Yes, i just posted this right when i saw the answer on my other post XD. Truely apologize!

(A)33.2 is less then 33.04 FALSE                       (B)7.4 is less then7.388 FALSE

(C)5.0329 id less then 5.044 TRUE                   (D)0.5 is less then0.005 FALSE

Hayley...this has been answered in your other post....

y + 9  =  (x - 4)^2

You have the x coordinate correct

Put it in this form, Hayley

y  = (x - h)^2  +  k

So we have.......  [subtracting 9 from both sides]

y = (x - 4)^ - 9

In this form.....the vertex can be read thusly, as  ....      (4 , -9)

In other words......the x coordinate of the vertex is the x value that makes x - 4  = 0  [this is 4[......   and the y coordinate  is just the last term and its associated sign.......

Do you mind me asking how you got that answer? just so i know how to do it next time. please and thank you! and i have not graphed it yet :) i always siggn my name at the bottom, and this girl keeps going off on me >:(

Hayley.....  Actually, Melody has encouraged people to sign their names if they are posting as guests ... so no worries!

I get the vertex as   4 , -9     

  Did you try the graphing function of the calculator so you can look at it?

the answer is A

Melody: Do you think that I should take him/her for their word of phoning them and collecting the $500 reward for finding the value of x?????!!!!!!!!!. Just kidding!!.

(4, -9)

Let x be the number of $5 bills and y be the number of $10 bills

And x + y  = 25    (1)

And value of a five dollar bill * x  +  value of a ten dollar bill * y  = total amount   ......in other words.....

5x + 10y  = 230   (2)

Rearranging (1), we have that   y = 25 - x      and putting this into (2), we have

5x + 10(25 - x)  = 230    simplify

5x + 250 - 10x   = 230

-5x + 250  = 230       subtract 250 from both sides

-5x  = -20            divide both sides by -5

x = 4     this is the number of $5 bills she has

And  y = 25 - x   =    25 - 4   =   21     .....and this is the number of $10 bills she has

first of all, what do you think the answer is? :D

Okay.

K but ppl dont need to know ur name

Omggoshh. Please calm down. I just want some help in math.

K U may need to make a account or stop putting ur name cause im pretty sure ppl dont need to know ur name.

how to calculate on scientific calculator csc cot sec?

Learn and memorize the relationships between, Sin, Cos, Tan and Csc, Cec and Cot, as follows:

Sin=1/Csc: Cos=1/Sec: Tan=1/Cot.

O_o

???

m=movie v=video

Then 2m + 6v = 38     and   5m + 3v = 32

Solve FIRST equation for v  

6v=(38-2m)

v= (38-2m)/6     Substitue this into the SECOND equation and solve for 'm'

5m + 3 (38-2m)/6 =32

10m + 38 -2m = 64

8m= 26    or m= $ 3.25

Now sub into one of the two equations to find v

2(3.25) + 6v = 38

6v=31.5  or v = $ 5.25

Thanks!

Here you go, Hayley..........http://www.purplemath.com/modules/parabola.htm

This is pretty detailed, so take it slowly.......!!!!!!

A lot. ;)

This is the ratio of 3 to 4: 3/4

One month Milan rented 2 movies and 6 video games for a total of $38 . The next month he rented 5 movies and 3 video games for a total of $32 . Find the rental cost for each movie and each video game

Let m=price per movie

Let v=price per video

2m + 6v=38, and

5m + 3v=32

Solve the following system:
{2 m+6 v = 38 |     (equation 1)
5 m+3 v = 32 |     (equation 2)
Swap equation 1 with equation 2:
{5 m+3 v = 32 |     (equation 1)
2 m+6 v = 38 |     (equation 2)
Subtract 2/5 × (equation 1) from equation 2:
{5 m+3 v = 32 |     (equation 1)
0 m+(24 v)/5 = 126/5 |     (equation 2)
Multiply equation 2 by 5/6:
{5 m+3 v = 32 |     (equation 1)
0 m+4 v = 21 |     (equation 2)
Divide equation 2 by 4:
{5 m+3 v = 32 |     (equation 1)
0 m+v = 21/4 |     (equation 2)
Subtract 3 × (equation 2) from equation 1:
{5 m+0 v = 65/4 |     (equation 1)
0 m+v = 21/4 |     (equation 2)
Divide equation 1 by 5:
{m+0 v = 13/4 |     (equation 1)
0 m+v = 21/4 |     (equation 2)
Collect results:
Answer: | m=13/4=$3.25  and  v=21/4=$5.25
