Answer:
(-2, 0), (-3, 0), and (5, 0)
Step-by-step explanation:
The x-intercept is found when <em>y = 0</em>.
So, we have to find x when <em>(x + 2)(x + 3)(x - 5) = 0</em>
We can do that by pulling apart all parts, because if one part = 0, the whole thing will have to be too (multiplication property of identity).
1. When x + 2 = 0, x = -2
2. When x + 3 = 0, x = -3
3. When x - 5 = 0, x = 5
That gives us (-2, 0), (-3, 0), and (5, 0)

Answer:
179 minutes
Step-by-step explanation:
You can write an equation to represent the cost of the rental, and then you can solve the equation to find the number of hours.
Let m = number of minutes.
The total cost is the cost per minute plus the fee to start.
1 minute costs $0.12.
2 minutes cost $0.12 * 2
x minutes cost $0.12 * x, or simply 0.12x.
The fee to start is $2, so the total to rent for m minutes is 0.12m + 2.
The equation
c = 0.12m + 2
gives you the cost, c, for a rental of m minutes.
We are told the total cost was $23.48. Replace c with 23.48, and solve for m, the number of minutes.
23.48 = 0.12m + 2
Switch sides.
0.12m + 2 = 23.48
Subtract 2 from both sides.
0.12m = 21.48
Divide both sides by 0.12
m = 21.48/0.12
m = 179
