a radius of 5, thus
x² + y² = 5² ⇒ x² + y² = 25 → b
This is solved for all values of
y = -x-3. (Assuming you meant that 2x+2y=-6).
