Answer:
<h2>The missing value is 3, and the coordinates are (3,3).</h2>
Step-by-step explanation:
The complete question is
![y=4x-9](https://tex.z-dn.net/?f=y%3D4x-9)
Complete the missing value in the solution to the equation. (3, ? )
By given, we know that
, because coordinates are written like
.
Then, we replace the given coordinate to find
.
![y=4x-9\\y=4(3)-9\\y=12-9\\y=3](https://tex.z-dn.net/?f=y%3D4x-9%5C%5Cy%3D4%283%29-9%5C%5Cy%3D12-9%5C%5Cy%3D3)
Therefore, the missing value is 3, and the coordinates are (3,3).

Answer:
<u>The exponential model is: Cost after n years = 400 * (1 + 0.02)ⁿ</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Cost of the TV set in 1999 = US$ 400
Annual increase rate = 2% = 0.02
2. Write an exponential model to represent this data.
Cost after n years = Cost in 1999 * (1 + r)ⁿ
where r = 0.02 and n = the number of years since 1999
Replacing with the real values for 2020, we have:
Cost after 21 years = 400 * (1 + 0.02)²¹
Cost after 21 years = 400 * 1.5157
Cost after 21 years = $ 606.28
The TV set costs $ 606.28 in 2020.
<u>The exponential model is: Cost after n years = 400 * (1 + 0.02)ⁿ</u>
I think the answer is A and C!
