Answer:
f(x) = -3x + 12
Step-by-step explanation:
The chart could be represented like this:
x y
0 12
1 9
2 6
3 3
Suppose that f(x) = y
And substitute x values.
y = -3x + 12
"x = 0"
y = -3(0) + 12
y = 0 + 12
y = 12
"x = 3"
y = -3(3) + 12
y = -9 + 12
y = 3
From the results, it corresponds to the function.
I may be wrong but I’m pretty sure his normal weight was 880kg before he gained the 88kg.
Using the perimeter of a rectangle, it is found that she can make a deck of 122 ft wide.
<h3>What is the perimeter of a rectangle?</h3>
The perimeter of a rectangle of length l and width w is given by:
![P = 2(l + w)](https://tex.z-dn.net/?f=P%20%3D%202%28l%20%2B%20w%29)
In this problem:
- She has enough wood to build a deck that is 280ft, hence P = 280.
- The length is of 10 feet, hence l = 10.
- Considering that the deck's width will be added to the actual width of 8 feet, we have that w = 8 + w.
Then:
![P = 2(l + w)](https://tex.z-dn.net/?f=P%20%3D%202%28l%20%2B%20w%29)
![280 = 2(10 + 8 + w)](https://tex.z-dn.net/?f=280%20%3D%202%2810%20%2B%208%20%2B%20w%29)
![36 + 2w = 280](https://tex.z-dn.net/?f=36%20%2B%202w%20%3D%20280)
![2w = 244](https://tex.z-dn.net/?f=2w%20%3D%20244)
![w = \frac{144}{2}](https://tex.z-dn.net/?f=w%20%3D%20%5Cfrac%7B144%7D%7B2%7D)
![w = 122](https://tex.z-dn.net/?f=w%20%3D%20122)
She can make a deck of 122 ft wide.
