Answer:
C
Step-by-step explanation:
if you don't have from same x different outcomes is a function
think that x is a day you count votes, you can not get for the same day different y number of votes ( something is fishy then)
A. not a function because (6, -3) and (6, 3)
B. not a function because (4,7) and (4,2)
C. is a function
D. not a function because (2, -1) (2,1) (2,3)
I believe its 4 we haven't really went over it
At the end of the directions, it talks about parallel, perpendicular, or neither. When x=y, the lines are perpendicular and have infinite solutions. When they are parallel, there is no solution. You'll get an answer like 4=5. Neither means there is only one answer, and you will get one x and one y.
Answer:
A,C, and D I believe.
Step-by-step explanation:
Answer: (3 , 7)
Step-by-step explanation: When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative. Since x and y are already negative, they become positive due to the double negative rule.
