This is known as a piecewise function. It's a function that depends on what t is valued at. There are three cases
If
then f(t) = 0. This means that for the first 30 minutes, the cost is $0, in other words the first half hour is free.
If
then f(t) = 5 indicating that the cost is $5 for the entire span from 30 minutes to 90 minutes (excluding t = 30 but including t = 90). Choice B is not the answer because the cost isn't $5 per minute. The cost for this entire timespan is simply $5
Finally, if t > 90, then f(t) = 10 telling us that any time value over 90 minutes will have the cost be $10. This is why
the answer is choice D
3y=-2x+12
y=-2/3x+4
the slope -2/3
Answer:
D) 4x1 = 4

Answer:
x = 10
Step-by-step explanation:
The total length of segment PS is 52. To solve for x, we can simply add 5x (which is the length of segment PR) and x-8 (which is the length of segment RS) together and make the equation equal to 52 to solve for x.
- 5x+x-8 = 52
- 6x - 8 = 52
- 6x = 60
- x = 10
