The midpoint of AB is M(-3, 0). If the coordinates of A are (1,-4), what are the coordinates of B?

zimovet [89]

Using the given information, the coordinates of B are (-7, 4)

<h3>Midpoint of a Line </h3>

From the question, we are to determine the coordinates of B.

Given a line with endpoints (x₁, y₁) and (x₂, y₂), then the midpoint of the line is

((x₁+x₂)/2, (y₁+y₂)/2)

From the given information,

The midpoint of AB is M(-3, 0)

and

The coordinates of A are (1,-4)

Let the coordinates of B be (x₁, y₁)

Then,

-3 = (1 + x₁)/2

-6 = 1 + x₁

x₁ = -6 -1

x₁ = -7

Also,

0 = (-4 + y₁)/2

0 = -4 + y₁

y₁ = 0 + 4

y₁ = 4

Hence, the coordinates of B are (-7, 4)

Chase made a scale drawing of a neighborhood park. The scale of the drawing was 1 millimeter : 8 meters. The volleyball court is

AlexFokin [52]

Answer:

Length of the volleyball court in drawing = 2 mm

Step-by-step explanation:

8 meter = 8 *1000 = 8000 mm

Scale factor = 1 : 8000

Length of the volleyball court in drawing = x

1 : 8000 :: x : 16000

$\dfrac{1}{8000}=\dfrac{x}{16000}\\\\\\\dfrac{1}{8000}*16000=x\\\\$

x = 2 mm
