Answer:
G. Modus tollens
Step-by-step explanation:
This question used the inference called modus tollens.
Modus tollens is a a valid form of argument that is of this form below:
<em>If S, then T</em>
<em>i</em><em>f not S, then not T.</em>
S = dog doesn't know perpetrator
Not S = dog knows who the perpetrator is
T = the dog barked
Not T = the dog did not bark.
So if we put this into the statement in bold letters, we would have:
The dog doesn't know perpetrator, so it barked.
And,
The dog didn't bark, so it knows the perpetrator.
4 (z - 2) + 2 (z -1)
(4)^(z)+(4)(-2)+(2)^(z)
= 4z+-8+2z+-2
= -4z+-8+2z+-2
=(4z+2z)+(-8+-2)
= 6z+-10
