Step-by-step explanation:
"identity" means an operation that does nothing.
For adding numbers, adding 0 changes nothing, so 0 is the identity for addition.
For multiplication, multiplying by 1 changes nothing, so 1 is the identity for multiplication.
Is this a rise over run question
B is your answer bc 2 times 4 is 8 plus 2 minus 6 is
Answer: D' is (-8,4)
Step-by-step explanation: The rule for reflection y=x is (x,y)>( y,x) So when relecting over the axis y=x the x cordinate and the y cordinate switch places.
To solve, first let’s define regrouping:<span>
<span>=> Regrouping involves carrying and borrowing during subtraction and addition of the given numbers.
So let us have the non-regrouping decimal number:
=> 8.4
Next, the other regrouping decimal
=> 5.7
So now let us show how it becomes 14.1:
8.4
+5.7
14.1
Starting from the right, 4 + 7 is equal 11, so bring down 1 and carry 1. Now 8+5 = 13, but 13 + carry 1 = 14
<span>Thus, the answer is 14.1</span></span></span>
