The books answer says {xlx <5} or (- infinity, 5)
2007-09-03 04:05:57 · update #1
f(x) > g(x)
3x+2 > 5x-8
2 + 8 > 5x - 3x
10 > 2x
5 > x
x < 5
that's my answer...

3x + 2 > 5x - 8
10 > 2x
2x < 10
x < 5
try 4 3x4 + 2 = 14 5x4-8 =12

Set it up as an inequality.
3x+2>5x-8
subtract 3x from both sides
2>2x-8
add 8 to both sides
10>2x
divide both sides by 2
5>x
