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

<h3>How to graph the set on a number line?</h3>
The set is given as:
(−∞, 0) ∪ [2, 8]
The above means that the numbers inclusive in the set are:
- (−∞, 0): All real numbers less than 0
- [2, 8]: All real numbers between 2 and 8 (inclusive)
This means that there will be a gap on the number line between 0 and 2 and from 8 till positive infinity
Having done the above illustration, next we plot the set on a number line

Answer:
Step-by-step explanation:
(-1,-2) , (3,10)
slope(m) = (10 - (-2) / (3 - (-1) = (10 + 2) / (3 + 1) = 12/4 = 3
y = mx + b
slope(m) = 3
u can use either of ur points....
(3,10)....x = 3 and y = 10
sub into the formula and find b, the y int
10 = 3(3) + b
10 = 9 + b
10 - 9 = b
1 = b
so ur equation is : y = 3x + 1
