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=36
Step-by-step explanation:
1=0.25
x=9
0.25x=9
divide both sides by 0.25
so x=36
a student can buy 36pencils with 9 dollars
Answer:
5 1/4
Step-by-step explanation:
A) The intersection occurs at the same height 'y', so the y of each equation must be equal:
y=y implies <span>2−x = 8x+4. The solution is -2=9x, x = -2/9=2/3, and y = 20/9
(-2/9,20/9)
</span>
B)
X | Y1 | Y2
_____________
-3 5 -20
-2 4 -12
-1 3 -4
0 2 4
1 1 12
2 0 20
3 -1 28
C) I would draw each line with the values on the table. Where both lines cross is the intersection point. It should be (-2/9, 20/9)
Answer:
No only variable on both sides have no solution
Step-by-step explanation:
Then you can get,
for example x=x
or,
y=y
