|2x + y - 3z|
Plug in the values
|-4 + 10 - 9|
= |-3|
= 3

The answer is (3) because when all the letters are turned into numbers then solved it becomes [-4+10+(-9)] then you have to turn it into a positive because of the lines.

Answer:

$-2\leq x < 8$

Step-by-step explanation:

Notice that the leftmost endpoint, 2, has a closed circle, which means that it is included in the inequality. Also, the rightmost endpoint, 8, has an open circle, which means that is NOT included in the inequality.

Because the inequality only includes what is between the two numbers, you write the inequality as $-2\leq x < 8$ to show that -2 is included and 8 is not included.
