A). |x| = |-x|
This is always true.
The definition of 'absolute' value is 'size of the number without its sign'.
That's what this expression says.
b). |x| = -|x|
This is never true, because an absolute value is never negative.
This one would true if x=0 . So maybe some people might say
it's sometimes true, but that doesn't feel right to me. I say never.
c). |-x| = -|x|
This looks to me like exactly the same situation as (b),
and I would say all the same things about it.
I think it is true but I am not 100% sure thought but good luck

Answer: The company must sold 382 units to break even.
Step-by-step explanation:
Hi, there is no question asked, so I suppose that you need to find the number of items (x) to break even.
To answer this question we have to equal both sides of the equations:
Since costs equal its income:
C=R
So:
38x +19100= 88x
Solving for x
19100= 88x-38x
19100=50x
19100/50 =x
382=x
The company must sold 382 units to break even.
