Solve the inequality algebraically. Write the solution in interval notation.<br> |9x + 10| &lt; 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})

Simply by using rationalize denominators.<br><br> 2a^-1/2
Advocard [28]
Pemdas, so exponent before multiply
so do a^-1/2 then multiply it by 2

remember that x^ \frac{m}{n}= \sqrt[n]{x^m} and
x^{-m}= \frac{1}{x^m}
therefor, a^ \frac{-1}{2}= \frac{1}{a^ \frac{1}{2} } = \frac{1}{ \sqrt{a} }
the we multiply by 2

\frac{2}{ \sqrt{a} }

A water container holds 2 liters. How many
EastWind [94]

Number of containers for 2 litres of water = 1

So, number of containers for 1 litre of water = ½

So, number of containers for 30 litres of water

= ½ × 30

= 30/2

= 15

So, 15 of these containers would be needed to fill a 30-liter drum.
