.3455 is the correct answer.

Two lines are parallel when their slopes are the same.
Because the arrow is pointing to the left, the answer to the solution set needs to be less than the the number the dot is on.
A solid dot on a number means that that number is included in the solution set.
In the picture the solid dot is on 4.5, so the solution set needs to be equal to or less than 4.5.
The answer is:
{x | x ≤ 4.5}
Answer:
0.35865 and 0.35867
Step-by-step explanation:
for this number, the hundreths thousandths place is
0.358659 (bolded)
so, since the 9 rounds up, the estimated number would be 0.35866
the numbers before would be 0.35865 and after, 0.35867
