Using the function concept, it is found that f is a function, as each student is related to only one GPA and only one number of credits.
In a function, <u>one value of the input can be related to only one value of the output</u>.
In this problem:
- The input is the student.
- The output is the student GPA, and the number of credits earned.
Each student is related to only one GPA and only one number of credits, hence <u>one value of the input is related to only one value of the output</u>, and f is a function.

She earns $400 for 40 hours, so she earns $10 each hour.
6 x 10 = 60
She earns $60 for 6 hours of work.
Answer:
False
Step-by-step explanation:
It is infinitely many solutions
If the equations are not equal, that's when there are no solutions
Infinitely many solutions means that the 2 lines are scalar multiples of each other. They are basically over lapping lines, one of the line just has larger coefficients
EX: x + y = 2
2x + 2x = 4
*These two lines are just scalar multiples of each other. The second equation is just the first equation multiplied by 2. They are the same line.
So any point (x, y) that is on one line is also on the other (these are solutions to the system). There are an infinite amount of points on the line that satisfy the system, so there are infinitely many solutions
Solving this using elimination....
-2x - 2y = -4 (multiply the first equation by -2)
2x + 2y = 4
Now add them....
0 = 0
