Question

Which two inequalities can be written to solve the absolute value inequality?

|4x-1|≤19

Question 5 options:

4x-1≥-19 and 4x-1≤19


4x-1≥-19 or 4x-1≤19


4x-1≥19 and 4x-1≤19


4x-1≥19 or 4x-1≤19

Answer 1

Answer:| 4x - 1 | < = 19

if it is less then, u set it up like this...

-19 < = 4x - 1 < = 19

so ur 2 inequalities are :

4x - 1 > = -19 and 4x - 1 < = 19......it is not OR....because if it is less then, it is AND...but if it was greater then, it would be OR

ur answer is A

Explanation:

Answer 2

| 4x - 1 | < = 19

if it is less then, u set it up like this...
-19 < = 4x - 1 < = 19
so ur 2 inequalities are :
4x - 1 > = -19 and 4x - 1 < = 19......it is not OR....because if it is less then, it is AND...but if it was greater then, it would be OR

ur answer is A
