Consider Functions F and G
Zanzabum

Answer:

A

Step-by-step explanation:

We are given two functions:

\displaystyle f(x)=\frac{x-16}{x^2+6x-40}\text{ and } g(x)=\frac{1}{x+10}

And we want to find:

f(x)+g(x)

Thus:

\displaystyle =\frac{x-16}{x^2+6x-40}+\frac{1}{x+10}

We can factor the denominator of the first term:

\displaystyle =\frac{x-16}{(x+10)(x-4)}+\frac{1}{x+10}

In order to add the two terms, we must have a common denominator. To achieve this, we can multiply to second term by (x - 4). Therefore:

\displaystyle =\frac{x-16}{(x+10)(x-4)}+\frac{1}{x+10}\Big(\frac{x-4}{x-4}\Big)

Multiply:

\displaystyle =\frac{x-16}{(x+10)(x-4)}+\frac{x-4}{(x+10)(x-4)}

Combine:

\displaystyle =\frac{(x-16)+(x-4)}{(x+10)(x-4)}

Simplify:

\displaystyle =\frac{2x-20}{(x+10)(x-4)}

We can expand the denominator:

\displaystyle =\frac{2x-20}{x^2+6x-40}

Therefore, our answer is A.

Last month, Claire's bank statement said that she overdrew her account. Her bank balance was -45.32−45.32minus, 45, point, 32 eu

The question is incomplete and the full version can be found online.  

Answer: Janeth has 17.92 dollars in her account.

Step-by-step explanation:

The question states that, after having been told that she overdrew her account the previous month, Claire´s new bank balance is 17.92 dollars. Having said that, the question is what does that new amount means, and the options given are that she overdrew her account by 17.92 dollars, or that she has 17.92 dollars in her account.

The answer couldn´t be that Claire overdrew her account again, by 17.92 dollars this time, because if that was the case, her new balance would be the addition of the previous -45.32 dollars plus the new -17.92 dollars:

-45.32-17.92=-63.24

This means that the new amount would be -63.24. Since the number is positive, it represents the money she has in the account: 17.92 dollars

Do you think that civilians should be targeted in warfare? Why or why not?
jasenka [17]

When countries are at war, the general rule is that civilians should not be targeted and I <u>support </u>this notion.

<h3>The Concept of War</h3>
  • War is fought by nations to assert dominance and achieve certain conditions.
  • War is fought by soldiers who pick of weapons to engage in war.

Civilians should therefore not be targeted because they have not picked up weapons to engage in the fight and so cannot be said to be targets. It makes no sense to leave the person you are fighting and who wants to fight you, to fight those who are not interested in fighting.

In conclusion, civilians should not be targeted.
