The slope is rise over run. The ski run drops 5, so it would be -5, and the horizontal change of 20 would be the run, so you'd get -5 over 20 then you divide both by 5 and you get your answer of -1 over 4.
(2x+6)/10 = (x+6)/8
10(x+6) = 8(2x+6)
10x + 60 = 16x + 48
6x = 12
x = 2
so
AE = 2(2) +6
AE = 4 + 6
AE = 10
10(x+6) = 8(2x+6)
10x + 60 = 16x + 48
6x = 12
x = 2
so
AE = 2(2) +6
AE = 4 + 6
AE = 10
Answer:
A∩B={}
B is a proper subset of A:
B⊂A
Step-by-step explanation:
A∩B means the intersection of the set A and the set B. In other words, is the set of elements contained in these both sets.
Given the set A and the set B:
{
}
{
}
You can indentify that the numbers common in both sets are: 25,45 and 65.
Therefore you get:
A∩B={}
Since all elements of B are in A, and A contains elements that are not in B, then B is a proper subset of A:
B⊂A
