Which direction are they going? 

Since there are 60 minutes in an hour, 120 minutes will be two hours from now.

12:51 + 2:00  =  14:51  (or 2:51)

x² - 5x + 6

Since the last term (+6) is positive, the two signs will either be both positive or both negative.

Since the middle term (-5x) is negative, the two signs will be both negative.

The form of the answer is:  (x -    )(x -    )

The last term, 6, can be factored either as 1 and 6 or 2 and 3.

Trying  (x - 1)(x - 6), when foiled, becomes x² - 7x + 6, which isn't correct.

Trying  (x - 2)(x - 3), the answer becomes x² - 5x + 6 !!!!!!!!!!!!!!!!!!!

Working with the real term first:

     3(-2) - 4   =  -6 - 4  = -10

Now, the imaginary term:

     ( 1 - 2(-2) )  =  ( 1 + 4 )  =  5

Putting these toether:     -10 + 5i

The 4 represents amplitude.

The +5 represents a horizontal shift.     ***

The +3 represents a vertical shift.        ***

A change in period  would be represented by a multiplier of the x term, as in:  y  =  sin(3x), which Since this problem as simply x, or 1x, there is no increase or decrease in the period.

Hint:  the '+ π/4' give the graph a horizontal shift of π/4 to the left.

So, find the x-intercepts of the function  f(x) = sin(x) and subtract π/4 from each of these x-values.

The price is calculated by multiplying the price per pound times the number of pounds.

So:  p  =  3.99 · w

Let the number of dimes be:  d

Then, since the number of quarters is two less than the number of dimes:  q = d - 2

The number of nickels is twice the number of quarters:  n = 2·q  =  2(d - 2)  = 2d - 4

Since there are 40 coins,  p + n + d + q  =  40

                               or:   p + (2d - 4) + d + (d - 2)  = 40

               Solving for p:    p  + 4d - 6  =  40         --->      p  =  46 - 4d

 .01(46 - 4d) + .05(2d - 4) + .10(d) + .25(d - 2)  = 3.86

Multiply by 100:

       (46 - 4d)  +  (10d - 20)  +  (10d)  +  (25d - 50)  =  386

                       41d  -  24  =  386

                                41d   =  410

      --->  d = 10

Use this to find the other answers and check the work.

Use the distributive property on   x(1-3x)  to get  x·(1) - x·(3x)

      x·(1)  = 1x or just x

      x·(3x)  =  3·x·x  = 3x²

So   x(1-3x)  =  x - 3x²

Now: x(1-3x) + 3x - 1  =  x - 3x² + 3x -1

To simplify this:  x + 3x  = 4x

So, the answer is: - 3x² + 4x -1

Assuming you wanted to put this into Scientific Notation, you would put a decimal point after the first "2" and type it in the calculator.

DS do you still need a poem for a " pet rock"?

i was thinking to write one!

what a nice poem!even i cant write this good!and i didnt even came to know when kitty became a princess!aww even i wanna be one .......

Base three:  11

Base five (or any base greater than five:  4

x + 1/3  =  5 + x/2

Oftentimes, equations are easier to solve if there are no fractions.

To get rid of fractions, multiply each side by a common denominator (a common denominator of 3 and 2 is 6).

6 · (x + 1/3)  =  6 · (5 + x/2)

6 · x  +  6 · 1/3     =     6 · 5  +  6 · x/2

6x  +  2    =    30 + 3x

Get all the x's to one side (subtract 3x from both sides);

6x - 3x + 2  =  30 + 3x - 3x

3x + 2  =  30

Subtract 2 from both sides:

3x + 2 - 2  =  30 - 2

3x  =  28

Divide by 3:

x  = 28/3   or   9 1/3

It is just 21r^3.

You can set up a proportion:     time / distance  =  time / distance

      28 min / 8 mi    =    x / 15 mi

Cross multiply:

     8 · x  =  28 · 15     --->     8x  =  420     --->     x  =  

To estimate the correctness of your answer since 15 min is a little less than twice 8 min, your answer should be a little less than twice 2 min.

A positive times a negative is negative.

The rules of operation tells us to do multiplications before addition.

0,5 * -3  =  -1,5

-3 * 3  =  -9

-1,5 - 9 + 3  =  -7,5  

This question can lead to some serious stuff  --

For instance if nothing is something, then it can't be nothing anymore ...

But, if nothing is nothing, by the fact that it "is", it must exist, therefore it is something and one's brain begins to explode ...

But, Western thought (possibly horrendously) is continually brought back to the work of Plato and Aristotle and their ideas. Aristotle's work on Logic, provided only two possibilities, true or false, and this influence exists to this day, even though mathematical logic provides with greater possibilities.

There was no symbol for zero in Western mathematics until past the Middle Ages, partially due to the philosophy (which was backed by religion) that if you gave "nothing" a symbol, it became something and then you are messing with God's creation and then you are in deep trouble.

Possibly, the question "Is nothing something?" is confusing only because our brains haven't been sufficiently developed to answer this question, or that the creation of our language made this a confusing question.

Actually, if you read a little about modern physics with its quantum mechanics, you read about items that are both here and there and wherever, all at the same time.

So, keep asking strange questions because then you are invited into strange, and marvelous places.
