<span>For this case we have the following expression:
</span>

<span> We are going to make the following change of variables:
</span>

<span>Rewriting the expression we have:
</span>

<span>Factoring the expression we have:
</span>

<span>Canceling similar terms we have:
</span>

<span>Returning the change we have:
</span>

<span> The resctrictions of the function are those that make the denominator equal to zero.
We have then:
</span>

<span>
Answer: The simplified expression is: </span>
<span>
The restrictions are: </span>
28 - 2.2x = 11.6x - 54.8
28 + 54.8 = 11.6x + 2.2x
82.8 = 13.8x
82.8 / 13.8 = x
6 = x
or x = 6
My guess would be less than $25
Answer:
-25
Step-by-step explanation:
You begin with -40, then decrease by 20 so your new value is -60, then increase by 35 so your final value is -25m... hope this helps (:
