Solve for X, and graph<br> 8. - 6x + 14 &lt;-28 OR 9x + 15 &lt;- 12
son4ous [18]

For this case we must indicate the solution set of the given inequalities:

-6x + 14

Subtracting 14 from both sides of the inequality we have:

-6x

Dividing by 6 on both sides of the inequality:

-x

We multiply by -1 on both sides, taking into account that the sense of inequality changes:

x> 7

Thus, the solution is given by all values of x greater than 7.

On the other hand we have:

9x + 15

Subtracting 15 from both sides of the inequality we have:

9x

Dividing between 9 on both sides of the inequality we have:

x

Thus, the solution is given by all values of x less than -3.

Finally, the solution set is:

(-∞, - 3) U (7,∞)

Answer:

(-∞, - 3) U (7,∞)

What is the range for this set of data?<br> 7, 15, 12<br> 3<br> 05<br> O 8<br> 12
noname [10]

Solution:

<u>It should be noted:</u>

  • Range: The range of a data is a number that subtracts the smallest number from the greatest number in the data.

<u>Thus, the range of the given data set:</u>

  • 7, 15, 12

Greatest number: 15

Smallest number: 7

  • => 15 - 7 = Range
  • => 8 = Range
