(11/x^2-25)+(4/x+5)= 3/x-5

Ierofanga [76]

$\bf \textit{difference of squares}
\\ \quad \\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-------------------------------\\\\
\cfrac{11}{x^2-25}+\cfrac{4}{x+5}=\cfrac{3}{x-5}\implies \cfrac{11}{x^2-5^2}+\cfrac{4}{x+5}=\cfrac{3}{x-5}$

$\bf \cfrac{11}{(x-5)(x+5)}+\cfrac{4}{x+5}=\cfrac{3}{x-5}\impliedby 
\begin{array}{llll}
\textit{notice, LCD is }(x-5)(x+5)\\
\textit{so let's multiply all by it}\\
\textit{to toss the denominators}
\end{array}$

$\bf (x-5)(x+5)\left( \cfrac{11}{(x-5)(x+5)}+\cfrac{4}{x+5} \right)=(x-5)(x+5)\left( \cfrac{3}{x-5} \right)
\\\\\\
11+4(x-5)=3(x+5)\implies 11+4x-20=3x+15
\\\\\\
4x-9=3x+15\implies x=24$

What is 18.5% of 500?<br> 9.25<br> 92.5<br> 925<br> 0.925

Lady bird [3.3K]

Answer:

92.5

Step-by-step explanation:

$\frac{18.5}{100} = \frac{x}{500}$

cross multiply:

18.5 · 500 = 9250

100 · x = 100x

isolate x by dividing 100 from both sides:

x = 92.5

hope this helps!

Given the points (4,-2) and (8,1), what is the equation of a line that connect the two points. Answer in slope-intercept form.

monitta

The equation of required line in slope-intercept form is:

$y=\frac{3}{4}x-5$

Step-by-step explanation:

We are given the points (4,-2) and (8,1) we need to find the equation of a line that connect the two points. We need to find equation of line in slope-intercept form.

The standard equation of slope-intercept form is:

$y=mx+b$
