Depends on how much the quiz of your class are worth. The quizzes could represent only %50 of your grade and the rest might be homework
Since y varies directly as x, you know that y=245 and x=7 can be used as a proportion, 245/7. When you multiply this proportion to 9, you get 315. This is the value of y when x=9.
y=315
Answer:
(0,-8/3)
Step-by-step explanation:
2x-3y=8
x-3y=8
Multiply the second equation by -1 and add together
2x-3y=8
-x+3y=-8
---------------------
x +0y =0
x=0
Now we can find y
2x -3y =8
0-3y =8
Divide by -3
-3y/-3 = 8/-3
y = -8/3
(0,-8/3)
Answer:
It's the second option -> y = 1/2x -1
