Answer:
f(3) = -11
Step-by-step explanation:
f(x) = -3x - 2
f(3) = -3(3) - 2 = -9 - 2 = -11
A=3
B=-33
C=54
Plot it into the Quadratic equation which is -b +- Square root of: b^2 -4ac.Divided by 2a.
You can find you answer when you plot it into this! If you do not get what the Quadratic equation is check online.

Answer:
Increase by 72.5 percent
Step-by-step explanation:
Just dived 435 by 600 and you get your answer
There are 14 chairs and 8 people to be seated. But among the 8. three will be seated together:
So 5 people and (3) could be considered as 6 entities:
Since the order matters, we have to use permutation:
¹⁴P₆ = (14!)/(14-6)! = 2,162,160, But the family composed of 3 people can permute among them in 3! ways or 6 ways. So the total number of permutation will be ¹⁴P₆ x 3!
2,162,160 x 6 = 12,972,960 ways.
Another way to solve this problem is as follow:
5 + (3) people are considered (for the time being) as 6 entities:
The 1st has a choice among 14 ways
The 2nd has a choice among 13 ways
The 3rd has a choice among 12 ways
The 4th has a choice among 11 ways
The 5th has a choice among 10 ways
The 6th has a choice among 9ways
So far there are 14x13x12x11x10x9 = 2,162,160 ways
But the 3 (that formed one group) could seat among themselves in 3!
or 6 ways:
Total number of permutation = 2,162,160 x 6 = 12,972,960
