Question

Can someone help me with linear inequalities please!

-2/3y>4

Answer 1

Ok

Answer 2

To get y, multiply by the reciprocal.

Answer 3

(-2/3)(-3/2)y= 4(-3/2)

Answer 4

When you multiply or divide by a negative number in an inequality, you must flip the sign. y<-6

Answer 5

Ok, thank you!! Would it be a problem if you can help me with 2 more problems please.

Answer 6

Ok

Answer 7

Ok, the first is \[\frac{ 1 }{ 5 }y-\frac{ 1 }{ 3 } \le \frac{ 2 }{ 3 }\] and the second one is \[\frac{ 2 }{ 3 }x-5 \le 7\]

Answer 8

1st one

You want y by itself so move the -1/3 to the other side.

Answer 9

Do u know how to do that?

Answer 10

After u do that you should have 1/5y less than or equal to 1

Answer 11

Yea, thats what I got. Is that my final answer, because on te back of my book it said the answer would be \[y \le -5\]

Answer 12

Almost. It's 5 where'd u get the neg

Answer 13

oh it's because 1/5y is actual -1/5y, Sorry. lol

Answer 14

Oh. Ok

Answer 15

Do u know what to do on the next one

Answer 16

Would be the same one as the first one?

Answer 17

Sort of give it a shot

Answer 18

The equation is this right 2/3x−5≤7, so I would add 5 to both sides, and that would get \[\frac{ 2 }{ 3 }x \le 7\], right?

Answer 19

Yes

Answer 20

not 7 but 12.

Answer 21

12

Answer 22

Then I would divide both side by 2/3, correct?

Answer 23

Or multiply by the reciprocal 3/2

Answer 24

ok, thank you! You were a big help =)

Answer 25

You're welcome
