Answer: Point W
Its the Only interior point.
A quadratic with roots at 8 and 5 is f(x) = x^2 +12x + 20
In order to find an equation given roots you can create statements that equal 0 in order to create parenthesis. For instance we know x = 8 at one point. So, we can solve that to equal 0.
x = -2 ----> add 2 to both sides
x + 2 = 0
We can do the same for the other zero.
x = -10 ----> add 10 to both sides
x + 10 = 0
Now that we have both of these, we can multiply these two things together. This will give us the function we need.
f(x) = (x + 2)(x + 10)
f(x) = x^2 + 10x + 2x + 20
f(x) = x^2 + 12x + 20
The correct answer is C: y > 2/3x + 3
(1,4) ⇒ within the shaded region
4 > 2/3(0) + 3
4 > 0 + 3
4 > 3
True
(0,0) ⇒ within the unshaded region
0 > 2/3(0) + 3
0 > 0 + 3
0 > 3
False
Answer:
990
Step-by-step explanation:
There are 11 members in the club.
President can be chosen in 11 different ways, then 10 members left.
Vice President can be chosen in 10 different ways, then 9 members left.
Secretary can be chosen in 9 different ways.
Thus, President, Vice President, and Secretary be chosen in
different ways.
