2(4z-9-11)=166-46
8z-18-22=120
8z-40=120
Add 40 from both side
8z-40+40=120+40
8z=160
Divided 8 from both side
8z/8=160/8
z=20. Hope it help!
The contrapositive switches the hypothesis and the conclusion and negates both in this form:
Statement: If A, then B
Contrapositive: If not B, then not A.
In this case, the statement is:
<span> "If the lights are off, there is no one inside."
Contrapositive:
If there is someone inside, the lights are on. </span>
The answer is either c or d. I would go with answer c though. sorry if it is wrong
hi
line equation is : mx+p
so if a line goes throught A(4;6) and with m = 3 so you have 3 *(4) +P = 6
so : 12 +P = 6
P = 6-12
P = -6
line equation is : 3m -6
