The absolute value of a number <em>a</em> is written as |a| . And represents the distance between a and 0 on a number line.
So, Option C. x≥ 11 or x ≤ 1 is correct answer
Inequality given is,
|x − 6| ≥ 5
Taking <em>positive case,</em>
x − 6 ≥ 5
x − 6 + 6 ≥ 5 + 6
x ≥ 11
Taking <em>negative case,</em>
x − 6 ≤ - 5
x - 6 + 6 ≤ -5 + 6
x ≤ 1
So, solution of given inequality is x ≥ 11 or x ≤ 1

Answer:
p = 3, q = 2.5
Step-by-step explanation:
Given that x = - 4 is a root of the equation, then
(- 4)² - 4p - 4 = 0, that is
16 - 4p - 4 = 0
12 - 4p = 0 ( subtract 12 from both sides )
- 4p = - 12 ( divide both sides by - 4 )
p = 3
Also given that the equation x² + px + q = 0 has equal roots
Thus the value of the discriminant b² - 4ac = 0
Here a = 1, b = p and c = q, thus
p² - 4q = 0 ← substitute p = 3 from above into the equation
9 - 4q = 0 ( subtract 9 from both sides )
- 4q = - 9 ( divide both sides by - 4 )
q = 2.5
