Answer:
-3×5/-5=15-5=5
Step-by-step explanation:
-12/-5= 2. 1/2 answer
She will earn $91.80. this is because 12 hours and 45 minutes is 12.75 hours and to find the total amount made we need to do 12.75× 7.20 which is 91.8
3. Cost it is a practice that you have a good day and I don’t want you in to the house but you can tt it up and you have to do a
Y=3x-2 because (0,-2) is the y intercept (b) and m is the slope.
Answer:
The statement
is a tautology.
![p\rightarrow (q\rightarrow p)\equiv \lnot p\lor (q\rightarrow p) \equiv \lnot p\lor (\lnot q\lor p) \equiv (p\lor \lnot p) \lor \lnot q \equiv T \lor \lnot q \equiv T](https://tex.z-dn.net/?f=p%5Crightarrow%20%28q%5Crightarrow%20p%29%5Cequiv%20%5Clnot%20p%5Clor%20%28q%5Crightarrow%20p%29%20%5Cequiv%20%5Clnot%20p%5Clor%20%28%5Clnot%20q%5Clor%20p%29%20%5Cequiv%20%28p%5Clor%20%5Clnot%20p%29%20%5Clor%20%5Clnot%20q%20%5Cequiv%20T%20%5Clor%20%5Clnot%20q%20%5Cequiv%20T)
Step-by-step explanation:
We have the following statement:
![p\rightarrow (q\rightarrow p)](https://tex.z-dn.net/?f=p%5Crightarrow%20%28q%5Crightarrow%20p%29)
To reduce the statement to a tautology we need to use the table of logical equivalences as follows:
![p\rightarrow (q\rightarrow p)\equiv](https://tex.z-dn.net/?f=p%5Crightarrow%20%28q%5Crightarrow%20p%29%5Cequiv)
by the the logical equivalence involving conditional statement.
by the the logical equivalence involving conditional statement.
by the Associative law.
by the Negation law.
by the Domination law.
