Answer:
The first plan of $49 will be best plan for her.
Step-by-step explanation:
Katherine used 1479 minutes call in the last 6 months.
So, the average monthly call that Katherine made is 
minutes.
Now, there are two plans for mobile recharge.
One is 250 minutes call time for $49 and the other is 350 minutes call time for $65.
Since 246.5 < 250 and Katherine does not want to spend more for minutes she won't use, then the first plan of $49 will be the best plan for her. (Answer)
<h3><u>Question</u> :-</h3>
Is (x-2) is a factor of x³-3x²-x +7 –
<h3><u>Explanation</u> :-</h3>
We are given –
- Polynomial function, P(x) = x³-3x²-x +7
- In order to check if x - 2 is a factor of x³-3x²-x +7 or not, we must show that P(2) = 0.
Now Put x = 2 into the polynomial –
- Since the value of the polynomial function st x = 2 is not Zero (0). Henceforth, ( x - 2) is a factor of x³-3x²-x +7.

U can either look at ur graph...and where the line crosses the x axis is ur x intercept...which is (-3,0)
OR
take ur equation and sub in 0 for y, and solve for x, ur x intercept.
2x - y = -6
2x - 0 = -6
2x = -6
x = -6/2
x = -3.....so ur x intercept is (-3,0)
