Exponential Decay because it’s decaying by .5 which is smaller than 1
Yesss they are SO annoying
No but there's a website where you can calculate what grade you need in order to get a certain grade in the class. Just add the extra credit grade to the grade you have first.
Also, it's extra credit. Why wouldn't you do it? It's FREE points (sort of).
Just copy+paste this URL into your search bar:

Answer: x^2 + 3x - 4
Explanation: I used desmos to double check! This should be right :)
If we subtract the equations we can eliminate the 2 6y's
subtractiong the second from the first:-
10x = 44
x = 4.4
now plug x = 44 into the first equation:-
4*4.4 + 6y = 62
6y = 62 - 4*4.4 = 44.4
y = 44.4/6 = 7.4
the answer is the order pair (4.4,7.4)
