W tabeli podano cenniki dwóch korporacji taksówkowych. Należność za przejazd składa się z jednorazowej opłaty początkowej i doliczonej do niej opłaty zależnej od długości przejechanej trasy. Pan Jan korzystał z taxi "jedynka", a Pan Wojciech - z taxi "dwójka". Obaj panowie pokonali trasę o tej samej długości i zapłacili tyle samo

Explanation:

The translated information is:

The mentioned table is:

                                   Taxi 1             Taxi 2

Initial payment           3.20 PLN       8.00 PLN

Price for 1km route    3.30 PLN       2.40 PLN

You can calculate how many kilometers both Mr. Jan and Mr. Wojciech traveled and how much they paid.

You can set a linear equation for each taxi.

The slope-intercept form of a linear equaion is;

Where m is the slope of the line and b is the y-intercept.

The slope is the rate of change of the dependent variable (y) per unit of the independent variable (x), and the y-intercept is the value of the dependent variable when the independent variable is zero.

In this case, you have, that the slopes are the price for 1km route and the y-intercepts are the initial payments. Thus, you have:

            Taxi 1                  Taxi 2

b          3.20 PLN            8.00 PLN

m         3.30 PLN/km     2.40 PLN/km

And the equations are:

Taxi 1                           Taxi 2

You can solve the system by equating the two equations:

Which means that they both traveled 5.33km

To calculate how much they paid you can use any of the two equations:

Which means they paid 20.8 PLN, each.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

you would need to know all the numbers that are on there
