no im doing summer school and school starts in two weeks and i have about 70%of a class to do
jim_thompson5910
  • jim_thompson5910
so because absolute value is never negative, this means |x| is never negative
jim_thompson5910
  • jim_thompson5910
so is |x| > -9 always true? sometimes true? or never true?
anonymous
  • anonymous
somtimes true
jim_thompson5910
  • jim_thompson5910
why sometimes? |x| is never negative so it's either 0 or positive
anonymous
  • anonymous
so never true
jim_thompson5910
  • jim_thompson5910
so you're saying that if z is positive, then z > -9 is false?
anonymous
  • anonymous
always true
jim_thompson5910
  • jim_thompson5910
z > -9 is false? or true?
jim_thompson5910
  • jim_thompson5910
z is positive

  • anonymous
tru
jim_thompson5910
  • jim_thompson5910
so |x| > -9 is always true therefore, there are infinitely many solutions
anonymous
  • anonymous
ok
anonymous
  • anonymous
so all reals or does reals constitute -+ but no fractions??
jim_thompson5910
  • jim_thompson5910
what do you mean?
anonymous
  • anonymous
nvm so its a
jim_thompson5910
  • jim_thompson5910
no I already told you the answer
jim_thompson5910
  • jim_thompson5910
infinitely many solutions means what?
anonymous
  • anonymous
all reals
jim_thompson5910
  • jim_thompson5910
