<h3>Given Equation:-</h3>

$\boxed{ \tt \frac{3}{x + 5} - \frac{2}{x - 3}}$

<h3>Step by step expansion:</h3>

$\dashrightarrow\sf\dfrac{3}{x + 5} - \dfrac{2}{x - 3}$

Write the equation

$\\ \\$

$\dashrightarrow\sf\dfrac{\frac{3 \times (x + 5)(x - 3)}{x + 5} - \frac{2 \times (x + 5)(x - 3)}{x - 3}}{(x + 5)(x - 3)}$

Take the lcm of the equation I.e (x + 5) (x + 3)

$\\ \\$

$\dashrightarrow\sf\dfrac{\frac{3 \times \cancel{(x + 5)}(x - 3)}{\cancel{x + 5}} - \frac{2 \times (x + 5)\cancel{(x - 3)}}{\cancel{x - 3}}}{(x + 5)(x - 3)}$

cancel like terms I.e (x + 5) with (x+ 5) and (x - 3) with (x - 3)

$\\ \\$

$\dashrightarrow\sf\dfrac{\frac{3 \times (x - 3)}{1} - \frac{2 \times (x + 5)}{1}}{(x + 5)(x - 3)}$

$\\ \\$

$\dashrightarrow\sf\dfrac{3 \times (x - 3)- 2 \times (x + 5)}{(x + 5)(x - 3)}$

Remove 1 as denominator

$\\ \\$

$\dashrightarrow\sf\dfrac{3x - 9- 2 (x + 5)}{(x + 5)(x - 3)}$

Multiply 3 with x - 9

$\\ \\$

$\dashrightarrow\sf\dfrac{3x - 9- 2 x - 10}{(x + 5)(x - 3)}$

Multiply - 2 with x + 5

$\\ \\$

$\dashrightarrow\sf\dfrac{3x - 2x- 9 - 10}{(x + 5)(x - 3)}$

Arrange the equation so that it would be easier to solve.

$\\ \\$

$\dashrightarrow\sf\dfrac{x- 9 - 10}{(x + 5)(x - 3)}$

Subtract 3x with 2x

$\\ \\$

$\dashrightarrow\bf\dfrac{x-19}{(x + 5)(x - 3)}$

Add -9 with - 10

$\\ \\$

$\therefore \underline {\textsf{\textbf{Option \red{one} is correct}}}$

Heidi is preparing for the national gymnastics competition. the table below shows the number of hours Heidi spent preparing for

galina1969 [7]

To answer the problem above, we first need to know the difference in hours.
from month 1 to 2 the difference in hour is 1.5.
Month 2 to 3 = 3.5 to 5 = 1.5
Month 3 to 4 = 5 to 6.5 = 1.5
Month 4 to 5 = 6.5 to 8 = 1.5

The answer is C. Linearly, because the table shows that hours increase by an equal factor for an equal increase in months. which is 1.5 hours per month.

6x+2y=12 solve for y,state the m and b,and graph

kramer

Move 6x to the right side: 2y=12-6x
Divide both sides by 2: y=6-3x
m is the slope which in this case is -3
To see a graph plug y=6-3x into the website wolfram alpha!
Hope this helps!!
