2 angles are Complementary, if the sum of their measures = 90°.
Let the 2 angles be A and B, and let their measures be m(A)=a, m(B)=b.
Let A be the larger angle.
"the larger angle is six more than three times the smaller angle."
can be 'translated' into algebra as: a = 6 + 3b
Also, since A and B are complementary, we have a+b=90°.
substitute a=6+3b in the second equation:
a+b=90°
(6°+3b+b)=90°
4b=90°-6°
b=84°/4=21°
Then, a = 90°-21°=69°
Answer: a= 69°, b=21°
The correct option has been marked in the Figure below. A function 
from a set 
to a set 
is a relation that assigns to each element 
in the set exactly one element 
in the set . The set is the domain (also called the set of inputs) of the function and the set contains the range (also called the set of outputs).
For our correct option we have:
<u>Set A, Domain:</u>
Inputs: -2, 1, 0, 1, 2, 3
<u>Set B, Range:</u>
Outputs: -1, 0, 1, 2, 3
This is a function because this is a relation that assigns to each element in the set exactly one element in the set . So, the assignation is as follow:
- -2 (in x) matches to 0 (in y)
- -1 (in x) matches to 3 (in y)
- 0 (in x) matches to 2 (in y)
- 1 (in x) matches to -1 (in y)
- 2 (in x) matches to 0 (in y)
- 3 (in x) matches to 2 (in y)
