and are you supposed to turn the greater than or equal to sign around?
anonymous
  • anonymous
when you multiply or divide by a negative number, yes
bruno102
  • bruno102
so would the answer be x is less than or equal to - 3/4?
anonymous
  • anonymous
by the way its -3/2
bruno102
  • bruno102
ohhh how do you get that though? I dont get how 6/-4 is that
anonymous
  • anonymous
6/-4 = 3/-2 you can check with calculator but it's (3/-2)*(2/2)
anonymous
  • anonymous
which is (3/-2)*1
bruno102
  • bruno102
so your basically just simplifying the 6/-4
anonymous
  • anonymous
yes. and final answer is x <= -3/2
