; 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
Let is the answer for the question
For 10 feet and 6 inches,
12 inches = 1 foot, therefore 6 inches = 6/12 foot = 0.5 foot
10 feet 6 inches = 10 + 0.5 = 10.5 feet
7 feet required 3 pints
1 foot would have required (3/7) pints
10.5 feet will then require: (3/7)*10.5 = 4.5 pints.
Therefore 10 feet and 6 inches will require 4.5 pints.
Count by 10s after 27 so continue with 37, 47, 57 until you get past at least 100, which should be 8 times. Therefore it would take 8 weeks of allowance to reach $107
So what makes a function a function is that each input (x) only has one output (y).
Set A is not a function because when x = 2, y = -2 and 3.
Set B is not a function because when x = 9, y = 3 and -3.
In short, the correct option is "Neither A nor B".
