<h3>I think answer is </h3><h3>v = 176 cu ft</h3>
Answer:
???
Step-by-step explanation:
we need to know what we're supposed to do
We equate the derivative of the function to 0 to find the x-value at its minimum:
f'(x) = 4x + 28
0 = 4x + 28
x = -7
Now, we put this value into the original equation to find the minimum value:
f(-7) = -106
The function has a positive slope so it will increase. Thus, the range will be y > -106
The answer is B
Your two systems will be
8A + 3S = 79$
your 2nd will be
10A + 5S = 105$
