distance (d) = rate (r) x time (t)
Nell: d = 12(2.5) = 30 miles
Kristen: d = 14(2.5) = 35 miles
Kristen - Nell = distance apart
35 - 30
5
Answer: 5 miles apart
Answer:
1. Yes it does. It's a function because it pass in the vertical line test, which tell us that if you can draw an vertical line through the graph and this line touches the graph in only one point, it is a function.
2. B. I and II only
3. A. y = 8/7 x +5
A. After the mod. One wall is “x” longer than original (horizontal in diagram) and the other is “x” shorter (vertical)
(30+x)(30-x)
b. He original area = 30 x 30 = 900 sq. ft.
The mod. Area is (30+6)(30-6) = 36x24= 764 sq. ft.
So the room was largest to begin with when it was a square
34½% = 34.5% = 0.345 = 345/1000 = 69/200
