Question

Could someone please check this? Please? I really need this, its due tonight

Answer 1

it looks ok so your good it think

Answer 2

might want ot double chekc number 3

Answer 3

and number 4

Answer 4

absolute values can be broken up into 2 equations
\[|x| = n\]

is the equivalent of
\[x=n \]
and
\[-(x)= n\]

Answer 5

Okay checking now

Answer 6

So for #3 I should put this as the answer?
Y = 3
Y = -3
?

Answer 7

Same thing for #4?
S <= 3
S <= -3
?

Answer 8

\[\frac{|3s-4|}{2} \le 2.5\]

\[{|3s-4|} \le 5\]
2 inequalities
\[3s-4 \le 5\]
and
\[-(3s-4)\le 5\]

solve for both

Answer 9

First one is
s <= 3
and the second one
s => -1/3
Is that correct?

Answer 10

by the looks of it

Answer 11

AWesome c: Was #3 right?

Answer 12

@completeidiot

Answer 13

nope

try substituting -3 into the equation

Answer 14

My revised answer was wrong or the original?

Answer 15

there's a revised answer?

Answer 16

Yes I said
Y = 3
Y = -3

Answer 17

like i said, try plugging both those solutions in and see if it makes the equation true

Answer 18

i will say this,

10 is definitely not equal to 12

Answer 19

Well its not 3 and its not 2, is it a fraction?

Answer 20

wait is it 4 and -4?

Answer 21

SIGHHH
stop guessing and just solve it...

Answer 22

I'm trying to solve it but nothing is working

Answer 23

5+ |2y+1|=12

subtract 5 from both sides

|2y+1| = 7

now break up the absolute value into 2 equations

2y+1 = 7
&
-(2y+1)=7

now solve for both y

Answer 24

2y + 1 = 7
-1 -1
2y = 6
divide 2 divide 2
y = 3

-(2y + 1) = 7
-2y - 1 = 7
+ 1 +1
-2y = 8
divide by -2 divide by -2

y = -4

So the answer is y = 3 and y = -4?

Answer 25

@completeidiot

Answer 26

yes

Answer 27

AWesome c: You said everything else is correct?
