This bit of your problem makes no sense!!. Because it is so small, that it is practically zero. So, you have no problem to solve!!.

Thank you!! It's wonderful to see you too! :)

That makes perfect sense, I forgot I had to factor first

Also next time I'll make sure to present it correctly

Thank you so much!

Hi Saseflower,

It is WONDERFUL to see you!!

(x2 + 9x +14) • 9/3x + 21 (9 over 3x + 21, the whole thing)

I think the meaning of your question is clear but this is ideally how it could hve been presented.

(x^2+9x+14) * 9/(3x+21)

\((x^2+9x+14) * \frac{9}{3x+21}\\ =(x+2)(x+7) * \frac{9}{3(x+7)}\\ \mbox{ (x+7) cancels out because one is on the top and one is on the bottom.}\\ =(x+2) * \frac{9}{3}\\ =(x+2) * \frac{\not{9}^3}{\not{3}^1}\\ =(x+2) * 3\\ =3(x+2)\\ =3x+6 \)

I have not explained the initial factoring that I did in the first line.  It is probably the hardest bit to understand.

Do you need me to explain more??  Which bits give you trouble.

Wow, your using a calculator app and your asking for an equation! :'D :'D :'D :'D Man you crack me up!

The Consumer Price Index is reported monthly by the U.S. Bureau of Labor Statistics. It reports the change in prices for a market basket of goods from one period to another. The index for 2000 was 172.2. By 2012, it increased to 229.6. What was the geometric mean annual increase for the period?

Consumer Price Index went up:229.6/172.2=1.333..........etc. in 12 years. So, the average or "mean" annual increase is: 1.3333^1/12=1.0242=2.42% per year.

Function notation is the way a function is written. It is meant to be a precise way of giving information about the function without a rather lengthy written explanation. The most popular function notation is f (x) which is read "f of x".

In my algebra class, when we learned it, my teacher just told us to think of it as another way to write y, because we used f of x in tables instead of y. Hopefully this helps!

A question like this would be perfect for the calculator found on this site! :) Just click home, and enter in those numbers, and it will give you your answer.

14 + 3a = 3 - 4(5a + 3)

Simplify

14 + 3a = 3 - 20a - 12

Subtract 3a from both sides

14 = 3 - 23a - 12

Simplify

14 = -9 - 23a

Add 9 on both sides

23 = -23a

Subtract -23 on both sides

-1 = a

And there you go :)

A(t) = 10.86-0.15x

HEY KID, WATCH YOUR LANGUAGE ON THIS SITE. IF YOU SWEAR, DON'T COME HERE.

1k+5+4-6k   =

1k - 6k + 5 + 4  =

-5k + 9

I think you just left out "k" in your original answer......

1k+5+4-6k : 1k-6k=-5k, 5+4=9, so you have: -5k + 9, or better: 9 - 5k, which is the correct answer.

I generated the regression line with this app......http://www.alcula.com/calculators/statistics/linear-regression/

(a)  y=1.09x-0.77  ......   or in our case..... C(t) = 1.09t - 0.77

(b) For 1993, we have

y = 1.09 (93) -0.77  = about 100.6 colors or 101 colors [ rounded]

thank u soooo muchhh

Hey....it ALL  looks good except for this one :

16)1k+5+4-6k

answer:-5+9

Try it again........

Good job  !!!!!

10)-5b-9+7

answer:-5b--2

11)x-8-1

answer:x-9

12)5m-1+6m+5

answer:11m=4

13)4-8k+k-7

answer:-7k-3

14)1+5x+x

answer:1+6x

15)1x+9+1+7x

answer:8x+10

16)1k+5+4-6k

answer:-5+9

17)2+6n+5n+7

11n+9

18)7v-1+10v-9

answer:17v--10

19)1+8x-4x+7

answer:4x+8

20)9x+7-4x+4

answer:5x+11

This can be factored as (x - 9)(x - 11) = 0 so the solutions are x = 9 and x = 11

Mmmmm......I don't know........

OK.....post the problems with your answers and we'll check them......we like people who have given good effort.....!!!!!

i have it all done but i just wanna check if i am right

Just post your questions, shellbie......we'll see what we can do......

-3-(-18)=-3+18=15

i will not do your homework but i well help you through your homework
