Choose the biconditional statement that could be based on the following: P → Q: If a quadrilateral is a parallelogram, then its opposite sides are parallel. Q → P: If its opposite sides are parallel, then a quadrilateral is a parallelogram. Question 1 options: A) P ↔ Q: A quadrilateral is a parallelogram if and only if its opposite sides are parallel. B) P ↔ Q: If a quadrilateral is a parallelogram, then its opposite sides are parallel. C) ∼P → ∼Q: If a quadrilateral isn't a parallelogram, then its opposite sides aren't parallel. D) P → P: If a quadrilateral is a parallelogram, then it's a parallelogram.

A quadrilateral is a parallelogram if and only if its opposite sides are parallel AKA Q⇔P

Step-by-step explanation:

A biconditional statement puts a conditional statement in If and Only if form. it does not negate or switch the hypothesis or conclusion.

The symbol is q arrows going both ways (⇔) p

Hope this helps!!

A quadrilateral is a parallelogram if and only if its opposite sides are parallel AKA QtoP

Step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
