Answer:
X=30
Step-by-step explanation:
![a + b \: + c + d = \: 360 \\ 3x - 10 + 2x + 8 + 3x + 4x + 2 \\ = 12x = 630 \\ x = 360 \div 12 \\ x = 30](https://tex.z-dn.net/?f=a%20%20%2B%20b%20%5C%3A%20%2B%20c%20%2B%20d%20%20%3D%20%5C%3A%20360%20%5C%5C%203x%20-%2010%20%2B%202x%20%2B%208%20%20%2B%203x%20%2B%204x%20%2B%202%20%5C%5C%20%20%3D%2012x%20%3D%20630%20%5C%5C%20x%20%3D%20360%20%5Cdiv%2012%20%5C%5C%20x%20%3D%2030)

Answer:
3003
Step-by-step explanation:
This is a combination since the order doesn't matter
15 C 10
The formula
15!
-------
10! (15-10)!
15*14*13*12*11
--------------------
5*4*3*2*1
3003
The point-slope form:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
We have the point
and the slope
.
Substitute:
![y-2=\dfrac{1}{2}(x-(-8))\\\\\boxed{y-2=\dfrac{1}{2}(x+8)}](https://tex.z-dn.net/?f=y-2%3D%5Cdfrac%7B1%7D%7B2%7D%28x-%28-8%29%29%5C%5C%5C%5C%5Cboxed%7By-2%3D%5Cdfrac%7B1%7D%7B2%7D%28x%2B8%29%7D)
