The coordinates of the point that is one-half the distance between A(-1,-2) and B(6,12) is (2.5,5)
What is the midpoint?
The mid-point lies midway between the two ends. Its x value lies in the middle of the other two x values. Its y value lies in the middle of the other two y values.
Given, ![A(6,12) = (x_{1}, y_{1} )](https://tex.z-dn.net/?f=A%286%2C12%29%20%3D%20%28x_%7B1%7D%2C%20y_%7B1%7D%20%29)
![B(6,12) = (x_{2}, y_{2} )](https://tex.z-dn.net/?f=B%286%2C12%29%20%3D%20%28x_%7B2%7D%2C%20y_%7B2%7D%20%29)
Let M is a midpoint of AB, then
![M(x,y)=(\frac{x_{1}+x_{2} }{2} ,\frac{y_{1} +y_{2}}{2} )= (\frac{-1+6}{2} ,\frac{-2+12}{2} )=(2.5,5)](https://tex.z-dn.net/?f=M%28x%2Cy%29%3D%28%5Cfrac%7Bx_%7B1%7D%2Bx_%7B2%7D%20%20%7D%7B2%7D%20%2C%5Cfrac%7By_%7B1%7D%20%2By_%7B2%7D%7D%7B2%7D%20%29%3D%20%28%5Cfrac%7B-1%2B6%7D%7B2%7D%20%2C%5Cfrac%7B-2%2B12%7D%7B2%7D%20%29%3D%282.5%2C5%29)
The midpoint of point AB is M(2.5,5)
Therefore, the coordinates of the point which is one-half the distance between A(-1,-2) and B(6,12) is M(2.5,5).

Step-by-step explanation:
Hi there!
![\large\boxed{\text{ 10.5 in}^3}}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%5Ctext%7B%2010.5%20in%7D%5E3%7D%7D)
Begin by solving for the area of the base:
A = 1/2 (bh)
Thus:
A = 1/2(2 · 1.5) = 1.5 in²
Multiply by the depth to find the volume:
A = 1.5 × 7 = 10.5 in³
Answer:
The value of x is 21.
Step-by-step explanation:
Since this is a right angle triangle, you can apply Pythagoras theorem, side² + side² = hypo² :
(x + 3)² + 10² = (x + 5)²
x² + 6x + 9 + 100 = x² + 10x + 25
x² + 6x + 109 - x² - 10x - 25 = 0
-4x + 84 = 0
-4x = -84
4x = 84
x = 84 ÷ 4
x = 21 units
First, let's add 30 to both sides:
4x - 30 +30 ≥ -3x + 12+30
4x ≥ -3x + 42
Now, let's add 3x to both sides
4x +3x ≥ -3x+3x + 42
7x ≥ 42
Let's divide both by 7:
x ≥ 6
