For the answer to the question, <span>what is the probability that he gets a number greater than 2 or an odd number? My answer is
</span><span>all possible rolls are > 2 or odd, except (2), so 5/6
I hope my answer helped you. Feel free to ask more questions. Have a nice day! </span>
This would be the equation:
Y= 5/2x+5
I hope I've helped!
To solve quadratics, the most correct and effective way, in my opinion, is the quadratic formula:
![{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}.}](https://tex.z-dn.net/?f=%7B%5Cdisplaystyle%20x%3D%7B%5Cfrac%20%7B-b%5Cpm%20%7B%5Csqrt%20%7Bb%5E%7B2%7D-4ac%7D%7D%7D%7B2a%7D%7D.%7D%20)
<span><span>
Plugging it in, we get:

![\frac{-4\pm \sqrt{16+72} }{12} = \frac{-4\pm 2\sqrt{22}}{12} = \frac{-2\pm \sqrt{22} }{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-4%5Cpm%20%5Csqrt%7B16%2B72%7D%20%7D%7B12%7D%20%20%3D%20%20%5Cfrac%7B-4%5Cpm%202%5Csqrt%7B22%7D%7D%7B12%7D%20%3D%20%20%5Cfrac%7B-2%5Cpm%20%5Csqrt%7B22%7D%20%7D%7B6%7D%20%20)
So the final answer is:
![\frac{ \sqrt{22}-2 }{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Csqrt%7B22%7D-2%20%7D%7B6%7D%20)
and
The answer is 8 and 13
<span>
y = ax + b
y = 4, x = 1 </span>⇒ 4 = a + b
y = 6, x = 3 ⇒ 6 = 3a + b
Solve the system of equation:
a + b = 4
3a + b = 6
______
b = 4 - a
3a + b = 6
______
3a + 4 - a = 6
2a + 4 = 6
2a = 6 - 4
2a = 2
a = 2/2 = 1
b = 4 - a = 4 - 1 = 3
So, the function rule is: y = x + 3
Thus, if x = 7, then y = 7 + 3 = 10
If x = 10, then y = 10 + 3 = 13
x y
1 4
3 6
4 7
5 8
7 10
10 13
Answer:
the y intercept is -9/2 or -4 1/2
