<h2>The Domain of a Relation</h2><h3>
Answer:</h3>
<h3>
Step-by-step explanation:</h3>
The Domain of a Relation is just the set of the 
values of the ordered pairs in the relation (Recall that if you have an ordered pair, 
, 
is the value).
We are given the relation: 
. The Domain of this relation is 
.
B - 3A = 2
3B - 6A = 12
(2)B - (6)A =4
3B - 6A = 12
Subtract
-B = -8
B = 8
Plugin 8 for B
8 - 3A = 2
8 = 3A + 2
6 = 3A
2 = A
(Double checking)
3(8) - 6A = 12
-6A = 12-24 = -12
- 6A = -12
Divide by -6
A= 2
It works
A = 2. B = 8. Hope this helps
46.8 because you multiply 7.80 times 6 and it gives you the answer

Define x :
----------------------------------------
Let the number be x.
----------------------------------------
Construct equation:
----------------------------------------
<span>Nine more than the product of 4 and the number is 73
</span>⇒4x + 9 = 73
----------------------------------------
Solve for x:
----------------------------------------
4x + 9 = 73
4x = 73 -9
4x = 64
x = 16
