Given two reference points, we want to answer some questions, the answers are:
- a) The 0 should represent the surface of the water of the pool.
- b) The slide is 12 ft above the zero (12ft above the surface of the water)
- c) She should mark the pole with a -4 on the number line.
So we start with two reference points:
- -8, which represents the depth of water in the swimming pool.
- 12, which represents the height of the slide at the pool.
So positive numbers represent height, negative ones represent depth.
A) Here the 0 should represent the surface of the water of the pool.
B) on this situation, we should see that the slide is at 12, meaning that is 12 ft above the surface of the water in the pool.
C) The pole is at a depth of 4 ft, and 0 represents the surface, then -4 will represent the depth of the pole when it is at a depth of 4 ft. She must mark the level of the pole as a -4 on the number line.

Answer:
On a coordinate plane, a step graph has horizontal segments that are each 1 unit long. The left end of each segment is a closed circle. The right end of each segment is an open circle. The left-most segment goes from (negative 3, negative 5) to (negative 2, negative 5). Each segment is 1 unit higher and 1 unit farther to the right than the previous segment. The right-most segment goes from (4, 2) to (5, 2).
Step-by-step explanation:
The floor function graphs as horizontal segments 1 unit long, each 1 unit up from the segment to its left. It will have a closed circle at the left end of the segment, and an open circle at the right end.
Since 2 is subtracted from the floor of the x-value, the closed circle at the left end of the segment will have coordinates (x, x-2). The only offered choice meeting that condition is the 3rd choice listed here.
Answer:
Apartment 1 is his best option
Answer:
B
Step-by-step explanation:
The question want three different shapes in a key.
You get the same shapes if you try and cut B key, which the question doesn't want.
