Solve for X, please show work!
Molodets [167]

Answer:

the solution set consists of {x < -2 ∪ x > 10/3}

Step-by-step explanation:

|3x - 2| > 8 is equivalent to the following set of inequalities:

1) 3x - 2 > 8

and

2) -(3x - 2) > 8

In case 1, above, add 2 to both sides, obtaining 3x > 10, or x > 10/3.

In case 2, above, carry out the indicated multiplication first:

-3x + 2 > 8.  Next, subtract 2 from both sides:  -3x > 6.

Next, divide both sides by -3, remembering to reverse the direction of the inequality sign:  x < -2.

Thus, the solution set consists of {x < -2 ∪ x > 10/3}

\sqrt{4}  <  \sqrt{8}  <  \sqrt{9}

Thus :

2 <  \sqrt{8}  < 3

So √8 is between 2 and 3 ,

Which means option three is the correct answer.

Evaluate the expression 3 4/5x-2 1/2 for x =-10
lyudmila [28]

Answer:

The value of given expression for x = - 10  is - 81

Step-by-step explanation:

Given expression as :

3 \frac{4}{5}x - 2 \frac{1}{2}

Or, 3 +  \frac{4}{5}x  - 2 -  \frac{1}{2}

Or,  \frac{19}{5}x -  \frac{5}{2}

or,  \frac{38 x - 25}{5}

Now for  x = - 10

\frac{38\times (- 10)  - 25}{5}

Or, {38\times (- 2)  - 5}

∴ - 76 - 5

Or, - 81

Hence The value of given expression for x = - 10  is - 81  Answer
