Find the coordinates of H if X(-8, 4) is the midpoint of GH and G(2, -9).

skelet666 [1.2K]

Step-by-step explanation:

Hey there!

The given midpoint is; X(-8,4) and G(2,-9).

To find: H

Now; You need to use formula for midpoint.

$midpoint(x) = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

Put all values.

$( - 8,4) = (\frac{ 2 + x}{2} , \frac{ - 9 + y}{2} )$

As they are equal, their corresponding elements are equal.

$- 8 = \frac{2 + x}{2}$

$- 16 - 2 = x$

x = -18

$4 = \frac{ - 9 + y}{2}$

$4 \times 2 = - 9 + y$

$8 + 9 = y$

$y = 17$

Therefore, y = 17.

Therefore, H =( -18,17).

Hope it helps....

This a problem of conversion of units. to convert units, you must know at what values are each units equal. for this problem we must convert miles to feet. so 1 mile is equivalent to 5280 ft. so the answer is :
length in feet = 0.6 miles ( 5280 ft / 1 mile)
length in feet = 3168 feet

PLEASE HELP ILL GIVE BRAINLIEST!

Answer:

10 sides (decagon)

Step-by-step explanation:

You find the perimeter by adding up all the sides of a shape.

side + side + side + side... = perimeter

You know that each side is 4/5 centimeters. You also know that the perimeter is 8 centimeters.

You can set up an equation like this:

4/5 * number of sides = 8

or you can write it in a simpler form as:

4/5x=8

Now solve it like a normal equation:

5 * (4/5x) = (8) * 5

(4x) / 4=(40) / 4

x = 10

So, you know the shape has 10 sides that are 4/5 centimeters each.
