Step-by-step explanation:
In a quadratic function, the second differences are the same.
In the first table, the first differences are:
3-6 = -3;
2-3 = -1;
3-2 = 1;
6-3 = 3
The second differences are then:
-1--3 = 2;
1--1 = 2;
3-1 = 2
The second differences are the same, so this is a quadratic function.
Answer:
Step-by-step explanation:
Let x represent the number if months it will take for the total costs of both plans to be the same.
The first plan has $50 signup fee and costs $20 per month. This means that the total cost of using the first plan in a month would be
20x + 50
The second plan has $30 sign up fee and cost $25 per month. This means that the total cost of using the first plan in a month would be
25x + 30
For the costs to be the same,
20x + 50 = 25x + 30
25x - 20x = 50 - 30
5x = 20
x = 20/5 = 4
The costs would be the sane after 4 months. The cost would be
20 × 4 + 50
= $130
