Answer:
x = -7
Step-by-step explanation:
-2x - 10 = 4
-2x = 14 | Add 10 to both sides
x = -7 | Divide both sides by -2
Answer:
1.45934 × 10^5
Step-by-step explanation:
First you need to find out what times 4 equals 8. You should know that it is 2 because 2×4=8. Then it should look like this
![8 \sqrt{8}](https://tex.z-dn.net/?f=8%20%5Csqrt%7B8%7D%20)
and that should be your answer or what ever your problem says to do.
Hope this helped :)
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).
