Answer:
91 + 125 + 92 +(3x-5) + (4x- 8)= 540
308 +3x -5 +4x -8 =540
7x - 295 = 540
7x = 540 -295
7x = 245
x = 245/7
x = 35

Answer:
-2x - 28
Step-by-step explanation:
-4(x+6) +2 (x-2) Distribute the -4 to (x+6) and the 2 to (x-2):
-4x - 24 + 2x - 4 Combine like terms -4 + 2x and -24-4:
-2x - 28
Hope this helped :)
We have the following function:
p (x) = - 2 (x-9) ^ 2 +200
We derive to find the maximum of the function:
p '(x) = - 4 (x-9)
Rewriting:
p '(x) = - 4x + 36
We match zero:
-4x + 36 = 0
We clear x
x = 36/4
x = 9 degrees
The maximum population occurs when x = 9.
We evaluate the function for this value:
p (9) = - 2 * (9-9) ^ 2 +200
p (9) = 200
Answer:
The maximum number of fish is:
p (9) = 200
