Answer:
A (10, -9)
B (0,-9)
C (0,-1)
D (10,-1)
Step-by-step explanation:
Negate the x-coordinates of each of the vertices
Answer:
Positive is 1
Negative is-1
Step-by-step explanation:
1. (x , y) → (kx , ky) = Dilation ; similar image
2. (x , y) → (y , -x) = Rotation 90 counterclockwise ; congruent
3. (x , y) → (-x , y) = Reflection over y-axis ; congruent
4. (x , y) → (-x , -y) = Rotation 180 ; congruent
5. (x , y) → (x, -y) = Reflection over x-axis ; congruent
6. (x , y) → (-y , x) = Rotation 90 clockwise ; congruent
7. (x , y) → (x + a , y + b) = Translation ; congruent
Hope this helps :)
Capacity of the pool = 30 x 20 x 5 = 3000 ft³
Amount of water already filled = 30 x 20 x 4 = 2400 ft²
Amount of water needed to full the pool = 3000 - 2400 = 600 ft²
---------------------------------------------------------------------------------------
Answer: 600 ft² of water is needed to fill up the pool.
