Select two statements that can form a biconditional.If 6s 7 = 8, then 2r = -2.If 6s+ 8 = -7, then 2r = 0.If 2r= 0, then 6s - 7 = 8.If 8s + 6 = -7, then 2r2 = 0.If 2r2 = 0, then 8s + 6 = -7.If 2r= -2, then 6s+ 8 = -7.

Sagot :

Biconditional is an operation on two logical values, typically the values of two propositions, that produces a value of true if and only if both operands are false or both operands are true.

Making pairs by R as follows

If 6s 7 = 8, then 2r = -2.

If 2r= -2, then 6s+ 8 = -7.

If 6s+ 8 = -7, then 2r = 0.

If 2r= 0, then 6s - 7 = 8.

If 8s + 6 = -7, then 2r2 = 0.

If 2r2 = 0, then 8s + 6 = -7.

checking the pairs by s to see where we can form a biconditional

If 6s 7 = 8, then 2r = -2.

If 2r= -2, then 6s+ 8 = -7.

Not biconditional

If 6s 7 = 8, then 2r = -2.

If 2r= -2, then 6s+ 8 = -7.

Not biconditional

If 8s + 6 = -7, then 2r2 = 0.

If 2r2 = 0, then 8s + 6 = -7.
