how do you explain the midpoint of cd is e (-1,0). one endpoint is c(5,2). what are the coordinates of the other endpoint?
Answers
The other endpoint will be equal to (-7, -2).
What is coordinate geometry?
A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that the midpoint of cd is e ( -1,0 ) one endpoint is c( 5,2 ). The midpoint will be calculated as:-
Midpoint = (x₁+x₂ / 2 , y₁+y₂ / 2)
5 + x₂ / 2 = -1
5 + x₂ = -2
x2 = -7
2 + y₂ / 2 = 0
2 + y₂ = 0
y₂ = -2
Therefore, the other endpoint will be equal to (-7, -2).
To know more about coordinate geometry follow

5 + x2 / 2 = -1
5 + x2 = -2
x2 = -7
2 + y2 / 2 = 0
2 + y2 = 0
y2 = -2
Other endpoint: (-7, -2)

Step-by-step explanation:
Slope intercept form is
We know that the -24 is b, and the 3 before the x is the m (slope).
So what you have to do is remove the -24 from the left side of the equation, to keep the y alone. To do that, add 24 to both sides of the equation.
-4y -24 +24 = 3x + 24
-4y = 3x + 24
Now, we need to get rid of the -4 from the y, so the y is alone. To do that, divide both sides by -4.
-4y ÷ -4 = (3x÷-4) + (24÷-4)

8x^3 - 125 = (2x - 5) * (jx^2 + kx + 25)
8x^3 - 125 = 2jx^3 + 2kx^2 + 50x - 5jx^2 - 5kx - 125
8x^3 = 2jx^3
4x^3 = jx^3
j = 4
2kx^2 + 50x - 5jx^2 - 5kx = 0
2kx^2 + 50x - 20x^2 - 5kx = 0
2kx^2 - 20x^2 + 50x - 5kx = 0
2kx - 20x + 50 - 5k = 0
2x(k - 10) = 5k - 50
2x(k - 10) = 5(k - 10)
k = 10
The correct result would be: j = 4 and k = 10.

Answer:
x=14
y=30
Step-by-step explanation:
5x+25=3x+53
5x=3x+28
2x=28
x=14
2y+35=95
2y=60
y=30
(I assumed all of the angles are equal, correct me if I'm wrong.)
Answer:x=14
Step-by-step explanation:
Let's first understand what we need to do. We need to solve for two variables, x and y. We do these by setting two systems of equations equal to each other. This is easily done for x, but for y the other equation is missing. Keep this in mind for later.
So, we will first start off by solving for x. We do this by using inverse operations.
5x+25=3x+53 We will subtract
5x=3x+28
2x=28 Divide
x=14
You can plug 14 into both the xs and they will be similar, and both will have the similar results once you solve for y and plug it into the equation along with x.
We know that the 5x+25 on the left is adjacent to 2y+35, and so is the second x. Adjacent angles add up to 180 total, and so to solve for y we need to plug 12 in the first x.
5(14)+25=95
180-95=85
85 is the value of 2y+35
We will solve for y just like any other alegrbaic problem
85=2y+35
50=2y
y=25
We know know that y is 25 and x is 14
Plug both values into 2 adjacent angles and they will add up to 180.
