If
is true, then
is false, which in turn means
is true.
If
is false, then
is true, and so
is false.
So, because
in both cases, the statement is a tautology (always true).
If you were to put this in a table, you would have one column each for
. In the first column (
) you can think of
as an independent variable that can only take two values, true and false. In the next column (
), you would negate the value in the previous column. And so on.
It should roughly look like this:
p ... ~p ... ~(~p)
T ... F ... T
F ... T ... F
This is a linear function in the slope - intercept form:
y = m x + b and we need a standard form:
a x + b y = c
y = 1/8 x + 7 / * 8 ( we will multiply both sides of equation by 8 )
8 y = x + 56
- x + 8 y = 56 / * ( - 1 )
x - 8 y = - 56
Answer:
Not enough information.
Step-by-step explanation:
The 25 students absent is irrelevant. We still don't know the total number of students at Riverside Elementary School.
