I honestly can't read the first two :( Do you think you can try to draw it using the draw tool?

\[\frac{y}{2} <-3\] I will give you en example for this one: If you have \[\frac{a}{5}<-2\] => \[5 \cdot \frac{a}{5} <-2 \cdot 5\] \[a<-10\] See you can see what is going on in this example.... Hint multiple 2 on both sides for that problem..

so what did you get for the first one?
anonymous
  • anonymous
no clue om stilll trying to figure it out
anonymous
  • anonymous
i got y is less than -1
myininaya
  • myininaya
So did you multiply 2 on both sides?
myininaya
  • myininaya
2(-3) is not -1
anonymous
  • anonymous
-6
myininaya
  • myininaya
y<-6 is the solution set
anonymous
  • anonymous
the second one im kinda stuck
anonymous
  • anonymous
d is greater than or equal to 9.5
myininaya
  • myininaya
\[-1.5d \ge 9\] How do you get d by itself?
anonymous
  • anonymous
add 1.5 to both sides
myininaya
  • myininaya
No to undo multiplication by -1.5 you divide by -1.5 But when you multiply or divide by a negative on both sides this flips the inequality sign
anonymous
  • anonymous
-6
myininaya
  • myininaya
yes now what about the inequality part?
anonymous
  • anonymous
N is less then or equal to -6
anonymous
  • anonymous
3rd one. i dont get at alll
myininaya
  • myininaya
ok d not N but yes that is right
anonymous
  • anonymous
Thanks your helping soo much! the third one i dont get at all i need help step by step

5s – 3 + 1 < 8 Combine like terms first -3+1=?
anonymous
  • anonymous
-2
anonymous
  • anonymous
is it 3<10
anonymous
  • anonymous
s<10
myininaya
  • myininaya
So we have 5s-2<8 right?
anonymous
  • anonymous
yes. so wouldnt you +2 to 8
myininaya
  • myininaya
yes! :) 5s<10 Divide both sides by 5 and you win! :)
anonymous
  • anonymous
thankkk you! and now the last one
myininaya
  • myininaya
8d + 2 < 5d – 7
myininaya
  • myininaya
So what do you think one possible first step is?
anonymous
  • anonymous
Subtract 2 from both sides
myininaya
  • myininaya
ok! :) 8d<5d-9 That gives us this! VEry good!
myininaya
  • myininaya
Now?
anonymous
  • anonymous
not sure this is were i got stuck when i tryed doing it before:(
myininaya
  • myininaya
What did you try before?
anonymous
  • anonymous
adding 9 to both sides
myininaya
  • myininaya
Get your terms that have the same variable part together how do you get the 5d part on the other side?
myininaya
  • myininaya
What happens if you subtract 5d on both sides? Try that/
anonymous
  • anonymous
you get 2d
myininaya
  • myininaya
nope nope
anonymous
  • anonymous
0
myininaya
  • myininaya
8-5=3 right? So 8d-5d=3d
myininaya
  • myininaya
So we have 3d<-9
