Question

What is the solution set for |–2x + 8| = 12
Answer
x = 2 and x = 10
x = –2 and x = 10
x = –2 and x = –10
x = 2 and x = –10

Answer 1

what do you get when you plug in the options?

Answer 2

its the first one right?

Answer 3

i dont think it would be, but we can do better than just guess

Answer 4

hmm

Answer 5

what is -2 times 2?

Answer 6

-4

Answer 7

and -4 + 8 = ?

Answer 8

4

Answer 9

would you say that |4| = 12 then ?

Answer 10

no...

Answer 11

then x cannot equal 2

Answer 12

lets try 10 :)

Answer 13

what is -2 times 10?

Answer 14

-20

Answer 15

and -20 + 8 = ?

Answer 16

12

Answer 17

well, -12 yes; does |-12| = 12 ?

Answer 18

yes

Answer 19

x = –2 and x = 10

Answer 20

then we conclude that x does not equal 2; and it does equal 10

Answer 21

amistre can u stay here? im doing attest

Answer 22

A test and I'm gonna need some more help

Answer 23

hmmm ..... doing a test doesnt sound very ethical to me; I can help, but I want you to find the answers

Answer 24

I knwo I just need you to help me figure out how to solve the problems and there is only 10 more questions

Answer 25

lets do the next one then and see where it leads

Answer 26

What are the solution intervals for |x + 5| > 3?
Answer
x < –8 or x > –2
x > –8 or x < –2
x < 8 or x > –2
x > 8 or x < –2

Answer 27

lets start out by seeing of x=0 is good or bad

Answer 28

wouldnt it be good?

Answer 29

when x=0 we get: |5|>3 is this a true or false result?

Answer 30

true

Answer 31

it looks good to me; so we can narrow it down to between 2 numbers

Answer 32

\[\cancel{x < –8 or x > –2}\]
x > –8 or x < –2
x < 8 or x > –2
\[\cancel{x > 8 or x < –2}\]

Answer 33

lets try x = 7

Answer 34

it works

Answer 35

then this one looks to be the right area

x < 8 or x > –2

Answer 36

Ok sweet~
here is the next one



On the graph of the equation 3x – 2y = –18, what is the value of the y-intercept?
Answer
6
–9
9
–6

Answer 37

when x=0; what does y=?

Answer 38

0?

Answer 39

or 1?

Answer 40

i would say neither since 0 or 1 is not an option is it

Answer 41

ugh this is confusing

Answer 42

lets try it again:
when x = 0; y = ?

3x – 2y = –18
0
------------
0 -2y = -18

Answer 43

-9?

Answer 44

or actually its 9

Answer 45

close, but two negatives give a + result; id go 9 :)

Answer 46

so the answer is 9 right?

Answer 47

i would go with 9 yes

Answer 48

What is the slope of the line which passes through (–6, 0) and (4, 0)?
Answer
0
–2
undefined
2

Answer 49

dont you do like 0-0 and 4-(-6) or something liek that>

Answer 50

both your y values are the same; which means the no matter what you pick for x; you always have the same y value

Answer 51

like y2-y1 and x2-x1
