The possible values of x are given by x+8=&lt;6.<br><br>The greatest possible value of 7x is_____​
kozerog [31]

Answer:

The possible values of x is given by x\leq  -2 and they include: -2, -3, -4, -5, -6 and so on

The greatest possible value of 7x is -14

Step-by-step explanation:

We are given the equation: x + 8 <= 6

Let collect the like terms:

x + 8 \leq  6\\x\leq  6 -8\\x \leq  -2

Therefore, x <= -2 and the possible values include: -2, -3, -4, -5, -6 and so on

To find the greatest possible value of 7x is when x = -2.

7x = 7 * -2\\7x = -14\\.

Answer:

recursive: f(0) = 7; f(n) = f(n-1) -8

explicit: f(n) = 7 -8n

Step-by-step explanation:

The sequence is an arithmetic sequence with first term 7 and common difference -8. Since you're numbering the terms starting with n=0, the generic case will be ...

recursive: f(0) = first term; f(n) = f(n-1) + common difference

explicit: f(n) = first term + n·(common difference)

To get the answer above, fill in the first term and common difference values.
