Solve the absolute value inequality.<br><br> |2x - 3| &gt; 7
s344n2d4d5 [400]

Hi!

<u><em>NOTE: When solving absolute value inequalities, > or ≥ means OR, and < and ≤ means AND.</em></u>

<u><em /></u>

|2x - 3| > 7

Since the absolute value is isolated, we can now solve.

First, remove absolute value signs, then solve for x.

2x - 3 > 7

2x > 10

x > 5

Now, we have to solve again, but this time we flip the inequality sign and switch positive 7 to a negative 7, like so:

2x - 3 < -7

2x < -4

x < -2

Now, as stated above, since it's a greater than symbol it means OR.

<u><em>x > 5 OR x < -2</em></u>

<u><em></em></u>

Please help!!! ill mark brainliest

3x - 1 = 3x + 1  

subtract 3x from both sides to get (-1 = 1).  This is a false statement so it is: CONTRADICTION

************************************************

4x - 11 = 7

add 11 to both sides and then divide both sides by 4 to get (x = \frac{18}{4} = \frac{9}{2}).  This statement is true only when x = \frac{9}{2} so it is: CONDITIONAL

*************************************************

2 - 8x = 2 - 8x

add 8x to both sides to get (2 = 2).  This is a true statement so it is: IDENTITY

*************************************************

x + 1 = -x + 4

add x to both sides, subtract 1 from both sides, and divide both sides by 2 to get  (x = \frac{3}{2} ). This statement is true only when x = \frac{3}{2} so it is: CONDITIONAL

Answer: B, A, C, A
