Answer:
7,840,000
Step-by-step explanation: 7,842,501 is closer to 7,840,000 than it is to 7,850,000.
To write this function in function notation all you would need to do is rearrange the equation for y.
3x + 2y = 12
3x - 3x + 2y = 12 - 3x
2y = 12 - 3x
2y/2 = 12/2 - 3x/2
Y = 6 - 3/2 X or
Y = -3/2 X + 6.
P=1
p^4+p^2+p-k=0
1+1+1-k=0 k=3
