Step-by-step explanation:
Answer: 286 minutes
Step-by-step explanation:
x : # of months that has gone by
0.24x : cost of the 24 cent plan after "x" minutes
39.95 + 0.10x : cost of the 10 cent plan after "x" minutes
1. 39.95 + 0.10x > 0.24x
2. 39.95 > 0.24x - 0.10x
3. 39.95 > 0.14x
4. 285.36 > x
x must be AT LEAST 286 minutes for plan #2 (39.95 + 0.10x) to be a better deal
She did not simplify under the square root correctly.
<h3>Quadratic equation</h3>
Given the quadratic expression
5x^2 - 6x - 8 = 0
Using the general formula, we will have:
From the given equation;
a = 5
b -6
c = -8
Substitute the values into the formula to have:
From the given solution, we can see that she did not simplify under the square root correctly.

Hi,
c(x) is a linear function, if you graph it, you obtain a straight line.
The slope is the coefficient of x, therefore the slope is 2.
When the ride starts (x = 0), the start cost is 4 dollars (or whatever the currency is), then every minute spent on the moving taxi, as many as 2 dollars need to be paid to taxi driver.
I hope these help.
