Answer:
a(n) = -16b + (n - 1)(3b)
Step-by-step explanation:
First term is -6b.
Common difference is 3b; each new term is equal to the previous one, plus 3b.
Formula for this arithmetic sequence is
a(n) = -16b + (n - 1)(3b)
5x5=25 so 25 different ways
First, let's find how much she will need to pay without tax. She is buying 2 shirts at $21 each (which costs $42 in total) and a pair of pants for $23.50, meaning that her subtotal is:
Now, let's apply a sales tax of 8.5%. To do this, we are going to need to find the balance of the tax, which we can then add to the subtotal. The balance of the tax is:
Adding this to the subtotal, we get:
Now, we know the total cost she is going to have to pay is $71.07. Thus, using a $100 bill, she is going to have to pay:
She is going to have to pay $28.93.

x=2
x=3
2(1)-y=4
2-y=4
-2 both sides
-y=2
÷-1 both sides
y=-2
(1,-2)
2(2)-y=4
4-y=4
-4 both sides
-y=0
y=0
(2,0)
2(3)-y=4
6-y=4
-6 both sides
-y=-2
÷-1 both sides
y=2
