Remember your formula is 180(n-2) where n=number of sides. So start out by dividing by 180, then add 2 to get the sides.
The answer is -12. Do you need to know how I did it?
the table :
(-3,8.5) .....x1 = -3 and y1 = 8.5
(-1,5.5) ....x2 = -1 and y2 = 5.5
slope = (y2 - y1) / (x2 - x1) = (5.5 - 8.5) / (-1 - (-3) = - 3 / (-1 + 3) = -3/2
coordinate plane :
(-3,0), (2,0)
notice how u have the same y values of 0....this means u have a horizontal line where no matter what x is, y will always be 0. A horizontal line has a slope of 0. And ur y intercept is (0,0)
the linear function that is in the table contains a negative slope and also has a steeper slope then the one on the coordinate plane <===
Answer: y= -8
Step-by-step explanation:
- 5( 3y+4) = 6( 2y-2/3)
- 15y+20=12y-4
- 15y-12y=-4-20
- 3y=-24
- y=-24/3
- y= -8
