Create a truth table and prove that for any statement p, ~(~p) equals p. (said it should be a 3 by 3 table with p; ~p; ~(~p ) at
the top?) I gotchu with 20 points
1 answer:
Answer:
Truth value of ~(~p) is same as the truth value of p.
Step-by-step explanation:
For any statement p the truth table for p, ~p and ~(~p) will be as the figure attached. In this table we know that If truth value for p is true then ~p will be false and ~(~p) will be true which is same truth value as truth value of p.
Now if the truth value of any statement is false then truth value for ~p will be true and for ~(~p) will be false which is again similar to the statement p.
Hence truth value of any statement p is similar to the truth value of ~(~p).

A linear equation is an equation of a line while a system of linear equations contains two or more linear equations that work together. A system of two linear equation has no any solution when the lines have the same slope. The graphed line shown in the Figure has an equation being the slope
. Thus, from the options the line that has the same slope is
. Finally, these two lines have no any because they are parallel.
