Answer:
a) r ⋀~p
b)(r⋀p)⟶q
c) ~r ⟶ ~q
d) (~p ⋀r) ⟶q
Step-by-step explanation:
To solve this question we will make use of logic symbols in truth table.
We are told that;
p means "The user enters
a valid password,”
q means “Access is granted,”
r means “The user has paid the
subscription fee”
A) The user has paid the subscription fee, but does not enter a valid
password.”
Fist part of the statement is correct and so it will be "r". Second part of the statement is a negation and will be denoted by ~p. Since both statements are joined together in conjunction, we will use the conjuction symbol in between them which is "⋀" Thus, we have; r ⋀~p
B) Still using logic symbols, we have;
(r⋀p)⟶q
⟶ means q is true when r and p are true.
C) correct symbol is ~r ⟶ ~q
Since both statements are negation of the question. And also, if ~r is true then ~q is also true.
D) Similar to answer A to C above, applying similar conditions, we have (~p ⋀r) ⟶q
Hello!
<em><u>Answer:</u></em>
<em><u>p<6</u></em>
<em><u>*The answer must have a positive sign and less than symbol sign.</u></em>
Step-by-step explanation:
First, you subtract by 7 from both sides of an equation.
Then, simplify.
Next, multiply by -1 from both sides of an equation.
Simplify.
You can also divide by 2 from both sides of an equation.
And finally, simplify and solve. You can also divide by the numbers.
Final answer: 
Hope this helps!
