Answer:
Yes.
The relation is a function because every element in the domain (the x's) is mapped to one element in the range (the y's).
Step-by-step explanation:
For a relation that is a set of points all you have to look for while igorning any duplicate points is that all of the x's are different. If there are any 2 (or more) x's that are the same, then it is not a function.
So there are no duplicate points.
For example the set {(1,5),(2,5)(1,5)} is really just {(1,5),(2,5)}.
Anyways the x's in the points are (in order from left to right):
1
-4
3
0
2
All of these are different, I did not list a value for x that was same anywhere in that list. So it is a function.
The relation is a function because there is no x that gets mapped to more than one y.
L= R x angle = 7 x 2 = 14
Answer:
the answer is A.
Step-by-step explanation:
to get the you would use the distributive property to multiple the 4 by the two term in the parentheses.
Answer:
4 : 1
Step-by-step explanation:
(3 days : 18 hours) this is a ratio , where both the units must be same before simplifying.
1 day = 24 hours, 3 days = (3 × 24) hours
3 days = 72 hours
Now both the units are same, so we can easily simplify now.
72 hours : 18 hours
36 : 9 = 12 : 3
= 4 : 1 ( Answer)
There are 25 acres of apple trees, and 40 acres total. Thus, the probability of him NOT finding an apple tree is 1 - (25/40) = 15/40 = 37.5% or the second choice.
