Hello,
6b) (i) As you can see, in the first year the price drops from 27,000 to 17,000. (Look at year 0-1 on the x axis). To find the percentage drop, find the difference between the two values and divide it over the initial value of 27,000.
So, the percentage drop in the first year is:
(27000-17000) / (27000) = 0.37, or a 37% drop
The answer is 37%.
(ii) For this question, we basically have the same process as the previous question except for the second year.
From year 1 to year 2, the value starts at 17,000 and ends at 15,000.
To find the percentage drop, we do:
(17000 - 15000) / (17000) = 0.118 ≈ 0.12, or a 12% drop
The answer is 12%.
6c) To find the percentage depreciation over the first 5 years, we look at the initial value (x = 0) and the value after 5 years (x = 5), and use these values in the same percentage formula we have been using.
The initial value of the car is 27,000, and after 5 years the value is 8,000.
This is a percentage drop of (27000 - 8000) / (27000) = 0.70, or a 70% drop.
The answer is 70%.
Hope this helps!

Answer: b
Step-by-step explanation:
you start with 0 min- equals 24
1 min- 21
2 min- 18
3 min- 15
4 min- 12
5 min- 9
and so on- you look for the table that best describes that. x represents the minutes, and y represent the amount of water left in the sink.
Answer:
[See Below]
Step-by-step explanation:
✦ Turn fractions into decimals:
- (We will do something different for
and
.)
✦ Divide:
÷ 
- (Since the denominators are multiplies of each other we can divide them without having to change them into decimals.)
✦ Simplified Equation:
✦ Add:
✦ Subtract:
- (Subtraction rule is if there is 2 negatives next to each other in a problem it turns into a positive.)
✦ So your answer would be:

(Mixed Number Form)
(Decimal Form)

Answer:
=8x^3+27
Step-by-step explanation:
First you are going to multply 2x by all of the other numbers in the 2nd parentheses, then do the same with 3. By doing this you should get and answer then combine like terms.
