Question

abs of -3x-2<4 two answers

Answer 1

\[\left| -3x-2 \right| < 4\]

Answer 2

im sorry its suppose to be a -3 and not -2

Answer 3

if you were to graph the equation -3x-2 = y and then graph y=4 you could then visualize the area of the graph that must pertain to answer

Answer 4

\left| -3x-3 \right| < 4

Answer 5

yes

Answer 6

\[\left| -3x-3 \right| < 4\]

Answer 7

OK, cool

Answer 8

yep can anyone help me

Answer 9

sorry, was just graphing

Answer 10

so basically you to find the value for x such that when you plug into the equation you will get values between -4 and 4, never equal to 4

Answer 11

let's solve for -3x-3 = 4

Answer 12

ok

Answer 13

because of the negative slope on the X variable, i.e. (-3). X will have a negative value because a negative multiplied by a negative yields a positive

Answer 14

so we want to isolate x, therefore, first add 3 to both sides --> \[-3x - 3 + 3 = 4 + 3\]

Answer 15

--> \[-3x = 7\]

Answer 16

can i stop you for one second ... its suppose to be like a and/or answer

Answer 17

what do you mean?

Answer 18

we are finding the bounds, the values that x can be such that the equation is equals 4 or -4

Answer 19

like x=4/3 or x>9/3 like that

Answer 20

so we if found that x = -7/3, we then find that with -3x-3=-4, that x =-1/3

Answer 21

so between the values \[(-7/3, -1/3)\]

Answer 22

is that suppose to be less then or equal to ...or... greaterthen or equal too

Answer 23

the equation |-3x-3| will be less than 4

Answer 24

ok

Answer 25

just check the concept, if x = -2/3, the equations is (-3)*(-2/3) - 3= 2-3 = -1 ... which is less than 4

Answer 26

so x < -1/3 and x > -7/3

Answer 27

the notation with the parentheses is another way to represent that expression above

Answer 28

\[x = (-7/3, -1/3)\] where the parentheses mean that x cannot equal either of those numbers, but it can equal any number between them

Answer 29

let me know if you need more clarification ;)

Answer 30

it was rong but i posted another problem

Answer 31

Oh, the answers were incorrect?

Answer 32

they need to be in the correct which on is les then the other

Answer 33

sorry, looks like I solved the last part incorrectly, should be 1/3

Answer 34

x > -7/3 and x < 1/3

Answer 35

so -7/3 < x < 1/3

Answer 36

yeah

Answer 37

sorry about that
