The product of a non-zero rational number and an irrational number is irrational.
Therefore C is the answer.
A, B, and D are all properties of rational numbers. Irrational numbers are ones that can not be written as a ratio, or fraction, using whole numbers. They are non-repeating, non-terminating numbers. Example would be pi.
Answer:
Step-by-step explanation:
Use the midpoint formula:
So, the Change In X is 2-8 = -6
And the Change in Y is 7-4 = 3
Once you divide both of the changes by 2, you get
X: -3
Y:
So the midpoint is:
The values that make the denominator zero are not in the domain.
x²- 4x - 12 = 0
(x - 6)(x + 2) = 0
Answer: 6, -2
<h3>Answer:</h3>
C. 5 – (m + 3)
<h3>Explanation:</h3>
... Five decreased by ⇒ 5 - ___
... the sum of a number and three ⇒ (m+3)
So, the whole word phrase translates to ...
... 5 - (m+3) . . . . . matches selection C.
_____
"the sum of a number and 3" refers to the whole quantity (m+3), which is why we put it in parentheses. In English, the operative phrase is "five decreased by the sum", and the prepositional phrase "of a number and three" describes the content or nature of the sum.
