Answer 2

@robtobey

Answer 3

do you know how to simply the equation you have up there

Answer 4

no :( @amiliver

Answer 5

@haleycoulter
just first subtract 1 from every side:)

Answer 6

yup then divide by 3 from both sides

Answer 7

so 15<3x<4 ? @Aperogalics

Answer 8

wait no 15<3x<3

Answer 9

yup:)
now divide by 3 every where:)

Answer 10

5<x<1 ? @Aperogalics

Answer 11

yup:)
Now this is ur part one's last stage seprete them and make it to interpret:)

Answer 12

and how do you do that? @Aperogalics

Answer 13

5<x<1
it has 2 inequality so first take 5<x or x<1 whatever u want so ur choice. what u want to take?????????

Answer 14

5<x

Answer 15

so it means x is a no. geater than 5.
now what about the second one??????

Answer 16

x is less than 1?

Answer 17

ya now tell me is there any no. possible which is less than 1 but greater than 5????????

Answer 18

no there isn't so there's no solution?

Answer 19

so done thats ur answer of first part now if there is no solution so can u draw its graph.....no
done:)

Answer 20

16 < 3x + 1 < 4
16-1<3x<4-1
15<3x<3
15/3<x<3/3
1<x<5

Answer 21

15/3<x<3/3
1<x<5 isn't it 5<x<1 @wwe123 :)

Answer 22

so fo this one ( -4x - 5 > -9 ) after it's been solved you'd get the graph of x > 1; open circle on 1, shading to the right

Answer 23

@Aperogalics

Answer 24

sry @haleycoulter one of the important point u must remember for inequality that sign changes when u multiply by a negative no. or take reciprocal of it. So sign changes here and it comes x<1 :)

Answer 25

oh yeah! thanks so much!
