The sum of angles in a regular n sided polygon:
(n - 2)*180
(n - 2)*180 = 11520
(n - 2) = 11520/180
(n - 2) = 64
n - 2 = 64
n = 64 + 2
n = 66
Polygon has 66 sides.
Divide by x then is becomes p/x = 4-k
subtracte 4 which makes it -k=p/x -4
then divide by the negative which makes
k= -p/x +4
Y=-3x+5
y=-8x+25
-3x+5=-8x+25
-20=-5x
x=4
y=-3(4)+5=-7
Answer:
If twice the opposite of a number increased by five, then the result is the opposite of a number.
The asiest way to solve this is the guess and check method. It is asking you what a number doubled then by adding five is the opposite of that number. Now go through a few SINGLE digit numbers to try and solve. I hope this helps.
Answer:
B (I think)
Step-by-step explanation:
A function can't have two X values that are the same (If I remember correctly) and the second table is the only one that doesn't have duplicated X values
