Answer:
C: (3,1)
Step-by-step explanation:
y = -4x² + 24x - 35
y = -4(x² - 6x) - 35
y = -4[x² - 2(x)(3) + 3² - 3²] - 35
y = -4(x - 3)² -4(-9) - 35
y = -4(x - 3)² + 36 - 35
y = -4(x - 3)² + 1

Answer:
$2000
Step-by-step explanation:
6,000 dollars is invested in two different accounts earning 3% and 5% interest.
Let x be the amount invested in account earning 3% interest
So, 6000-x is the amount invested in account earning 5% interest

So, Simple interest for account earning 3% interest


Simple interest for account earning 5% interest



Since we are given that the two accounts earned $220 in interest
So, 




So, 4000 was invested at 3%
(6000-x)=6000-4000=2000 was invested at 5%
Hence 2000 was invested at 5%
