Answer:
The coordinates of point E are (7,8).
Step-by-step explanation:
Point E:
Is given by (x,y).
DE: EF = 2:3.
This means that, for both coordinates x and y:
![E - D = \frac{2}{2+3}(F-D)](https://tex.z-dn.net/?f=E%20-%20D%20%3D%20%5Cfrac%7B2%7D%7B2%2B3%7D%28F-D%29)
![E - D = \frac{2}{5}(F-D)](https://tex.z-dn.net/?f=E%20-%20D%20%3D%20%5Cfrac%7B2%7D%7B5%7D%28F-D%29)
x-coordinate:
x-coordinate of D: 1
x-coordinate of F: 16
![E - D = \frac{2}{5}(F-D)](https://tex.z-dn.net/?f=E%20-%20D%20%3D%20%5Cfrac%7B2%7D%7B5%7D%28F-D%29)
![x - 1 = \frac{2}{5}(16-1)](https://tex.z-dn.net/?f=x%20-%201%20%3D%20%5Cfrac%7B2%7D%7B5%7D%2816-1%29)
![x - 1 = 2*3](https://tex.z-dn.net/?f=x%20-%201%20%3D%202%2A3)
![x = 7](https://tex.z-dn.net/?f=x%20%3D%207)
y-coordiante:
y-coordinate of D: 4
y-coordinate of F: 14
![E - D = \frac{2}{5}(F-D)](https://tex.z-dn.net/?f=E%20-%20D%20%3D%20%5Cfrac%7B2%7D%7B5%7D%28F-D%29)
![y - 4 = \frac{2}{5}(14-4)](https://tex.z-dn.net/?f=y%20-%204%20%3D%20%5Cfrac%7B2%7D%7B5%7D%2814-4%29)
![y - 4 = 2*2](https://tex.z-dn.net/?f=y%20-%204%20%3D%202%2A2)
![x = 8](https://tex.z-dn.net/?f=x%20%3D%208)
The coordinates of point E are (7,8).
Answer:
The best way to show and explain direct proportional relationships is by graphing two sets of related quantities. If the relation is proportional, the graph will form a straight line that passes through the origin.
Step-by-step explanation:
Each person payed $175
First add the cost up:
$900 on transportation + $500 hotel room= $1400 total
8 people paying $1400 means divide 1400 by 8 to see how much one person payed.
1400/8 = 175
Each person payed $175
Answer:
3. $3 + (5 * $3) = a, that is the answer
