<span>The sum of the interior angles in an n-gon is
</span>∑<span>angles = 180(n-2)

Since we have a regular 25-gon, all of the angles will be equal in measure.

So, each angle will be: m</span>∠<span>X=180(n-2)/n = 180 x 23/25 = 165.6  deg</span>

Divide £56 in a ratio of 4:3
Kobotan [32]

÷you need to find how many parts there are ;    4 + 3 = <u>7</u>

you then need to divide the number by the parts ; £56  ÷  7   =  <u>£8</u>

<u />1 part = <u>£8</u>

<u />4:3, 4 parts : 3 parts.   

   4  x  £8   =  <u>£32</u>

   3  x   £8  =  <u>£24</u>

<u><em /></u><em>                                            <u>4:3</u></em><u /><u />     =     <em><u>£32:£24</u></em>

<em>to check your answer ;</em>

<em>add both parts of your final answer , £32 + £24  =   <u>£56</u></em><u><em></em></u>

Mr. McKay wrote an algebra test with a total of 15 questions consisting of multiple choice and short response style questions. M
tankabanditka [31]

Step-by-step explanation:

x = number of multiple choice questions

y = number of short response questions

x + y = 15

5x + 10y = 100

=>

x + 2y = 20

let's subtract the first from the second equation :

x + 2y = 20

- x + y = 15

--------------------

0 y = 5

x + y = 15

x + 5 = 15

x = 10

to graph you need to consider both equations as linear functions. and you need to transform them into e.g. a slope intercept form : y = ax + b

a is the slope, b is the y- intercept.

x + y = 15

transforms to

y = -x + 15

this line goes e.g. through the points (0, 15) and (1, 14).

and

x + 2y = 20

transforms to

2y = -x + 20

y = -x/2 + 10

this line goes e.g through (0, 10) and (2, 9).

the crossing point of both lines is the solution and should therefore be the point (10, 5) as calculated above.

Find the inverse of each function. Is the inverse a function? f(x)=x⁷
Luda [366]

The inverse of the function x^7 is x^-7 and it is also a function.

An inverse function or an anti function is defined as a function, which can reverse into another function.

A standard method to find inverse of a function is to set y=f(x)

let y= f(x)=x^7

thus

\sqrt[7]{y}=x

thus f^{-1}(y)=\sqrt[7]{y}

thus f^{-1} (x)=\sqrt[7]{x}

(To verify this if a function is inverse or not we are required to check for the identity)

f(f^{-1}(x))=f^{-1}(f(x))=x

Therefore, The inverse of the function x^7 is x^-7 and it is also a function.
