Question:
Point T, the midpoint of segment RS, can be found using the formulas x = (1/2) (6 – 2) + 2 and y = (1/2) (4 – 6) + 6. What are the coordinates of point T?
Answer:
![T(4,5)](https://tex.z-dn.net/?f=T%284%2C5%29)
Step-by-step explanation:
Given
![x = \frac{1}{2}(6 - 2) + 2](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1%7D%7B2%7D%286%20-%202%29%20%2B%202)
![y = \frac{1}{2}(4 - 6) + 6](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B2%7D%284%20-%206%29%20%2B%206)

Determine the coordinates of T
The coordinates of T can be represented as ![T(x,y)](https://tex.z-dn.net/?f=T%28x%2Cy%29)
To do this, we simply solve for x and y
![x = \frac{1}{2}(6 - 2) + 2](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1%7D%7B2%7D%286%20-%202%29%20%2B%202)
Solve 6 - 2
![x = \frac{1}{2}*4 + 2](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A4%20%2B%202)
Solve 1/2 * 4
![x = 2 + 2](https://tex.z-dn.net/?f=x%20%3D%202%20%2B%202)
![x = 4](https://tex.z-dn.net/?f=x%20%3D%204)
![y = \frac{1}{2}(4 - 6) + 6](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B2%7D%284%20-%206%29%20%2B%206)
Solve 4 - 6
![y = \frac{1}{2}*-2 + 6](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A-2%20%2B%206)
Solve 1/2 * -2
![y = -1 + 6](https://tex.z-dn.net/?f=y%20%3D%20-1%20%2B%206)
![y = 5](https://tex.z-dn.net/?f=y%20%3D%205)
Hence, the coordinates of T(x,y) is:
![T(x,y) = T(4,5)](https://tex.z-dn.net/?f=T%28x%2Cy%29%20%3D%20T%284%2C5%29)
First, the equation for this:
50 + 3x = 250
Now, to isolate variable, -50 on both sides.
50-50 = 0. 250-50 = 200.
3x = 250.
250/3 = 83.3333....
So, round it up. And you get 84 sales
Answer:
neither a or b
Step-by-step explanation:
a function has to have each X have a Y
a domain is paired with exactly one range value.
it has to pass the vertical line test
independent variable is X
dependant variable is Y
student name = x
colors/teachers is Y
so since there is the chance the students can have the same teacher and/or favorite color. then it is not a function
