Answer:
D
Step-by-step explanation:
Which is x < -3
Answer:
The correct answer is E.
Step-by-step explanation:
First I look for the relationships between the coefficients. The first term corresponds to the base value.
The second term corresponds to the value obtained when the density of the underlying material is doubled and the daily usage of the equipment is halved.
With the I get the ratio of coefficients of 
:
= 8
= 64
Now I calculate the percentage increase in the useful life of the equipment as:
% = 
* %100 = %800
Answer: You can't. Read explanation.
Step-by-step explanation:
You can't subtract an expression from an equation. If you said something like subtract 8b-ab+7a from 3a-9ab+b that would work, but not here.
Let's just assume You mean it as 8b-ab-7a, then (3a-9ab+b)-(8b-ab-7a) = -8ab + 10a - 7b.

Answer:
$3, $11
Step-by-step explanation:
The profit function P(x) will be zero when either of its factors is zero. The left factor (x-3) is zero when x=3. The right factor (x-11) is zero when x=11.
Prices of $3 or $11 will result in $0 annual profit.
_____
<em>Additional comment</em>
A price halfway between these values, at (3+11)/2 = 7, will produce maximum profit, $32 million.
