Question

olve for x: −5|x + 1| = 10

x = 0

x = −3 and x = 1

x = −1 and x = 3

No solution

Answer 1

simple..... just do this....
−5(x + 1) = 10 and −5(x + 1) = -10... now solve....

Answer 2

when you divide by -5 on both sides ,what do u get ?

Answer 3

remember :
|....| can never be negative!

Answer 4

-5x-5=10
=-3

Answer 5

so 3

Answer 6

no...
first step is to divide both sides by -5
in −5|x + 1| = 10

what do u get ?

Answer 7

no just divide by -5 on both sides
those arent parentheses it is the absolute value symbol
paki got u confused...

Answer 8

i have no clue

Answer 9

what is 10/-5???

Answer 10

-2

Answer 11

yes,
so u get

|x+1| = -2
right ?

Answer 12

ya

Answer 13

is that even possible ?

Answer 14

no

Answer 15

remember : answer to absolute value sign can never be negative

Answer 16

so whats your conclusion ?

Answer 17

so its 2

Answer 18

no, its not 2
since |x+1| can never = -2
there is no value of 'x' !

Answer 19

so its no solution

Answer 20

yessss :)

Answer 21

thank you

Answer 22

can you help me with one more please

Answer 23

welcome ^_^

sure!

Answer 24

thank you :)))

Answer 25

-3|x + 7| = -12

x = 5 over 3, x = −19 over 3

x = −3, x = −11

x = −3, x = 11

No solution

Answer 26

divide both sides by -3

Answer 27

always first try to isolate the absolute value sign

Answer 28

4

Answer 29

im really connfused with absolute values

Answer 30

now 4 is positive so go on to the next step,
x+7=4 and x+4=-7
now solve for x

Answer 31

-3 and -3

Answer 32

general rule!

when |a| = b
we have a= b or a = -b

Answer 33

no..
x+7=4
subtract 7 on both sides

x+7=-4
subtract 7 on both sides

Answer 34

nvm its -3 and -11

Answer 35

good job

Answer 36

thank you

Answer 37

and i have one more

Answer 38

Solve for x: |2x + 6| − 4 = 20

x = 9 and x = 11

x = −9 and x = 15

x = 9 and x = −15

No solution

Answer 39

add 4 on both sides...

Answer 40

24

Answer 41

wait no

Answer 42

9

Answer 43

|2x+6| = 24
now use the general rule which i gave you!

Answer 44

when |a| = b
we have a= b or a = -b

when
|2x+6|= 24
....?....

Answer 45

9

Answer 46

is it no solution

Answer 47

it has to be one of these
x = 9 and x = −15
x = 9 and x = 11
No solution

Answer 48

9 is one of the solution, whats another ?

Answer 49

2x+6 = 24 gave you x = 9

2x+6 = -24
gives you what ?

Answer 50

-15

Answer 51

so its 9 and -15

Answer 52

yes! correct :)

Answer 53

Solve for x: |x + 2| + 16 = 14

x = −32 and x = −4

x = −4 and x = 0

x = 0 and x = 28

No solution

Answer 54

is the answer to this one -32 and -4?

Answer 55

this is easy
subtract 16 from both sides
what do u get ?

Answer 56

and no, thats not the answer

Answer 57

-2

Answer 58

i think its no solution

Answer 59

can |x+2| ever be -2 ??

Answer 60

no

Answer 61

correct, so its no solution :)

Answer 62

The minimum and maximum temperature for a day in Cupcake Town can be modeled by the equation below:

3|x − 8| + 15 = 18

What are the minimum and maximum temperatures for this day?

x = 1, x = 17

x = −7, x = 9

x = 7 x = 9

No solution

Answer 63

is this one x=7 x=9

Answer 64

ask new question in a new post :)
so that others can help you too!
bdw, you are correct for this :)

Answer 65

ok thanks

Answer 66

welcome ^_^
