Hello from MrBillDoesMath!
Answer:
The first choice, Pi + (-Pi) = 0
Discussion:
Pi is an irrational number. Saying the irrational numbers <u>are</u> closed under addition means if we add two irrational numbers we will get another irrational number. In our case, Pi + (-Pi) = 0, which is correct, BUT 0 is a <u>rational </u>number. This shows the set of irrational numbers is NOT closed under addition.
Thank you,
MrB

Answer: The required set-builder notation is :
Step-by-step explanation: We are given to write the following set B in set-builder form :
the set B consists of all natural numbers less than or equal to 100.
In set-builder form, a variable x is used to represent each and every element of the set.
Therefore, the set B in set-builder form can be written as :
Thus, the required set-builder notation is :
When simplified, it should be 13/14
Answer:
t = 11/4
Step-by-step explanation:
Step 1: Write out equation
4t - 2 = 9
Step 2: Add 2 on both sides
4t = 11
Step 3: Divide both sides by 4
t = 11/4
