Y=ax+b
3=-8(0)+b
3=0+b
3=b
Y=-8x+3
(I think this is right, but u might want to double check)
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.

The answer is going to be A.
---------------------------------------------
Formula
---------------------------------------------
Sum of all exterior numbers = 360°
---------------------------------------------
Apply Formula
---------------------------------------------
z + 45 + 55 + 78 + 74 + z = 360
---------------------------------------------
Combine likes term
---------------------------------------------
2z + 252 = 360
---------------------------------------------
Take away 252 from both sides
---------------------------------------------
2z = 360 - 252
2z = 108
---------------------------------------------
Divide by 2 on both sides
---------------------------------------------
2z = 108
z = 108 ÷ 2
z = 54
---------------------------------------------
Find z + 45
---------------------------------------------
z + 45 = 54 + 45
z + 45 = 99°
---------------------------------------------
Answer: 99°
---------------------------------------------
I believe the answer would be "infinitely many solutions" because you can put any number as x and y would be a different answer each time for both of the equations given. i hope this helps :)
