Answer:
5r + 2
Step-by-step explanation:
9r-5r+2+r=5r+2
\mathrm{Group\:like\:terms}
=9r-5r+r+2
\mathrm{Add\:similar\:elements:}\:9r-5r+r=5r
=5r+2
Answer: The correct option is
(D) The sequence is not arithmetic because the terms do not have a common difference.
Step-by-step explanation: We are given to select the true statement regarding the sequence that is graphed in the figure.
From the graph, we see that some of the points are (1, 1), (2, 4), (3, 9), (4, 16), (5, 25).
That is, if we write the graphed points in terms of a sequence <a(n)>, then we get
The sequence <a(n)> will be arithmetic if the difference between the consecutive terms is equal. That is, the terms should have a common difference.
Now,
This implies that the terms do not have a common difference and so the graphed function does not represent an arithmetic sequence.
Thus, the sequence is not arithmetic because the terms do not have a common difference.
Option (D) is CORRECT.
Answer:
The answer to this question is simply 6.
Step-by-step explanation:
You just need to subtract 6 from 36 to get the product of 5x6 which is 30
The consult must make at least 600 dollars. That means the combination of reviews and new written pieces must be at least $600, or greater than or equal to (<span>≥) $600.
You are also told that each new piece = $120 and each review = $60. Let's use variables n = new piece and r = review. (You might be given different variables for your answer choices). That means the total money made from a combination of new pieces and reviews is:
120n (money made from each new piece times n number of new pieces) + 60r (money made from each review times r number of reviews).
Put that all together to get your inequality:
120n + 60r </span>≥ 600
-----
Answer: 120n + 60r ≥ 600
