Question

Please help!!!!
Which graph represents the solutions to the inequality |4x - 8| > 8

Answer 1

@amistre64 @thomaster @undeadknight26 @ParthKohli @SolomonZelman @ganeshie8 @Hero @Luigi0210 @Loser66 @triciaal

Answer 2

the one that cuts |4x-8| off at y=8

Answer 3

those are the answer choices

Answer 4

@amistre64 I don't understand

Answer 5

oh, well it looks like you narrowed it down some, can you tell me why you want to pick B?

Answer 6

well its not going to be a closed circle right because its greater than and not greater than or equal to

Answer 7

good, what else do we know .... that will help us out?

we know that 0<8 so try to solve 4x-8 = 0 to see what NOT to include

Answer 8

x=2?

Answer 9

yes x=2 makes it 0, so we do NOT want the section that has 2 in it .... B fits the bill perfectly.

Answer 10

o thank you so much

Answer 11

well, there is no color legend, im assuming blue are solutions, and yellow are not?

Answer 12

otherwise its hard to tell if we pick A or B .... depends on what color defines the solution area.

Answer 13

yes the blue are the solutions

Answer 14

yay!! lol

Answer 15

first let
4x -8 = 0
x=2
when x = 0 y = -8 but use the absolute value = 8
draw the line using points (08) and (2,0)
shade the section to the right ask for greater than 0

Answer 16

sorry i had 4x -8 >0 it shoud be>8 to give the point (4,0)
won't change the answer still B

Answer 17

thank you could you help me with another

Answer 18

post

Answer 19

that's the same one

Answer 20

no its a different one

Answer 21

now it is
2x -4 <=14

Answer 22

yes

Answer 23

use the same process

2x - 4 + 4 = 14 + 4
x = 9
boundary

Answer 24

when x = -9 y = 22

Answer 25

ok

Answer 26

C include the points shaded circle
when x = -5
solution -5 to x = 9 include

Answer 27

ok thank you

Answer 28

wait so which one would it be

Answer 29

sorry B reason correct

Answer 30

so very sorry i am getting confused
when we have absolute we are taking the positive value

Answer 31

last one was easy i drew the graph and then read the numbers

Answer 32

o ok thank you so much

Answer 33

let me do the graph to confirm give me a few minutes

Answer 34

-5 to 9 included

Answer 35

already showed when x = -9 value =22 so not included
limit is -5
