What does the 'm' represent?

You can use the calculator to get the decimal answer of 26 ÷ 4.

Divide the total cost by the total number of gallons:     $36.89  ÷  8.6  =        (the cost for one gallon of gas)

The x-intercept is the point (x, 0).

To find the x-intercept of an equation, substitute 0 in for y:

              -2x + 5y  =  -10

              -2x + 5(0)  =  -10

              -2x           =  -10

                          x  =  5

If you used the clockwise matrix times the matrix of points, the matrix solution would give you the new points:

|   cos90    sin90  |    X    |  1  3  1  -3  -2  |       =  |                             |                         

| -sin90    cos 90  |          |  3  2  -1  -2  2  |            |                            |

Where the first column in your answer matrix represents D', the second column represents E', etc.

What does the x-intercept represent?  It is the point (or points) where the graph crosses the x-axis.

What can it be used for?  It represents the answers to the associated equation. 

 For example, the line  y = 3x - 6 has its x-intercept at (2,0) And if you were asked to solve the equation        3x - 6 = 0, the answer would be x = 2.

-4x

Notice that the "divide and average" method is very simple.......the only problem with the method - and some others, as well - is that the numbers generated are difficult to work with........unless you have a calculator......!!!!

ok whats 8 times 3 then minus three

Before the creation of hand-held calculators, an algorithm was taught in algebra classes; it can be found at 

its 7 and 1/5 in fraction and 7 and a half  in non fraction 

24/27  =  8/9  ≈  0.889

(m/s)  ÷  (m/s²)  =  (m/s) x (s²/m)  =  s 

Answer:  (8/9)s  or  0.889 s

Yes, one approach is to use a divide and average approach.

Example: $$\sqrt{3}$$

Guess an approximate answer, say 2. 

• Divide to obtain 3/2 = 1.5 and average to obtain (2 + 1.5)/2 = 1.75.
• Divide to obtain 3/1.75 = 1.71428 and average to obtain (1.75 +  1.71428)/2 = 1.73214
• Divide to obtain 3/1.73214 = 1.73196 and average to obtain (1.73214 + 1.73196)/2 = 1.73205

This is already close to the value provided by a calculator and becomes even more accurate if you use more decimal places and repeat the divide and average a few more times.  This method was known for thousands of years.

it dependson the number of miley cyrcus he had to begin with and the number of house he had to begin with if he had 5 houses and 2 miley crycus then zero for each ok then 

i dont know i belive it would be very hard to do that though it would take a math wiz

Take the log of both sides.....so we have

log x^0.4 = log 4.065   ...... and by a log property...... logx^a = (al)ogx      ......so we have

0.4log x = log 4.065       divide both sides by 0.4

log x  = log 4.065/0.4       and, in exponential form, we have

10 ^{log 4.065/0.4}  =   x   = about 33.316

All the possible rational real zeroes are given by all the factors of p divided by all the factors of q where p is 3 and q is 2.

So we have  ±3  ±1  ±3/2  ±1  ±1/2  

And, as Alan found, the only rational real is 1/2.

Notice that the Rational Zeroes Theorem doesn't guarantee any real rational roots. It just says that, if there are any, they will come from the p/q list.

Math is the North American abbreviation of mathematics. Maths is the British abbreviation of mathematics. The British usually abbreviate by including the last letter of the word as well as the first few. This is why the abbreviation for mister is Mr and for missus is Mrs; thus maths.

By the way, the Americans abbreviate mister with Mr. including a full stop, while the Brits only use a full stop at the end of an abbreviation if the last letter is not included.

First, you need to know which points to use. If you are working with coordinates such as (x,y), then you can use the distance formula: $${\mathtt{d}} = {\sqrt{{\left({\mathtt{x2}}{\mathtt{\,-\,}}{\mathtt{x1}}\right)}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\left({\mathtt{y2}}{\mathtt{\,-\,}}{\mathtt{y1}}\right)}^{{\mathtt{2}}}}}$$

This is another way of saying: Find the length between the x coordinates. Then find the length between the y coordinates. Square each length. Add the results together. And then square root the result of adding them. The answer will be the distance between the two points.

The formula comes from the Pythagorean theorem: $${{\mathtt{a}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{{\mathtt{b}}}^{{\mathtt{2}}} = {{\mathtt{c}}}^{{\mathtt{2}}}$$, so you can also draw the points on a graph. Connect the two points to show the distance. Then draw in a right-angle triangle, so the distance between your two points is the hypotenuse (longest side). Then use Pythagoean's theorem.

thank you 

yes .. thats clear 

You can also use a unitary approach.

First calculate what 1% would be worth if 30% is 500. To do this, divide 500 by 30.

$${\frac{{\mathtt{500}}}{{\mathtt{30}}}} = {\frac{{\mathtt{50}}}{{\mathtt{3}}}} = {\mathtt{16.666\: \!666\: \!666\: \!666\: \!666\: \!7}}$$

Then calculate what 100% is worth. To do this, multiply the 1% value by 100.

$${\frac{{\mathtt{50}}}{{\mathtt{3}}}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\frac{{\mathtt{5\,000}}}{{\mathtt{3}}}} = {\mathtt{1\,666.666\: \!666\: \!666\: \!666\: \!666\: \!7}}$$

Rounded off to the nearest whole number, this is 1667.

This can be factored as (2x - 1)(x³ - 3) so there is a zero at the positive rational value 1/2 and at the positive irrational value ³√3.   The other two roots are complex.  There are no negative real roots.
