|2x -3| < | x + 5 |, then x belongs to :
( -3, 5 )
( 5, 9 )
( -2/3, 8 )
( -8, 2/3 )
If 3 < | x | < 6, then x belongs to
( - 6, -3 ) U ( 3, 6 )
( - 6, 6 )
( -3, -3 ) U (3, 6 )
None of these
Log 2x > 4, then x belongs to
x > 4
x > 16
x > 8
Solution of 4x + 5 < 7x + 8 is
(1, ∞)
(-1, ∞)
(2, ∞)
(-2, ∞)
x2 -3 |x| + 2 < 0, then x belongs to
( 1,2 )
( -2, -1 )
( -2, -1 ) U ( 1, 2 )
If | x | < x , then:
x is a positive real number
x is a non negative real number
There is no x satisfying this inequality
x is a negative real number
If a < b then,
a/(-2 ) < b/(-2)
a/2 > b/2
1/a < 1/b
a/-2 > b/-2
If |x| > 5, then
0 < x < 5
x < -5 or x > 5
-5 < x < 5
x > 5
If a/b < c/d, then
( a/b)2 < (c/d)2
( x - 1 ) > 0
( x -2 ) > 0
(x - 2 ) < 0
( x - 1 ) > 0 if ( x -2 ) > 0
