Find the diffrence of the following sequence : -7,-9,-11

-2

Step-by-step explanation:

you're subtracting 2 from each to get the next number, so the answer is -2

hope this helps, have a wonderful day :))

x ≤ - 2

Step-by-step explanation:

Given the inequality :

3x+5≤−1

Subtract 5 from both sides

3x + 5 - 5 ≤ - 1 - 5

3x ≤ - 6

Divide both sides by 3

3x/3 ≤ - 6/3

x ≤ - 2

Mr.Choe's error was that he changed the inequality sign. The inequality sign in this case does not need to be changed.
