Solve the inequality algebraically. Write the solution in interval notation.<br> |9x + 10| < 15

viva [34]

The given inequality is

$| 9x+ 10 |$

First we need to remove the absolute sign , and when we do so , we will get a compound inequality, that is

$-15< 9x+10 < 15$

To solve for x, first we need to get rid of 10. and for that, we have to do subtraction

$-15-10$

Now we need to get rid of 9, and for that, we do division

$\frac{-25}{9}< x< \frac{5}{9}$

So the required solution is

$( \frac{-25}{9} , \frac{5}{9})$

Find the slope of the line passing through (-4,6) and (10,8)

muminat

Answer:

1/7

Step-by-step explanation:

In order to determine the slope, we must find the change in y over the change in x:

$\frac{y_{2}-y_{1} }{x_{2}-x_{1} } = \frac{8-6}{10--4}$ = 2/14= 1/7.

Therefore, the slope between these two points is 1/7.
