What is the numeratorfor the following rational expretion? 3/k+4/k=?/k

grin007 [14]

Because they all have the same denominator, all you have to do is add the numerator! So, 3/k + 4/k would equal 7/k

the equation that models the problem is 3.95m+8.95b=47.65, where m is the number of magazines and b is the number of books

Brut [27]

Based on the calculations, the number of books that were bought by Hugh are 4 books.

<h3>How to calculate the number of books?</h3>

In order to determine the number of books that were bought by Hugh, we would substitute the value of the number of magazines into the given equation and then evaluate as follows:

3.95m + 8.95b = 47.65

3.95(3) + 8.95b = 47.65

11.85 + 8.95b = 47.65

8.95b = 47.65 - 11.85

8.95b = 35.8

b = 35.8/8.95

b = 4.

In conclusion, the number of books that were bought by Hugh are 4 books.

<h2><u>Answer:</u></h2><h2> $\boxed{\boxed{y=\frac{3}{x-6}-6}}$ </h2><h2 /><h2><u>Solution Steps:</u></h2>

______________________________

<h3>1.) Substitute x, y, and general form using the formulas:</h3>

Formula for x: $x=d=6$

Formula for y: $y=k=-6$

Formula for general form y: $y=\frac{a}{x-d}+k=y=\frac{3}{x-6}+(-6)$

Note:

<em> - When doing problems like this, it's best to list out each formula and do the drag down method, and replace methods rather than doing it the entire mathematical way, as doing it that way takes a long time and it's more confusing than it should be.</em>

<u>Equation at the end of Step 1:</u>

$y=\frac{3}{x-6}+(-6)$

<h3>2.) Simplify the d and k forms:</h3>

$y=\frac{3}{x-6}+(-6)=y=\frac{3}{x-6}-6$

<em> - The x(d) stays the same since the 6 was positive and we plugged it in making it negative, so it doesn't need to be changed. (Another way to know if you need to change it is if the original </em> $(d)$ <em> or </em> $(k)$ <em> when plugged in, you had to put them in parenthesis then most likely it needs to be changed. </em>

<em> - The y(k) changes from </em> $+(-6)$ <em> to </em> $-6$ <em> because when a </em> $(+)$ <em> and </em> $(-)$ <em> are next to each other, the rule is </em> $+$ <em>. The Minus always wins in this type of problem situation.</em>
