When using a debit card: A:There are always fees. B:Identification is always required. C:You still need to record transactions i
Komok [63]

Answer:

D.

Step-by-step explanation:

Since this isn't a credit card, there are no interests or fees on a debit card, so A is incorrect. B is also incorrect. You only need identification when you are withdrawing or depositing at a bank, but purchases made in stores or online do not need your identification. You also don't need to record transactions in your checkbook (but it is recommend to keep track of purchases). Modern day technology already records transaction history and all you need to do is access it online.

D is correct because if someone steals your PIN for your debit card, they could go to stores and use that money. You can dispute charges and report to the bank if that happens.

Look at the attached file. <br><br> please show your work on how you got the answer
statuscvo [17]

Answer:

D

Step-by-step explanation:

\frac{f(x)}{g(x)}

= \frac{2x+4}{2x^2+4x}

Factor out 2 on the numerator and 2x on the denominator.

= \frac{2(x+2)}{2x(x+2)}

Cancel the factor (x + 2) on the numerator/ denominator

= \frac{2}{2x} ← cancel the 2 on numerator/ denominator

= \frac{1}{x} : x ≠ 0
