You have that A = (9,2), B = (4,-4)
In order to find the coordinates of C, a point at the middle of the segment AC, you calculate the midpoint of each couple of coordinates.
For the first coordinate:
For the second coordinate:
Hence, the coordinate of C is C = (6.5 , -1)
For the case of the points (4a,5g) and (-6a,-g), you have:
Hence, the midpoint is (-a,2g)
Answer:
15
Step-by-step explanation:
First add 20 to both sides to get x/3 = 5
Then multiply both sides by 3 to get 15.
You can check it by substituting it into the equation
15/3 - 20 = -15
5 - 20 = -15
-15 = -15
Answer:
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
The perimeter will also be halved: (1/2)(20) = 10.
Example: a rectangle of length 14 ft and width 8 ft has perimeter P = 2(14 ft) + 2(8 ft), or 28 ft + 16 ft = 44 ft.
If we halve the length and width, we get 7 ft and 4 ft, and the P is
2(7 ft) + 2(4 ft) = 14 ft + 8 ft = 22 ft, which is half of the original perimeter 44.
