Answer:
A: 2+27=29
B: The sum of the integers 2 and 27 is the integer 29, which demonstrates that integers are closed under addition.
Step-by-step explanation:
Since, closed property of addition for a set A is defined as,
∀ x, y ∈ A ⇒ x + y ∈ A,
∵ Set of integer is closed under multiplication,
If Z represents the set of integer,
Then 2, 27 ∈ Z ⇒ 2 + 27 = 29 ∈ Z,
Hence, the equation illustrates given statement,
2+27 = 29
The statement that correctly explains given statement,
The sum of the integers 2 and 27 is the integer 29, which demonstrates that integers are closed under addition.c
Answer:
The total change in value of her shares is $300
Step-by-step explanation:
Given that each share went up by $10 and she has 30 shares then the total change in the value of her shares is the product of the change in the price of each share and the total number of shares she has
= $10 * 30
= $300
Yes, it is a function because each input has only one output.

19. There are 24 hours in a day and Maria travelled for 15 days so multiply the two:
24*15=360
So Maria travelled for 360 hours.
