Answer:

32 days

Step-by-step explanation:

Assume that the jar is full initially, containing 24 oz.  After how many withdrawals of 3/4 oz will the jar be empty?

24 - (3/4)n = 0, or

24 = (3/4)n, or 96 = 3n.  Dividing both sides by 3, we get n = 32.

The jar will be empty after 32 days.

Give the line that is parallel to the line y=-5x-2 and goes through (3,-9)
igor_vitrenko [27]

Answer: I don’t think there is such a line. A Line that passes through the point (3,-9) must have a positive slope, unlike the line y=-5x-2, which has a negative slope. If a line where to go through (3,-9), is would intersect the line you presented.
