Answer:

a>4

Step-by-step explanation:

-7a-11<1-4a

ADD 4a to both sides

-3a-11 <1

Add 11 to both sides

-3a <12

Divide both sides by 3

-a <4

Multiply by -1 both sides and FLIP SIGN

a>4

So a should be 5 ,6,7,8.........

On the number line you need to count from zero 4 units to the right (positive 4) Once you are in number 4 draw an open circle which means the 4 is NOT included) Draw a line from 4 to the right because it is bigger than 4.

Interval notation is (4,∞)

[ ] a square bracket when we want to include the number 4

( ) a round bracket when we don't want to include the number 4

<h2><u>ABSOLUTE VALUE</u></h2>

The absolute value of a number is the distance from 0 to that number. The distance is positive, hence, the absolute value is always a positive number.

<h3>Exercise</h3>

Replace the value of x:

$| x - 8 |$

$| -4 - 8 |$

$| -12 | = \large{\boxed{12}}$

The absolute value of a number is the numerical value of the number, without regard to its sign.
