I use math-a-way it answers questions like that
9x^2 - y^2 = 1
a.) 18x - 2y dy/dx = 0
2y dy/dx = 18x
dy/dx = 9x/y
b.) y^2 = 9x^2 - 1
y = √(9x^2 - 1)
y' = 9x / √(9x^2 - 1)
c.) substituting y = √(9x^2 - 1) into solution for part a gives
dy/dx = 9x / √(9x^2 - 1)
Thus the two solutions are consistent.
Answer:
For bag C
Step-by-step explanation:
Bag C has more blue marbles than red ones
3x+3+2x=5x-7
5x+3=5x-7
The 5x cancels each other out
3=-7 which isn’t true
