Since it says the sum of any number not one in specific then the value will be x, plus the sum of 7,
Answer:
![Area = 3](https://tex.z-dn.net/?f=Area%20%3D%203)
Step-by-step explanation:
Given
![D = (-4,-4)](https://tex.z-dn.net/?f=D%20%3D%20%28-4%2C-4%29)
![F = (-3,-1)](https://tex.z-dn.net/?f=F%20%3D%20%28-3%2C-1%29)
Solving (a) and (b):
See attachment for plot and labelled vertices
Solving (c): The area
This is calculated using:
![Area = \frac{1}{2}|x_1y_2 - x_2y_1 + x_2y_3 - x_3y_2+x_3y_1 - x_1y_3|](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%7Cx_1y_2%20-%20x_2y_1%20%2B%20x_2y_3%20-%20x_3y_2%2Bx_3y_1%20-%20x_1y_3%7C)
Where:
-- ![(x_1,y_1)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29)
-- ![(x_2,y_2)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29)
-- ![(x_3,y_3)](https://tex.z-dn.net/?f=%28x_3%2Cy_3%29)
This gives:
![Area = \frac{1}{2}|(-4*-4) - (-4*-2) + (-2 *-1) - (-3*-4)+(-3*-4) - (-4*-1)|](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%7C%28-4%2A-4%29%20-%20%28-4%2A-2%29%20%2B%20%28-2%20%2A-1%29%20-%20%28-3%2A-4%29%2B%28-3%2A-4%29%20-%20%28-4%2A-1%29%7C)
![Area = \frac{1}{2}|16 - 8 +2- 12+12 - 4|](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%7C16%20-%208%20%2B2-%2012%2B12%20-%204%7C)
![Area = \frac{1}{2}|6|](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%7C6%7C)
This gives
![Area = \frac{1}{2} * 6](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%206)
![Area = 3](https://tex.z-dn.net/?f=Area%20%3D%203)
Answer:
answer
Step-by-step explanation:
The proper answer to this question is "21378.6".
Reason:
2.13786 *10^4
Answer:
See picture below
Step-by-step explanation:
To graph properly, remember that:
- The y intercept of the function, is the value of the function when x=0, and tells (in this case y=1 is the intercept). Locate this point in the graph.
- The x intercept, which is the value of x when y=0 is x=1. Locate it in the graph.
- You now have two points of a straight line: join this two points and you would have done it!
