Answers

Answer:

Not arithmetic

Step-by-step explanation:

Arithmetic sequences go up by the same number or down by the same number.

From 4 to 7 thats up by 3

From 7 to 9 that's up by 2

Conclusion: not arithmetic

Answer:

The sequence is not an arithmetic sequence.

Step-by-step explanation:

7 is getting added by 2 to get 9

9 is getting added by 2 to get 11

11 is getting added by 1 to get 12

As you can see, the sequence is not consistent. Therefore, it is not an arithmetic sequence.

Answers

Answer:

k > 24

Step-by-step explanation:

To solve an inequality you must isolate the variable. Do this by using the properties of equality, specifically the property of multiplication. To get k by itself multiply both sides by 4. This way k > 24. Then, you can check your answer by plugging in any number less than or equal to 24 and solving to see if it's true.

Answer:

k = 24

Step-by-step explanation:

k is greater than or equal to 24 and 4/4 = 1 so if k is greater than or equal to 24 than that could be 24/4 and that would equal 6. that is the answer to your question.
