9+10=19   always did and always will

People just think it is funny to tell you stupid things. 

They think it is  even funnier when they can see your confusion.

It is kind of funny I guess, I am smiling as I write this post.  :D

Im supposed to write the equation that describes each line in slope-intercept form.the question is "The line that passes through (1,5) and (4,-4). now i know y=mx+b

and i found what m is (slope=-3 or -3/1). so i need to find what b is. pls help...?

I have absolutely no idea why you sent CPhill to that link.......

You have already done half the work here

y= mx+b                   m=-3

so

y=-3x+b          

Now id you put ANY point that is on the line into this equation you will get the value of  'b'.

I am going to use (1,5) but if I used (4,-4) I would get exactly the same answer.

y=-3x+b         x=1,  y=5

5=-3*1+b

5=-3 +b

8=b

so

y= -3x + 8   is the equation of the line :)

CPhill did it a different way.  There are lots of ways you can do these.  :D

2 since both 8 and 18 are even and you can't put 4 into 18 evenly

Could you please talk to us in English Ape4 ?

You see we are "mature" and it takes to much effort to work out text speak.  LOL

(LOL is one of the few that I have worked out and adopted )

no you aren't stupid. I'm not sure what's going on with those numbers though. I've seen them before I don't understand how 9+10=21 though 

oh, okay!

Great!!

Thanks for your help :)

And thank you too, Guest!!

Oh. Was I suppose to put it as a fraction, instead of a decimal?? :)

I should really have written the final answer as a mixed numeral or an exact decimal

It doesn't really matter so long as your answer is exact - your answer was not exact!

My answer  was  -23/15

the best answers would be

\(-1\frac{8}{15}\qquad or \qquad -1.5\dot3\)

Oh. Was I suppose to put it as a fraction, instead of a decimel?? :)

15x+36=13

      -36   -36

15x     =  -23                            [you seemed to have left this bit out :/ ]

divide both sides by 15 and you get

x= -23/15

with a unit rate of 4.25/10.20 how much would that be with 6 instead of 4.25

your question is a bit vague.

Do you mean something like this

I get 4.25 yards for $10.20    Hoe much for 6 yards?

that would be

4.25/10.2*6    dollars

Tau is the sixteenth Greek letter, which is used as a symbol in Math, Physics, Chemistry, Astronomy....etc. In Math, it is generally used to mean "2Pi".

3(10x+12)=15x+3

30x+36=15x+13

-15x      -15x

15x+36=13

      -36   -36

Then i divided, which got mee...

X=-1.5

Yes you CAN do maths Miss Hayley !!

You just have to practice a lot.

3(10x+12)=15x+13

My answer i got was..

X=-1.5

This is how oyu check your answer.

LHS = 3(10*-1.5+12) = 3( -15+12) = 3*-3 = -9

RHS= 15*-1.5+13 = -22.5+13 = -9.5

No they are not the same.  So one of us did someting wrong :(

Show us your working so we can explain what you are doing wrong :)

NOTE: you can also check your answers to equations like this using the web2 calc.

Just put your equation into the input line and press =.

BUT you do need to know how to check it by hand as well, and you will not remember if you do not practice it a lot of times :)

yep. heres some tips:

1. dont bite a bone(there cartlige, makes a horrible noise in ur mouth)

2. Cook it THOUROUGHLY. undercooked babies can make you ill

3. REMOVE THE BABIES BLADDER AND INTESTINES. they taste horrible, kinda like pee and c**p.

4. Dont drink the Stomach Acid.

Have Fun!(lulz)

Omggg. :(

I cant do math!

Solve for x:
3 (10 x+12) = 15 x+13

3 (10 x+12) = 3 (10 x)+3 12:
3 10 x+3 12 = 15 x+13

3×12  =  36:
3 10 x+36 = 15 x+13

3×10  =  30:
30 x+36 = 15 x+13

Subtract 15 x+13 from both sides of 30 x+36 = 15 x+13:
30 x-15 x+13+36 = (15 x+13)-15 x+13

(15 x+13)-(15 x+13) = 0:
30 x-(15 x+13)+36 = 0

-(15 x+13) = -13-15 x:
30 x+-13-15 x+36 = 0

Grouping like terms, 30 x-15 x-13+36 = (30 x-15 x)+(36-13):
(30 x-15 x)+(36-13) = 0

30 x-15 x = 15 x:
15 x+(36-13) = 0

36-13 = 23:  15 x+23 = 0
Answer: |  - 23/15

Simplify the following:
(k-1)^2+2 k-1+k+1

Grouping like terms, (k-1)^2+2 k-1+k+1 = (2 k+k)+(k-1)^2+(1-1):
(2 k+k)+(k-1)^2+(1-1)

2 k+k = 3 k:
3 k+(k-1)^2+(1-1)

1-1 = 0:
3 k+(k-1)^2

(k-1) (k-1) = (k) (k) + (k) (-1) + (-1) (k) + (-1) (-1) = k^2-k-k+1 = k^2-2 k+1:
k^2-2 k+1+3 k

Grouping like terms, k^2+3 k-2 k+1 = k^2+(3 k-2 k)+1:
k^2+(3 k-2 k)+1

3 k-2 k = k:
Answer: |  k^2+k+1
 

who... who buys SNAKES at SCHOOL! and WHY on EARTH are you SPENDING MONEY at SCHOOL TOO! im confus. srsly.

You eat babies?

-R

6.3/0.7 = 9

Also, please try to keep it clean there are kids on this website.

For 8 days, Gerry spends 1.25 per day........and for 2 more days, she spends 1.25 + .55 = 1.80

So

8(1.25) + 2(1.80)  = $13.60

$7.35 if she buys a snake both weeks, $6.80 if she does not.

k no cloo wut u just did but if i get this question wrong, u have to subscribe to meh on youtube. (link is https://www.youtube.com/channel/UC2V77M0HoKjlISZmYMrZeFQ )
