The domain of a relation is the set of all the x-terms of the relation.
Let's look at an example.
In the image provided I have attached a relation and we want to list the domain.
So, I will list all the x-terms. Notice however that I listed 7 once even though it appears twice in the relation. When listing the domain, you don't repeat the x-terms.
Answer:
x = 3
Step-by-step explanation:
Given the equation :
6x + 5=9x - 4
Collect like terms :
6x - 9x = - 4 - 5
-3x = - 9
Divide both sides by - 3
-3x / - 3 = - 9 / - 3
x = 3
Hence, x = 3
Answer:
x = 45
Step-by-step explanation:
Each corner of the square is a right angle measuring 90 degrees.
x + 45 = 90
x = 45
