Answer:
(D). The number that is 7 to the right of 2 on the number line
Step-by-step explanation:
It could also be the number that is 2 to the right of 7 on the number line. When numbers are added, the distances of each to the origin are laid end-to-end from the origin to the right on the number line.
2+7 can mean that the distance 2 is added to the distance 7, or vice versa. (The commutative property of addition says order does not matter.)
Answer:
There is no fixed domain, meaning it is ongoing
The range is from -1 ≤ x ≤ 3
It is a function
Step-by-step explanation:
Domain refers to the x values. If there was a domain then there would be a dot or a point signalling that there is a fixed domain, however, there are arrows meaning that it will keep going.
The range refers to the y-values. The lowest y-value is -1 and the highest is 3.
It is a function because, when you do the vertical line test, each x-value has its own y-value.
Answer:
9(p + q)(9p + 9q - 1)
Step-by-step explanation:
Given
81(p + q)² - 9p - 9q ← factor out - 9 from these 2 terms
= 81(p + q)² - 9(p + q) ← factor out 9(p + q) from each term
= 9(p + q)(9(p + q) - 1)
= 9(p + q)(9p + 9q - 1)
