Remark
You are using the midpoint formula. Instead of finding the midpoint, you are looking for one of the points, so you have to rearrange the formula a little bit.
Givens
Midpoint (4,2)
One endpoint (6,1)
Object
Find the other endpoint.
Formula
m(x,y) = (x1 + x2)/2, (y1 + y2)/2)
Solution
Find the x value
4 = (6 + x2)/2 Multiply both sides by 2
4*2 = 6 + x2 Subtract 6 from both sides.
8 - 6 = x2
x2 = 2
Find the y value
2 = (1 + y2)/2 Multiply by 2
4 = 1 + y2 Subtract 1 from both sides.
4 - 1 = y2
y2 = 3
Conclusion
R(x,y) = (2,3)
Answer: Length = 28cm
Width = 7cm
Step-by-step explanation:
Let the width be represented by x.
Since the length is four times its width. Therefore, the length would be:
= 4 × x = 4x
The perimeter of a rectangle is calculated as:
= 2(length + breadth)
Therefore, 2(4x + x) = 70
2(5x) = 70
10x = 70
x = 70/10
x = 7
Therefore, width = 7cm
Length = 4x = 4 × 7 = 28cm
Answer:
Step-by-step explanation:
start at y intercept +5. Go up 3 points then go to the right 8 points and keep on doing that. Formula for slope rise/run. Rise is 3. Run is 8. Then connect the line.
Answer: K,S,G,D,B
because KG + GD = KD => G is between K and D
SD + DB = SB => D is between S and B
KS + SG = KG => S is between K and G
=> The order of the points from left to right is K,S,G,D,B
