What's the question?

If you're asking for the roots, they're about 0.312 and 22.3

If you're asking for the derivative, it's 1.15x - 26

Start with the statement of the problem: 9 is 15% of x, or 9/x = 15/100.

Multiply both sides by 100x:

9/x * 100x = 900 for the left side and 15/100 * 100x = 15x for the right side. This gives: 900 = 15x.

Divide both sides by 15:

900 / 15 = 60 for the left side and 15x / 15 = x for the right side. This gives: 60 = x. Hence the answer is 60.

Multiply both sides by 100x:

9/x * 100x = 900 for the left side and 15/100 * 100x = 15x for the right side. This gives: 900 = 15x.

Divide both sides by 15:

900 / 15 = 60 for the left side and 15x / 15 = x for the right side. This gives: 60 = x. Hence the answer is 60.

If you have Windows Xp, try right-clicking on your screen, click 'Propetries', then click the "Settings" Tab, then there will be a picture of two screens - one has a number 1 on it, and the other has number 2. Click on number 2 and raise the "color quality" from Lowest (8 bit) to Highest (32 bit). Also, take the "Screen resolution" up to about less than half way. Then click "Apply". You will get a prompt asking if you really want to do this, so just hit yes. Your screen should turn on immediately after that.

Ps. After you do this, hit "Identify". There should be a giant number 1 on your computer, and a giant number 2 on your tablet.

Most likely you are not. The manual is very conservative!!! I have a 14000 gallon pool and I run my intex salt system during the summer at 10 to 12 hrs pump and 8 to 10 hrs chlorination in between those 12 hrs and my pool stays very clear. But..... If you don't clean the unit and let it alarm for low flow, low salt or not run the unit log enough, you WILL HAVE GREEN WATER!!!

Hope this helps, If it does, please rate the tip!

Your problem is that of percentage increase.

To calculate that, this is what you do:

Initial amount (Initial amount * percentage) = Percentage increase.

Let us call the initial amount, x.

Then our parameters are:

Initial amount = x

Percentage = 15/100

Final amount = 117300

So,

x (x * 15/100) = 117300

x (15x/100) = 117300

(x/1) (15x/100) = 117300

(100x 15x)/100 = 117300

115x/100 = 117300

cross multiplying

115x * 1 = 117300 * 100

115x = 11730000

dividing both sides by 115

115x/115 = 11730000/115

x = 102000.

So the original amount was $ 102000.

Hope that was helpful?

Have a wonderful day.

-15x^4 / 3x = -5x³ for x 0.

You should be able to figure this out without having to resort to a calculator. Note the "for x 0"... the two functions are identical everywhere, except the -15x^4 / 3x version is undefined for x = 0 (3 times 0 is 0 and you cannot divide by 0). The function has a "hole" at this point. -5x³ does not suffer from this defect, for x=0 it simply evaluates to 0, so you have to mention this fact to make it proper.

This expression 5x^2+15x+3 is not an equation, therefore it can have any value depending on the value of x. You have to make it an equation before looking for the particular value of x that satisfy your equation **5x^2+15x+3 =0**

This calculator cannot solve equations because it does not have an equation solver.

[3(x-5)-4(-3x+2)]-[4(6-x)]

[(3x-15)-(12x+8)]-(24-4x)

(-9x-23)-(24-4x)

-13x-(-1)

this is 9th grade stuff.
