Parallel lines have to have the same slope. The must stay the same distance apart at all times to be parallel and the only way to do that is to change in exactly the same manner as they move so slope is the change in x over the change in y. it must be the same
x is time and y is pencils that you have
'starts with 90' so at x=0, plot y=90
'gives away 15 every hour' so for every 1 hour, move 15 down on y
so at x=1, do 90-15=75 pencils
at x=2, do 75-15=60 pencils
etc
until you get to
x=6, do 15-15=0 pencils then stop because you can't give away 15 pencils when you have 0
see attachment for plot
I don't know how your segment tool works so you do it
if it draws a line, you only need 2 points, just do when x=0, y=90 and when x=6, y=0
Answer:
18
Step-by-step explanation:
36/4=9 9/2=4.5 4.5+4.5+4.5+4.5=18
Plug in 3 for n, since you're looking for the third term.
T(1) = 3(1) - 1 = 2
T(2) = 3(2) - 1 = 5
T(3) = 3(3) - 1 = 8
It would be 8.
The answer to this is -8/3
