Thanks Heuraka, I am going to take a different path.  

y= 3x+3

The y intercept is where x=0    so 3x=0    put your finger over 3x you don't need that bit!

y=3

-----------------

The x intercept is where y=0  so you have to solve

0=3x+3

-3=3x

x=-1

-----------------------

Now you have your 2 intercepts it is really easy to graph.   

Alan you are just trying to make things difficult.   LOL 

But yes I have to give you that one.    

There are an infinite number of possibilities for this sequence as can be seen from the table below (though I guess the simplest one is the one suggested by Melody)!

Or it could be an oscillating sequence: 1/7 0 -1/7 0 1/7 0 -1/7 0 1/7 0 ...etc.

Or ...!!!

$$w=\frac{-1}{-1/2cos(theta)^2+(7/16)}$$

firstly, do you mean

 $$\\(cos\theta)^2\;\;or\;\;cos(\theta^2)\\\\
note:\;\;cos^2\theta \;\;means\;\; (cos\theta)^2$$

Can you simplfy the following please.
$$w=\frac{-1}{-1/2cos(theta)^2+(7/16)}$$

Well I stand corrected.  Thanks Alan.  

Dragon might still be 18 hours behind me I guess it depends on whether he ahs got daylight savings too!

If he has daylight savings then the will only be 17 hours behind me I guess otherwise he is still 18 hours behind.  

After a quick search it appears that Los Angeles does have daylight savings so Dragon you are probably 17 hours behind me.

What is it that you want to be done with this?

Actually Melody, you are currently only 9 hours ahead of the UK as we have a 1 hour daylight saving time (or British Summer Time as it's known here) during the (northern hemisphere) summer months.

Multiply the 2.5 cm/year by 75*10⁶ years to get the result in cm.  Then divide the result by 10⁵ cm/km to get the result in km.

I can't see the images either.

For each music player divide the number of dollars by the number of gigabytes and see which result is smaller. 

Neither.  If x² = -1 then x = ±i , where i is the square root of minus 1.

$$\frac{(u^3\times u^6)^4}{8u^2}=\frac{(u^9)^4}{8u^2}=\frac{u^{36}}{8u^2}=\frac{u^{34}}{8}$$

Yes.  Type in factor(N), where N is your number and press enter. e.g.

$${factor}{\left({\mathtt{50}}\right)} = {\mathtt{2}}{\mathtt{\,\times\,}}{{\mathtt{5}}}^{{\mathtt{2}}}$$ 

125^2/3 = 5² = 25

25^1/2 = 5

So: 125^2/3/25^1/2 = 25/5 = 5

(2x - 3)*(x + 5) = 2x² +7x -15

Thaank you!!!!

Just divide all those numbers by 14

All you are doing is taking away 1/7 each time.

You can think of negative numbers as cold numbers.

If you take away cold from a room then the room gets warmer.

so       - - = +

$$\frac{5}{18}+\frac{3}{8}$$

Now you can either do it on a calculator or get a common denominator and (8*18/2) and add them that way. 

On this calcualtor it is 

atan(12/5) 

The calc is on the home page.

You live in Pacific Time Zone   

Find the value of y so that the points (-5,10) and (3,y) lie on a line with slope -3/8

$$slope = \frac{\Delta y}{\Delta x} = \frac
{y-10}
{3-(-5)}
=
\frac
{y-10}
{8}
\\\\
\text{also slope } = -\frac{3}{8}$$

$$so\ we\ have \quad
\frac{y-10}{8} =
-\frac{3}{8} \qquad or\ \quad y-10=-3$$

the value of y = 7
