Answer:
D. For a ratio of 3:2, divide AB into 5 equal parts. Each equal part is 2 units, so the point that divides AB into a 3:2 ratio is 2.
Step-by-step explanation:
The complete question is:
<em>Point A is at –4 and point B is at 6. Which describes one way to find the point that divides AB into a 3:2 ratio? </em>
- In a 3:2 ratio there are 3 + 2 = 5 equal parts.
- The distance between points A and B is: 6 - (-4) = 6 + 4 = 10 units.
- Each equal part is 10/5 = 2 units.
- Point 2 is at 2 - (-4) = 6 units from -4
- Point 2 is at 6 - 2 = 4 units from 6
- Ratio 6:4 is equivalent to ratio 3:2
Answer:
Step-by-step explanation:
The diagonals of a parallelogram bisect each other.
This means that:
Add x to both sides:
Divide both be sides by 3
Therefore the value of x is
Answer:
x² + y² +10x -6y - 69 = 0
Step-by-step explanation:
We need to write the standard equation of circle with , centre (-5,3) and radius 10 unit . The Standard equation of the circle ⭕ is ,
=> ( x - (-5))² + (y -3)² = r²
=> ( x +5)² + (y-3)² = 10²
=> x² + 25 + 10x + y² +9-6y = 100
=> x² + y² +10x -6y + 31 = 100
=> x² + y² +10x -6y - 69 = 0
<h3>• Hence the equation of the circle is x² + y² +10x -6y - 69 = 0.</h3>
