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
The answer is 20/3 first you set a variable x and 30x=200 divid both side by 30 and get the final answer
$50
20 x 2 = 40, which is 80%
and then 20 divided by 2 is 10; so you add that to 40 and you get your answer
