Answer:
First relation: It's a function. No order pair need to be changed.
Second relation: It's a function. No order pair need to be changed.
Third relation: It's not a function. The ordered pair (5,8) needs to be changed.
Step-by-step explanation:
A function may not have two y-values assigned to the same x-value.
Each x-element of the first relation has only one y-element associated with it. So we conclude that it's a function.
Each x-element of the second relation has only one y-element associated with it. So we conclude that it's a function.
The points (5,8) and (5,2) shows that there are two y-elements (y=8 and y=2) associated with the value x=5. So we conclude that it's not a function.

Answer:
The anwser is B
Step-by-step explanation:
yes, because you need to convert the repeating number into a decimal. In this case, you can assume that x is the fraction form of 0.7 repeating.
I believe it’s C, hopefully this helps !!
Answer:
each side of the hexagon measures 40 cm (which agrees with answer B)
Step-by-step explanation:
Recall that a regular hexagon has six equal sides, therefore, each side would be one sixth of the 240 cm:
each side of the hexagon = 240 cm / 6 = 40 cm
