l+w=20000
l=w+4000
w+4000+w=20000
2w+4000=20000
2w=16000
w=8000
l = 8000 +4000 = 12000
William scored 8000, Luca scored 12000
Answer:

Step-by-step explanation:
All the absolute value functions given in the option are of the form:
, where (h,k) is the vertex
From your description the absolute value graph has vertex at (-4,-2)
Hence h=-4 and k=-2.
We substitute to get:

We simplify to get:
