calculus 

x.(a-b)-y.(a-b)/x-y= x-y.(a-b)/x.y = a-b

Nevermind I found how

(ax-bx-ay+by ) / (x-y)

(x (a-b) -y (a-b) ) / (x-y)

((x - y ) ( a - b ) )/ (x-y)

a - b

(x - 1)(x² - 9x + 18)  <=  0

Don't expand; separate the parts:

For  (X)(Y)  <=  0,  there are two possibilites:

Either  X is positive  and  Y is negative

or         X is negative  and  Y is positive.

So:

Either  (x - 1 ) >= 0  and  (x² - 9x + 18)  <=  0

or         (x - 1 ) <= 0  and  (x² - 9x + 18)  >=  0.

Case 1:  (x - 1 ) >= 0  and  (x² - 9x + 18)  <=  0

                 x - 1  > = 0  and    (x - 6)(x - 3)  <= 0

                      x  >=  1   and     3  <=  x  <= 6

                                 3  <=  x  <=  6

Case 2:  (x - 1 ) <= 0  and  (x² - 9x + 18)  >=  0

                 x - 1  <=  0  and     (x - 6)(x - 3)  >= 0

                      x  <=  1  and    [  x  <=  3  or  x  >=  6  ]

                                  x  <=  1

x = 6!!!!!!!!!!

(x-1) (x-6)(x-3) = 0     Now x = 1  6  or 3

Sorry double post, please answer on the more recent thread -___-

D**n but now I cannot find the other thread because it's been deleted...

I will assume store A sells 4 gallon containers ...not 44 gallon.

$148/4 gal   /   1296sqft/gal /4gal  = $ .11419 sqft

Store b

       $(9.25x4)/1 gal    /   (81 x4)sqft/1 gal =$ .11419  sqft

They are the same price per sq ft of coverage

All three sides have to total 57 cm

Side 1    3x-6

         2   2x+12

         3    2x+9

Add them together, equate to 57 and solve for 'x'

3x-6  + 2x+12  +  2x+9 = 57     Add 'like' terms

7x +15 = 57       subtract 15 from both sides

7x = 42

x = 6

Side 1 = 3(6)-6 =12 cm

Side 2 = 2(6) + 12 = 24 cm

Side 3 = 2(6)+9 = 21 cm

Ignore this solution.....it is incorrect.....I misread the equation.

2^(x^2)  * 4^x * 2^-15 = 1      is correctly solved by Guest in the previous post !!!!    x  = 3 or -5

you left out an 'a' in Harambe 's  name.....just sayin'

We don't need ALL of these ordered pairs to get the slope....

let's just use the first two

y=mx+b   is the equation of a line where  m= slope   and b = y-intercept

slope = m = (y2-y1)/(x2-x1) = (0-8)/(0-(-2)) = -4   slope

y=mx+b     reults in   y = -4x + b     if we sub in a point  (-2,8)   we will find b=0  which is the y-intercept

so your equation of the line becomes    just  y= - 4x       You can substitute in the other ordered pairs to see if they 'fit' (they do)

D'oh!  I just looked at this again.....one of the ordered pairs is 0,0   <------ obviously this is the y-intercept ! (AND the x-intercept)......   Sorry for making this more complicated than it needed to be....

Agree with Guest......after doing whatever computations are between the absolute value bars  |      |   the result is always the POSITIVE of that value....

Do you have the equation 'h' is used in...because it can be   a  b  or c

As a variable   l x w x h = volume

h= 6.62607004 × 10-34 m2 kg / s     is Planck's constant

hx^2 + x - 2 = 0    it is a coefficient    

I got x=0.426302751007

If you use the calculator you will get   sqrt(69) = 8.3066238629180749

10/60  = 15/90   (they BOTH equal 1/6 when simplified)

10/60  x  1.5/1.5   = 15/90

When a number is in absolute value then the final result of the equation inside is NOT negative, it will be positive as in |5-8| = 3, and not negative 3

An SI unit of volume   = 1000 ml    or  33.814 US fluid oz

What is 17/2 lb and 3/4 gal as a unit rate?

\(\frac{\frac{17}{2}lb}{\frac{3}{4}gal}=11{\frac{1}{3}}\frac{lb}{gal}\) 

\(\large11{\frac{1}{3}}\frac{lb}{gal}\)\(\times\)\(\LARGE\frac{\frac{1kg}{m^3}}{\LARGE\frac{0.010022413122466\ lb}{gal}}\) 

\(11{\frac{1}{3}}\frac{lb}{gal}\) \(=1130.79885999\ \frac{kg}{m^3}\)

\(Density \ of \ air \ at \ 1013 \ hPa \ and \approx 100grd \ Celsius.\)

Thank you very much.
