The number of people contacted at each level of a phone tree can be
represented by f(x) = 3, where x represents the level.
What is x when f(x) - 27?
A. X = 2; At level 2, 27 people will be contacted.
B. x 24; At level 24, 27 people will be contacted.
c. x = 3; At level 3, 27 people will be contacted.
D. X = 9; At level 9,27 people will be contacted.

Do not comment if you aren’t going to . create a real-life situation and create a system and show how it might be modeled algebraically with a system of equations (or inequalities) show all work include a few sentences explaining the situation, your variables of choice and what each represents, and how you would set it up and solve it algebraically. !

Which equation represents the partial sum of the geometric series?

Find the value of x for which the lines are parallel.
