Question

I need help with an absolute value question!

Answer 1

@johnweldon1993 could you help me please!

Answer 2

Firstly, you want to isolate that absolute value

So we need to add 8 to both sides of this equation

Answer 3

\[\large 2|3x - 5| - 8 = 8\]
\[\large 2|3x - 5| = 16\]

Then we need to completely isolate it by dividing this whole equation by 2 (it will cancel the 2 out in front of the absolute value bars)

\[\large |3x - 5| = 8\]

Now we just split this into 2 equations

\(\large 3x - 5 = 8\) and \(\large 3x - 5 = -8\)

solve for 'x' in each of those

Answer 4

Perfect!

Except for the first one, they didn't want it THAT way

\[\large 3x = 13\]
\[\large x = \frac{13}{3}\]
\[\large x = 4\frac{1}{3}\]

Answer 5

So which graph do we have? ^_^

Answer 6

D?

Answer 7

well 4 1/3 isnt an option.. but the -1 is there

Answer 8

...look at em all again (especially graph B :P

Answer 9

oh oops, i totally didnt see that.. thank you!
do you think you could help me with one more? im just trying to figure out how to set it up

Answer 10

Lol knew you would get it :P

and yeah of course :)

Answer 11

\[T= \frac{ 3U }{ E } solve for U\]

Answer 12

Alright so

\[\large T = \frac{3U}{E}\]

We want to get U by itself...if we multiply both sides of this equation by E...

\[\large T \times E = \frac{3U}{\cancel{E}} \times \cancel{E}\]

we will have

\[\large TE = 3U\]

Can you solve it from there?

Answer 13

\[\frac{ TE }{ 3 } = U\]

Answer 14

Perfect! :)

Answer 15

yay thank you so much! :)

Answer 16

No problem hun :)
