Answer:

{2}

Step-by-step explanation:

Testing out all values:

3(2)+5=11\\\\6+5=11\\\\\boxed{11=11}

The value of 2 works for the equation given.

All other values do not work, as we will result in a contradiction.

3(3)+5=11\\\\9+5=11\\\\14\neq 11\\\\\\3(6)+5=11\\\\18+5=11\\\\23\neq 11\\\\\\3(7)+5=11\\\\21+5=11\\\\26\neq 11

Hope this helps you.

sveticcg [70]

Answer:

a.p→¬q

b.¬p→¬q

c.q→¬p

Step-by-step explanation:

p:You drive over 65 miles per hour

¬p: <em>You do not drive over 65 miles per hour</em>

q:You get a speeding ticket

¬q:<em>You do not get a speeding ticket</em>

(a) You drive over 65 miles per hour, but <em>you do not get a speeding ticket</em>

the first sentence is p and because the consequence is the opposite of q then is no q

p→¬q

(b) If you do not drive over 65 miles per hour, then you will not get a speeding ticket

The first sentence is the opposite of p (¬p), and the second sentence is the opposite of q

¬p→¬q

(c) You get a speeding ticket, but you did not drive over 65 miles per hour.

The first one is q, and the second one is the opposite of p so

q→¬p
