So
is indeed conservative with the scalar potential function

where
is an arbitrary constant.
Answer: 800$ is the answer.
multiply to by both sides, remove 1/2.
Have a blessed day.
Answer:
C. x=42
Step-by-step explanation:
16 + 3x + y = 180
126 + 16 + y = 180
y = 38
16 + 3x + 38 = 180
54 + 3x = 180
3x = 126
x=42
