Part A:
Yes, the data represent a function because there is at least one x-value for every y-value.
Part B:
When x=6 in the input-output table, y=14. When x=6 in the relation f(x)=7x-15, f(x)=7(6)-15=27. <span>The equation has a greater value when x=6.
Part C:</span>
Set f(x) equal to 6 in the equation:
6=7x-15
Solve for x:
7x=21
x=3
<span>x=3 when f(x)=6</span>
7% of 1,000 is 70.
280/70 = 4

Answer:
B. a (n) = -3n + 13
Step-by-step explanation:
Given arithmetic sequence is: 10, 7, 4, 1, -2, ...
Here a = 10, d = 7 - 10 = - 3

Let A = arc length of circle
A = 2πr•(degree/360°)
A = 2π(12)(150°/360°)
A = 24π(150°/360°)
Calculate the right side to find A and you're done. Take it from here.
