Answer:
Vertex: (1/2, 16)
Zeros: t = −
1
/2, 3/2
Step-by-step explanation:
First account: $6500
Second account: $8500
Set x is amount of money in first account
=> x + 2000 is money in second account.
X*3% + (x+2000)*4% = 535
=> x = (53500 - 8000) / 7
X = 45500 / 7 = 6500
=> account #1 = x = 6500
Acc #2 = x + 2000 = 6500 + 2000 = 8500
The answer would be 360 :) do you have to show working?
