Answer 2

well..let's do the first first, alright?

Answer 3

first one*

Answer 4

okay please explain how to get answer i have no idea where to start on any of them ")

Answer 5

\[ x- 3 > -9\]
do you know how to do it when its \((x-3) = -9\)

Answer 6

well i would make the x into -3

Answer 7

Answer 8

Answer 10

okay i read it

Answer 11

if you have any problems then ask me..

Answer 12

okay for the first one what do we do??

Answer 13

\[x-3 >-9\]
we are solving for \(x\) why not you try it first?

Answer 14

okay-3 is the answer because -3 times -3 is 9 and 9 is greater than -9 right

Answer 15

@Mimi_x3

Answer 16

what? \(x\) is variabe..not times..

Answer 17

a variable*

Answer 18

i thought were suppose to replace x with number??

Answer 19

looks like you have to solve for \(x\) not substituting..

Answer 20

ohhh k so we add 3 to both sides right?

Answer 21

@SchoolFreak , mini isn't already helping you!

Answer 22

is*

Answer 23

i know

Answer 24

@Mimi_x3 so then if we add 3 both sides we have x > -6

Answer 25

Yes!

Answer 26

thats the answer?

Answer 27

yeah lol

Answer 28

you are basically solving for \(x\) thats all

Answer 29

oh haha x is greater than -6 , the graph would have open circle on -6 shading to the right is that right to?

Answer 30

correct

Answer 31

okay lets try the next one

Answer 32

–2x + 1 ≤ –11

Answer 33

why dont you try and tell me what you get

Answer 34

okay i think the first step is to add 2 to both sides?

Answer 35

think first; why add to 2? since its +1?

Answer 36

just isolate the -2x in the first hand so you wont get confused

Answer 37

okay so then you add 1 to both sides?

Answer 38

@Mimi_x3 would substract 1 from both sides right?

Answer 39

yes you subtract because it was a positive in the rhs

Answer 40

–2x + 1 ≤ –11 Okay so now we have -2x ≤ 12

Answer 41

not quite.. whats -11 - 1?

Answer 42

ohhh -12

Answer 43

yes, now you know what to do next

Answer 44

-2x ≤ -12

now we divide both sides by -2 and we have x ≥ 6

Answer 45

yes!

Answer 46

woo hooo also x is greater than or equal to 6 the graph would have a closed circle on 6 shading to the right

Answer 47

yes

Answer 48

okay let me try this next one all by myself

Answer 49

10 < –3x + 1

Answer 50

alright, if you need help ask me :)

Answer 51

kk

Answer 52

-9 > x @Mimi_x3 is that the answer??

Answer 53

nope..show me what you did

Answer 54

10 < -3x + 1

9 < -3x

-9 > x

Answer 55

you made a small mistake
whats 9/-3?

Answer 56

3

Answer 57

nope 9/ - 3

Answer 58

like 9 divide by negative 3

Answer 59

-3 is the answer??

Answer 60

yes but dont forget the inequality signs

Answer 61

-3 > x Is that the answer @Mimi_x3

Answer 62

not quite..the sign is wrong

Answer 63

No because we divide by a negative so we flip the sign

Answer 64

10 < -3x + 1
9< -3x
-3x > 9

Answer 65

understand so far?

Answer 66

why did u turn the equation on the last part

Answer 67

i dont know how to explain..but for inequalities to have to change the sign when you swap the equation..

you dont need to turn it; i just turned to prevent confusion

Answer 68

you have to change*

Answer 69

oh i didnt know that

Answer 70

lets not turn the equation then
lets start from 9< -3x

Answer 71

okay then then we dived and we -3 > x

Answer 72

then you still have to change the x for it to be in the front so x> -3

Answer 73

i mean x<-3

Answer 74

ohh k

Answer 75

@Mimi_x3 2(x + 5) > 8x – 8 this is the next one it looks hard lol

Answer 76

not really..expand it

Answer 77

the first side first

Answer 78

if we do the first side we will have 2x + 10 right on the left side??

Answer 79

yeah.

i gotta go now. sorry.

Answer 80

noo :(

Answer 81

hopefully someone else can help you..if not i'll be back later :)

Answer 82
