A1 = first term = 8
<u>Plug in a1 = 8:</u>
an = 8 + (n - 1)d
<u>FInd d:</u>
Given that a2 = 5
5 = 8 + (2-1)d
5 = 8 + d
d = -3
<u>Plug in d = -3:</u>
an = 8 -3(n - 1)
Answer: an = 8 -3(n - 1) ; <span>n ≥ 1</span>

Answer:
y=-2
Step-by-step explanation:
because it's parallel --> a=-2
therefore we have y=-2x+b
the line goes through the point (3,-6) --> (-2).3+b=-6 --> b=0
Answer: 
Step-by-step explanation:
We can make the conversion from mixed numbers to improper fractions:
- Multiply the whole number part by the denominator of the fraction.
- Add the numerator of the fraction and the product obtained (This sum will be the new numerator).
- The denominator is the same.
Then:

We need to add the fractions in order to calculate the amount of paint Darren bought. Since the denominators are differente, we must find the Least Common Denominator (LCD):

Then:

To convert this improper fraction to a mixed number:
- When you divide 73 by 12 you get a quotient of 6. This will be the whole number.
- The remainder obtained is 1. This will be the numerator of the fraction.
- The denominator does not change.
Then:
