Step-by-step explanation:
7. 180 -92 -67 =21. 180-21 = 159
8.180-144 = 36 + 94 = 130 180-130 = 50
; a₁ is the first term, d is the difference between terms, and n is the term
-4, -21, -38, ... ⇒ a₁ = -4, d = -17
= -4 - 17n + 17
= 13 - 17n
= 13 - 1088
= 1075
Answer: 1075
Parallel means the slopes are the same
Perpendicular means they have opposite reciprocal slopes.
We can apply these concepts to this question. Although they are opposites of each other, they are not reciprocals.
So, the answer is neither
Hope this helps!
