For #1 you're just plugging in the numbers that are in the parentheses for x.
For example:
f(2)
Take the given equation to plug in for x:
x^2-4x+5
(2)^2-4(2)+5
And from there you get the answer. Your final answer will look like this:
f(2)=? {the answer you got when you plugged in}
Answer:
Step-by-step explanation:
g^2 - g - 6 = 0 can be factored as such:
g^2 + 2g - 3g - 6 = 0
g(g + 2) - 3(g + 2) = 0
(g - 3) (g + 2) = 0
g = 3, -2
Because g must be less than 0, 3, a positive number greater than 0, cannot be used to solve "-3g". So instead we use the other solution, -2:
-3(-2) = 6, the value of -3g.
Check:
(-2)^2 - (-2) - 6 = 0
(-2)^2 - (-2) = 6
4 - (-2) = 6
4 + 2 = 6
The answer is ![y\geq 2](https://tex.z-dn.net/?f=%20y%5Cgeq%202%20)
Here's how I got my answer:
Step 1: Add 5 to both sides. Which leaves us with ![6y\geq 7 + 5](https://tex.z-dn.net/?f=%206y%5Cgeq%207%20%2B%205%20)
Step 2: Simplify
to 12. Which leaves us to ![6y\geq 12](https://tex.z-dn.net/?f=%206y%5Cgeq%2012%20)
Step 3: Divide both sides by 6. Which leaves us with ![y\geq 12/6](https://tex.z-dn.net/?f=%20y%5Cgeq%2012%2F6%20)
Step 4: Simplify
to 2, do get your answer ![y\geq 2](https://tex.z-dn.net/?f=%20y%5Cgeq%202%20)
Answer:
C: gain

Answer:
The probability the 1st player does not get a blue chracter is 9/14.
Step-by-step explanation:
So there is a total of 14 characters.
9 of them are not blue
9/14 = .642857 (~64%, not the answer since it's not asking for percents)
The probability the 1st player does not get a blue chracter is 9/14.
