show on three seperate number lines the following sets
(1)
a = {x l -2 < x < 5, x E R}
B = {x l 6 - 2x > 2, x E R }
A (my keybord doesnt have the sign but its basicly an upside down "U") B
Plese help me!!
For set A, x is between -2 and 5, its mean that x can take all number bigger than -2 and smaller than 5, and you graph this on number lines
For set B we have B = {x l 6 - 2x > 2, x E R }
6-2x>2
6-2x-6>2-6
-2x+6-6>2-6
-2x+0>-4
-2x>-4
-2x : -2 > -4 : -2
x<2
