We are given:
To simplify this inequality, we can add 2 to all three sides. When we do that, we are left with:
After we simplify that, we can divide all sides by -6. Here is what we get:
When you simplify, your final answer will be:
(1/2)x + 4 is the expression
Step-by-step explanation:

Answer: x= -32/5 and y=16/5
Hope this helps!
For maximum area, we take first derivative and then equalize it to zero
<span>A(x) = 27x- x^2 </span>
<span>A'(x) = 27 - 2x </span>
<span>Set that equal to zero and solve for x : </span>
<span>27 - 2x = 0 </span>
<span>27 = 2x ......................... [ added 2x to both sides ] </span>
<span>13.5 = x ........................ [ divided both sides by 2 ] </span>
So the area will be
<span>A = 27(13.5) - (13.5)^2 </span>
<span> = 364.5 - 182.25 </span>
<span> = 182.3 ft^2 </span>
