Answer:
Step-by-step explanation:
Here are the steps to follow when solving absolute value inequalities:
Isolate the absolute value expression on the left side of the inequality.
If the number on the other side of the inequality sign is negative, your equation either has no solution or all real numbers as solutions.
If your problem has a greater than sign (your problem now says that an absolute value is greater than a number), then set up an "or" compound inequality that looks like this:
(quantity inside absolute value) < -(number on other side)
OR
(quantity inside absolute value) > (number on other side)
The same setup is used for a ³ sign.
If your absolute value is less than a number, then set up a three-part compound inequality that looks like this:
-(number on other side) < (quantity inside absolute value) < (number on other side)
The same setup is used for a £ sign
Answer:
x equals 2
Step-by-step explanation:
.3-.2+.3 is .4
.4 divided by .2 is 2

Answer:
B, C E and F
Step-by-step explanation:
The inequality is x > -30
the numbers belonging to the solution are all on the heavy line.
Note -30 is not included because of the clear circle on -30
also -44 is not on the heavy line.
