Step-by-step explanation:
Answer:
<h2>x = - 3/7 or x = 1</h2>
Step-by-step explanation:
7x² - 4x - 3 = 0
Rewrite - 4x as a difference
That's
7x² - 7x + 3x - 3 = 0
Factorize the expression
7x( x - 1) + 3 ( x - 1) = 0
(7x + 3)( x - 1 ) = 0
7x + 3 = 0 x - 1 = 0
7x = - 3 x = 1
x = -3/7
The solutions are
x = - 3/7 or x = 1

Answer: Option D. 13
Solution:
The data is:
16, 6, 8, 12, 14, 14
1) Sort the data from the least to the greatest:
6, 8, 12, 14, 14, 16
2) Find the median (middle value)
6, 8, 12, 14, 14, 16
1 2 3 4 5 6
We have to middle values, the third and fourth values (12 and 14), then the median is the average of these two values:
Median=(12+14)/2
Median=(26)/2
Median=13
If 
, then by definition of absolute value
On the other hand, if 
, then
So, the overall solution to the inequality is interval union
