Evaluate -6-9÷(-3) ?

Given the relation (2,3), (4,7), (6,11), (x,3), which of the following values of x will make the relation function

Elan Coil [88]

As you said, (x,3) = (2,3)
So x = 2

Thank you very much.

definition of implication: why does P(x) v Q(x) become ~Q(x) -> P(x) rather than ~P(x) -> Q(x)?

insens350 [35]

The easiest way to prove equivalence is to draw out a truth table and then compare the values. I'm going to show a truth table using proposition logic, it's the same result as using predicate logic.
P(x) v Q(x)

P |Q || PvQ || ~Q->P <----Notice how this column matches the PvQ but if you were to
---|---||--------||---------- <----continue the truth table with ~P->Q it would not be equivalent
T T T T
T F T T
F T    T T
F F    F F

Let me know if you would like an example, if the truth table doesn't help.

Jerry was using matrices to solve the system of three equations. He has shown all his steps. Did he make a mistake if so in what

There are several ways to solve a system of equation; one of these ways is the use of matrix.
