80% of 4000 is 3200, so 800 disagreed, and 3200 agreed.
Answer:
I think its the 3rd one...
One factor will be zero, hence y will be zero, when x=-3.
The other factor will be zero, hence y will be zero, when x=-5.
The zeros of the function are x ∈ {-5, -3}.
_____
This solution makes use of the "zero product rule," which states a product is zero if and only if one or more factors is zero.
Answer:
20 stamps
Step-by-step explanation:
Let x be Muthu's original count
Let y be Sangeetha's original count
x = 4y
x - 12 = y + 12
y = x - 24
x = 4(x - 24)
x = 4x - 96
3x = 96
x = 32
so 32 - 12 = 20
