Step-by-step explanation:
To calculate the first 3 terms substitute n = 1, 2, 3 into the n th term formula
(a)
8 - 1 = 7
8 - 2 = 6
8 - 3 = 5
The first 3 terms are 7, 6, 5
(b)
The first negative term wii occur when n > 8, that is n = 9, thus
8 - 9 = - 1 ← first negative term
The one that is on the bottom half and on the right side.
(0,30) to (10,0)
Because the x value 0 represents the time in which the paint job started and ends in the value 10
While the y value 30 is the amount of paint he started with and ends with 0
Here is the graph! I hope this helps!
