Answer:
the answer is the first one [3 -12 15 -21]
Step-by-step explanation:
Because 3 times 1 = 3, 3 times -4 = -12, 3 times 5=15, 3 times 7 = -21
because they are in order to get a negative one of them have to be a negative if they both of them where negative it would be positive.

Answer:
The statement represents the IDENTITY PROPERTY OF ADDITION.
Step-by-step explanation:
Here, the given expression is 8 + 0 = 8
IDENTITY ELEMENT : Identity element is a special type of element in a given set of system, such that any number remains UNALTERED if operated with the identity element.
⇒ a + X = X for, a ≡ IDENTITY ELEMENT
Now, 8 + 0 = 8
Comparing it with the above equation , we get
0 ≡ IDENTITY ELEMENT in the given Binary operation of Addition.
Hence, the statement represent the IDENTITY PROPERTY OF ADDITION.
Answer: x = 27, y = 23
Explanation:
x = chickens
y = horses
║ x + y = 50
║ 2x + 4y = 146
║ 2x + 2y = 100
║ 2x + 4y = 146
(2x + 4y = 146) - (2x + 2y = 100)
2y = 46
y = 23 <span> <<<<<<<< We found y ¯\_(ツ)_/¯
Sub y = 23 into </span> x + y = 50
x+ 23 = 50
x = 50 - 23
x = 27 <<<<<<<< We found x ¯\_(ツ)_/¯
