Answer:
x, process, y
-2, -2-1, -3
-1, -1-1, -2
0, 0-1, -1
1, 1-1, 0
2, 2-1, 1
X = -2, -1, 0, 1, 2
Y = -3, -2, -1, 0, 1
Step-by-step explanation:
Coordinates for the graph are ( -2,-3), (-1,-2), (0,-1), (1,0), (2,1)
The graph is the image attached to this.
How to get Y:
-2-1= -3
-1-1= -2
0-1= -1
1-1= 0
2-1= 1
Hope this helps.
Answer:
see below
Step-by-step explanation:
For a point to be on the unit circle, the sum of the squares of the point's coordinates must be 1. Each value that is a fraction will have a square that is smaller than it is.
A: the given values add to 1; the sum of their squares cannot be 1.
B: a correct choice
C: one of the given values is more than 1, so the point cannot be on the unit circle
D: a correct choice
Answer:
24.5
Step-by-step explanation:
A calculator or spreadsheet is good for doing this sort of computation.
_____
You add up the magnitudes of the differences between the given y-value and the corresponding value you get from the equation. For the first couple of points, these values are ...
... |3 - (0.1·1 +2.9)| = 0
... |2.5 -(0.1·6 +2.9)| = |2.5 -3.5| = 1
The computation proceeds like this for the remaining 6 points, and the numbers added. The result is 24.5.
