Answer:

x=6.111....

Step-by-step explanation:

x-5=0.1(x+5)

distribute 0.1 into (x+5)

x-5=0.1x+0.5

subtract 0.1x on both sides

x-0.1x-5=0.5

combine like terms

0.9x-5=0.5

add -5 on both sides

0.9x=5.5

divide both sides by 0.9

$\frac{0.9x}{0.9} =\frac{5.5}{0.9}$

x=55/9 or 6.11111.......

Line AB contains points A(-6,1) and B(1,4).

Free_Kalibri [48]

To solve this problem you must apply the proccedure shown below:

1- You have that the equation of the line is:

$y=mx+b$

Where $m$ is the slope and $b$ is the y-intercept.

2- Based on the information given in the problem, the lines $AB$ and $CD$ are parallel, which means that both have the same slope. Therefore, you can calculate the slope of $AB$ :

$m=\frac{y2-y1}{x2-x1}$

$m=\frac{4-1}{1-(-6)}=\frac{3}{7}$

3- Use the coordinates of the point $D(7,2)$ to calculate the y-intercept:

$2=\frac{3}{7}(7)+b$

4. Solve for $b$ :

$b=2-3=-1$

5. The equation of the line $CD$ is:

$y=\frac{3}{7}x-1$

The answer is: $y=\frac{3}{7}x-1$
