Describe and correct the error a student made in finding the midpoint of CD with ​C(​4,5) and ​D(​1,​4).
Andru [333]

Using the given information, the midpoint of CD is (2.5, 4.5)

<h3>Midpoint of a line </h3>

From the question, we are to determine the midpoint of line CD

The midpoint of a line is given by the formula,

[(x₁ + x₂)/2 , (y₁ + y₂)/2]

From the given information, we are to find the midpoint of line CD with coordinates C(​4,5) and ​D(​1,​4)

∴ x₁ = 4

x₂ = 1

y₁ = 5

y₂ = 4

Putting the parameters into the formula for midpoint, we get

[(x₁ + x₂)/2 , (y₁ + y₂)/2]

[(4 + 1)/2 , (5 + 4)/2]

(5/2 , 9/2)

(2.5, 4.5)

Hence, the midpoint of CD is (2.5, 4.5)

so uh i have a question about STEAM the app ik this is a math website but uh my question is lets say your playing roblox or mine
yawa3891 [41]

Answer:

Step-by-step explanation:

First off, steam isn't a math website.

On discord, it doesn't show steam specifically, but if you're playing a game THROUGH steam then yes, it will show.

To hide this, go to options -> game activity -> and disable "Display currently running game as a status message" on discord.

If you want to hide your status on steam, just put your status to invisible :)

Need help solving this for two points for a graph...3x+3=0​
coldgirl [10]

3x + 3 = 0 //Subtract -3 on both sides

3x = -3 //Divide 3 on both sides

x = -1

Here x = -1 and y is all the values where x = -1, so basically from negative infinity to infinity.

Make sure when writing the solution, y is any value and x stays the same.

Solution: (-1,0) and (-1,1)

//Hope this helps
