Oliga [24]2 years ago
3 0

Answer:

a => b   \equiv   ( \neg a   \ \lor   \ b )

Step-by-step explanation:

You can understand the statement from many perspectives, but in terms of proposition logic it is best to understand it as   "negation of a" or "  b" in mathematical terms is written like this

a => b   \equiv   ( \neg a   \ \lor   \ b )

You can show that they are logically equivalent because they have the same truth table.

gavmur [86]

Answer: the amount by which her lunch account would have been impacted is $45

Each day Valerie charges her lunch account for her lunch. If the cost of lunch is $3 then, it means that Valerie charges the lunch account with $3 daily. It means that in x days, she would have charged her lunch account with 3×x = $3x

If she charged her account for a period of 15 days, it means that x = 15. Therefore, the amount by which her lunch account would have been impacted is 3×15 = $45

AURORKA [14]
So D would be going up because it is positive. It is going up 10ft, once again cause the integer is a positive 10. Now E will be going down because it is a negative. Therefore it will go down 15ft for the reason being the integer is negative 15. Hope this helps.

Which set of ordered pairs represents a function?
Lemur [1.5K]
It would be D, because to be a function, a set of ordered pairs cannot have the same x value. The y value can be the same though.
(5,6), (8,6), (9,6) 
As you can see, all of the x values are different, so it is a function.
