NEED HELP ASP Find the common difference of the arithmetic sequence -8, -15, -22, ...
lukranit [14]

Answer:

  -7

Step-by-step explanation:

To find the differences in a sequence, subtract the term before:

  -22 -(-15) = -7

These differences are the same, so constitute the "common" difference.

The common difference of the sequence is -7.

-10y + 18 = -3 (5y - 7) + 5y
Alecsey [184]

Answer:

-10y + 18 = -3 (5y - 7) + 5y

-10y + 18 = -18y + 21 + 5y

-10y + 18 = -13y + 21

Step-by-step explanation:

-10y + 18 = -3 (5y - 7) + 5y

-10y + 18 = -18y + 21 + 5y

-10y + 18 = -13y + 21
