The correct answer is:
C) You have to pay interest on credit cards but not on charge cards.
Explanation:
A charge card is a card in which you are required to pay the balance in full every month. Because of this, there is no charge that accrues from month to month, so there is nothing to charge interest on.

Explanation:
Assumption: None of the siblings are in that class.
Original numbers
25 students with 3 siblings each gives
25
×
3
=
75
siblings
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
New numbers
1 new student takes the total students to 25+1 = 26
The new total siblings is
75
+
8
=
83
The new average is

B: (10 - 5i) + (5 - 10i) = (5 - 10i) +(10 – 5i)
C: (5+ 10i)+(- 5 - 10i) = 0+ Oi
D: [(0 - 5i)+(5-i)] +(5 +i) = (0 - 5i)+[(5 - i) +(5+i)]
1b) Which of the following demonstrates the commutative property of multiplication?
A: (8+6i)(4+2i)=(4+2i)(8+6i)
B: (7-6i)(0+2i)=(7+2i)(0-6i)
C: (2+8i)(2-8i)=20
D: (-5+3i)(-1+i)=(5-3i)(1+i)
Answer:
The answer to 1a is B and the answer to 1b) is A.
Step-by-step explanation:
I got my answer right on the quiz. So, it's actually a lot easier than it seems. Imagine 4+2=2+4 or (8)(4)=(4)(8). That is commutative property of addition and multiplication just simper. In this case B and A are the same thing just with complex numbers.
b. Neither effectively nor efficiently
c. Efficiently, but not effectively
d. Both effectively and efficiently
