The graph of which of the following inequalities has open circles on -8 and 2 with a line segment between them
2 answers:
Answer:
Option C is correct answer.
Step-by-step explanation:
since -8 and 2 are end points with open circle therefore
If l x -a l < R
means -R< x-a< R
-R+a<x <a+R
Comparing it with -8<x<2 gives
a-R= -8
a+R= 2
Adding both ,we get 2a = -6 which equals a =-3
plugging the value a =-3 in equation a+R=2
-3+R=2 gives R =5
therefore the inequality is lx-(-3) l < 5
on simplifying we get
l x+3< 5
Option C is the correct answer
A. Can NOT be true since the absolute value will be greater than 0.
B. Does NOT work with the solutions -8 and 2.
C.√ Correct
|-8+3| = 5
|2+3| = 5
