the equation d=1/2n (n-3) gives the number of diagonals D for polygon with n sides. use this equation to find the number of side
alekssr [168]
To solve this problem you must apply the proccedure shown below:

 1. You have that:

 - T<span>he equation d=1/2(n(n-3)) gives the number of diagonals for the polygon.

 - The polygon that has 65 diagonals..

 2. When you clear n, you obtain:

 d=n(n-3)/2
 d=(n^2-3n)/2
 2x65=n^2-3n
 n^2-3n-130=0
 
 3. When you solve the quadratic equation, you obtain:

 n=13

 Therefore, the answer is: 13 sides.  </span>

What is the slope of this graph?
jasenka [17]

Answer: The slope (m) of the line using two points where the line goes through is:

m = - 4 (negative 4).


Solution:

m=(y2-y1) / (x2-x1)

Taking two points in the graph where the line goes through:

P1=(0,2)=(x1,y1)→x1=0, y1=2

P2=(1,-2)=(x2,y2)→x2=1, y2=-2

Replacing in the formula of the slope:

m=(-2-2) / (1-0)

m=(-4) / (1)

m=-4
