Answer:
50 being vertically opposite angle
Answer:
3
Step-by-step explanation:
6x - 2w + 9 - 8 = 6x - 2w +1
= 6*2 - 2*5 + 1
= 12 - 10 +1
= 2 + 1 =3

=====================================================
Explanation:
By definition, 
Squaring both sides gets us 
Then multiply both sides by i to get 
Repeat the last step and you should get 
---------------
Notice we have this pattern going on:

Once we reach i^4, we start the process over again.
It repeats every 4 terms.
This means we'll divide the exponent over 4 and look at the remainder. We ignore the quotient completely.
157/4 = 39 remainder 1
That remainder 1 is the exponent of the simplified term

---------------
Similarly,
315/4 = 78 remainder 3
So 
---------------
102/4 = 25 remainder 2

----------------
76/4 = 19 remainder 0

Okay so, this is the slope-intercept form equation:
y=mx+b
m is your slope
and b is your y intercept.
So, taking the equation y= 2/3x+2
2/3 is the slope
2 is the y-intercept
No it is not anything can have 5 sides but not form a pentogon
