Question

x-2>-5 or 5x>25

Answer 1

first solve x - 2 > -5

do this by adding 2 to both sides. what do you get?

Answer 2

-3 ?

Answer 3

right x > -3

Answer 4

now solve 5x > 25

Answer 5

btw the said was suppose to be " greater than equal to"

Answer 6

which one?

Answer 7

so i just wrote greater than

Answer 8

Doesn't matter.

Answer 9

Sorry for interrupting, but you have to solve these exactly like you solve \(\rm x - 2=-5\) and \(5x = 25\).

Answer 10

\[x - 2 \ge -5 \; \text{or} \; 5x \ge 25\]
??

Answer 11

Yes that correct except the first one is the the greater than symbol

Answer 12

oh so \[x - 2 > -5 ~\text{or} ~ 5x \ge 25\]

Answer 13

Yess

Answer 14

so anyway \[5x \ge 25\]
do you know how to solve for x?

Answer 15

x=5 ?

Answer 16

x \(\ge \) 5
the symbols matter

Answer 17

so since x - 2 > -5 is x > -3

and 5x \(\ge\) 25 is x\(\ge\) 5

your answer would be x > -3 or x\(\ge\) 5

Answer 18

@ParthKohli or is different from and

Answer 19

but when it comes to graphing x>-3 is not included

Answer 20

if you mean open circle..yes

Answer 21

yeah i mean open circle , greater than is always included

Answer 22

greater than is always included?

Answer 23

lol nvm i cant explain it here :P

Answer 24

i notice

Answer 25

Okay guys one more question

Answer 26

shoot

Answer 27

excluded....you have to draw a dotted line if it is greater than and you have to draw a dark complete line for greater than or equal to....

Answer 28

hahah thats exactly what i meant ^

Answer 29

sorry @lgbasallote if I interrupted you..you can carry on with your client..

Answer 30

l3xl +8>5

Answer 31

first of all, subtract 8 from both sides

Answer 32

yeah so its 5-8=-3

Answer 33

right

|3x| > -3

Answer 34

so absolute value of 3x=-3 ?

Answer 35

again. remember that signs matter. > is different from =

Answer 36

yeah sorry

Answer 37

you'll see the importance in the next step

Answer 38

since |3x| > -3 you turn this into two equations

3x > -3 and 3x < 3

now solve for x in each one

Answer 39

6 and 1 ?

Answer 40

hmm

first solve 3x > -3

divide both sides by 3

Answer 41

-1

Answer 42

x=-1 or x=1 ?

Answer 43

...signs...

Answer 44

it's not equal signs...

Answer 45

sign

Answer 46

nvm then

Answer 47

it should be x>-1 and x<1 signs are very important

Answer 48

Alright im done , thank you guys so much . you really helped me

Answer 49

@lgbasallote Try to think! If \(\rm x > 5\), it still satisfies \(\rm x\ge -3\)

Answer 50

in this case yes it is. but the fact remains that or is different from and
