Answer:
(-∞, -12), (2, ∞)
or
(-∞, -12) U (2, ∞)
Step-by-step explanation:
|3x + 15| > 21, |3x + 15| < -21
3x + 15 > 21, 3x + 15 < - 21
-15 -15 -15 -15
------------------ -------------------
3x > 6 3x < - 36
÷3 ÷3 ÷3 ÷3
------------ ------------------
x > 2 x < -12
(-∞, -12), (2, ∞)
or
(-∞, -12) U (2, ∞)
I hope this helps!

The ending balance after the transactions is; $59.25
<h3>How
to determine ending balance</h3>
To determine the ending balance after a number of transactions;
- Let money inflow and balance be represented as positive.
- Let money outflow be represented as negative.
Therefore; Since starting balance is; $822.67; we have;
- <em>$822.67 + $227.45 - $600.00 + $50 - $100 - $200 - $3.50 - $2.50 - $134.87.</em>
The ending balance on the account is therefore; $59.25
