Answer: A good way to determine if a line represents a valid function is to use the vertical line test.
To do this, you imagine a vertical (up and down) line moving across your graph from left to right. It should only be touching the line at one point at a time.
If it is touching more than one point on the line at a time, the line is not a valid function.
The first line and its inverse both pass the test.
The second line passes the test, but its inverse does not.
The third line also passes the test, but again, its inverse does not.
The same applies to the fourth line and its inverse.

Answer:
3:20
Step-by-step explanation:
The 360 degrees clockwise rotation of the minute hand corresponds to 60 minutes.
The 90 degrees clockwise rotation is one-fourth of the 360 degrees, and hence will corresponds to 15 minutes.
The time is now 3:05.
After 15 minutes the time will be 3:20
Therefore the teacher dismisses the class at 3:20
Answer:
48 and 32 6 hours clearing tables and 2 hours tutoring
Step-by-step explanation:
we can rewrite this as a fraction. we will use 1/10s because 80 can be divided by 8 which is in the problem. we then have to find out what two numbers add up to 8 but one is 3 times the other. 6 and 2 fit into this problem so we plug it into the equation and we write it as this 6x+4x=80 where x is 8. we get 48 and 32.
