Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given a situation that
If an increase in one variable causes a decrease in another variable,
Then, there is inverse relationship.
When one variable is increased whereas other variable falls.
There will be inverse relationship.
Since inverse relation has negative relation.
Then, there is a negative relationship.
Hence, Option 'A' is correct.
The equation that describes the which gives the area of the pen, A, as a function of x, the length of fence parallel to the barn is A = 130x - x²
<h3>How to find area of a rectangle?</h3>
The pen is rectangular. Therefore,
area of a rectangle = lw
where
Therefore,
perimeter = 2w + l
perimeter = 2w + x
130 = 2w + x
130 - x = 2w
w = 65 - 1/ 2 x
A = xw
A = x(65 - 1/ 2 x)
A = 65x - 1 / 2 x²
Therefore, the function that represents A, the area of the pen is as follows:
A = 130x - x²

I’m very excited, I get to see my brothers so that’s fun
Answer:
(p + q)² - ∛(h·3k) or (p + q)² - ∛(h·3k)
Step-by-step explanation:
Cube root of x: ∛x
Product of h and 3k: h·3k
Sum of p and q: p + q
*****************************
From (p + q)² subtract ∛(h·3k) This becomes, symbolically:
=> (p + q)² - ∛(h·3k)
