the answer is 21ft because the total is 35feet so 35 - 14 = 21

As you can see, if your polynomial or rational function has many factors, the Factor Method can be much faster.

Hello there!
Carol would have sold 60 subscriptions and Jenifer would have sold 30
The correct answer is option D, 60
I hope this help!
The y intercept is 3
You can also say that the y intercept is at (0,3) which is a more detailed answer. However saying "y intercept is 3" is sufficient enough because the x coordinate of the y intercept is always x = 0.
The y intercept is the location where the graph crosses or touches the y axis. This is at the halfway point between the 2 and 4, so (2+4)/2 = 6/2 = 3
