Question

conditional statement:
If both points are positive, then the coordinate point is in the first quadrant.
Which statement represents the biconditional.
1-None of the above.
2-Both points are positive if and only if they are in the first quadrant.
3-If the coordinate point is in the first quadrant, then both points are positive.
-4If the coordinate point is not in the first quadrant, then both points are not positive.

Answer 1

NOA

Answer 2

I think it's 2, right? If and only if implies a biconditional. It's true that the coordinate point is in the first quadrant if both points are positive and it's true that both points are positive if the coordinate point is in the first quadrant.

Answer 3

il let u know if it was correct

Answer 4

Sure :-). But iff is equivalent to \((p \implies q)and (q \implies p)\) so I guess we are safe, haha.

Answer 5

Answer 6
