Question

Solve for x: |2x + 6| − 4 = 20
can someone please help??
@dan815 @bakonloverk @mathstudent55 @ObeySoph▲ @PRAETORIAN.10
someone??? please???

Answer 1

x = 9 and x = 11

x = −9 and x = 15

x = 9 and x = −15

No solution


these are the answer choices

Answer 4

\[\Large\rm |2x + 6| − 4 = 20\]Add 4 to each side,\[\Large\rm |2x + 6|= 24\]When you see absolute bars, you can drop them by tossing a plus/minus sign into the mix.\[\Large\rm 2x + 6= \pm24\]

Answer 5

So you now have two equations.
One with a positive 24,\[\Large\rm 2x + 6= 24\]And another with a negative 24,\[\Large\rm 2x + 6= -24\]

Answer 6

Do you understand how to solve for x in each case?

Answer 7

yes I do. I first subtract six from -24 which is -30 and divide it by 2 which is -15. and the one with the positive I divide 6 from positive 24 which is 18 and divide it by 2 which is 9

Answer 8

so is it -15 and 9??

Answer 9

Yay good job \c:/

Answer 10

can you help me with another one? I will definitely give you a medal afterwards

Answer 11

lol sure c:

Answer 12

Holding that medal hostage huh? >.< I see how it is lol

Answer 13

yeah lol

Answer 14

The minimum and maximum temperature on a cold day in Lollypop Town can be modeled by the equation below:

2|x − 6| + 14 = 38

What are the minimum and maximum temperatures for this day?

x = −9, x = 21

x = −6, x = 18

x = 6, x = −18

no solution

Answer 15

Same as the last one ya dingus!
I would recommend isolating the absolute stuff before dropping the bars.

Answer 16

I took this test already 10 times but I always only get 3/10 right

Answer 17

ok well thank you

Answer 18

for the answers I get 11 and -27??????

Answer 19

\[\Large\rm 2|x − 6|+14=38\]Subtract 14 from each side,\[\Large\rm 2|x − 6|=24\]Divide by 2,\[\Large\rm |x − 6|=12\]Drop the jail bars,\[\Large\rm x-6=\pm12\]Hmm no those don't seem to be the answers we're looking for.

Answer 20

18 and -6??

Answer 21

yay good job \c:/

Answer 22

Getting confused by some of those algebra steps maybe?

Answer 23

weird. I still only got 5/10. but thank u so much. the ones u helped with I got right tho c:

Answer 24

aw :c
is it FLVS where you have to get at least 8 or something?

Answer 25

yea it really sucks.
