3, would be 9.75
4, would be 13
5, would be 16.25
6, would be 19.50
7, would be 22.75
8, would be 26
9, would be 29.25
OR 3.25x = y (y being 3-9)
Answer:
B. (1,-8)
Step-by-step explanation:
Slope of the first one:
(-6-0)/(0--3) = -6/3 = -2
y = -2x - 6
3y + 30 = 6x
y + 10 = 2x
-2x - 6 + 10 = 2x
4 = 4x
x = 1
y = -2(1) - 6
y = -8
Answer:
Step-by-step explanation:
hello :
answer C the odd and positif function
The heads probability is ½ and the two’s probability is 1/6. So ½ x 1/6 gives you 1/12. The answer is A. 1/12. Hope this helps.
A polygon has the following coordinates: A(3,1), B(5,3), C(2,5), D(-1,5), E(-4,3), F(-2,1). Find the length of DC.

To find the length of a line given two points, we are going to use the distance formula, which is defined below:
![D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}](https://tex.z-dn.net/?f=D%20%3D%20%5Csqrt%7B%28x_2%20-%20x_1%29%5E2%20%2B%20%28y_2%20-%20y_1%29%5E2%7D)
(
and
are the two points)
The points in this problem are (2, 5) and (-1, 5). We can find the distance of DC by substituting these values into the distance formula and simplifying, as shown below:
![D = \sqrt{(-1 - 2)^2 + (5 - 5)^2](https://tex.z-dn.net/?f=D%20%3D%20%5Csqrt%7B%28-1%20-%202%29%5E2%20%2B%20%285%20-%205%29%5E2)
- Substitute values into formula
![D = \sqrt{(-3)^2}](https://tex.z-dn.net/?f=D%20%3D%20%5Csqrt%7B%28-3%29%5E2%7D)
- Combine like terms and then simplify
to 0
![D = \sqrt{9}](https://tex.z-dn.net/?f=D%20%3D%20%5Csqrt%7B9%7D)
- Compute
![(-3)^2 = 9](https://tex.z-dn.net/?f=%28-3%29%5E2%20%3D%209)
![D = 3](https://tex.z-dn.net/?f=D%20%3D%203)
- Compute
![\sqrt{9} = 3](https://tex.z-dn.net/?f=%5Csqrt%7B9%7D%20%3D%203)
The length of DC is 3.
