13.3
Since 3 is LESS than 5 we round down to 13.
Answer:
The answer to your question is: letter B
Step-by-step explanation:
A) No, it is not a function because it has two open circles.
B) Yes, it is a function because it passes the vertical line test.
C) Yes, it is a function because it passes the horizontal line test.
D) No, it is not a function because it does not pass the horizontal line test.
Check the picture below.
so as you already know, a rhombus is a parallelogram whose sides are equal, so the distance from say (-10, 1) to either endpoint of the other diagonal must be the same.
