In 20 and 21, use the coordinate plane du -
The graph shows the locations of point G and point H.
Point J is graphed at (n, -3). The distance from point H
to point J is equal to the distance from point H to point G.
21. What is the value of n?

sussy

Step-by-step explanation:

I am so sorry-

The distance from point H to point J is 3 units.The value of n is 3.

Step-by-step explanation:

From the graph, point H is at (n,-6)

Point G location will be at (0,-6)

Point J is at (n,-3)

Observing point H(n,-6) and point J (n,-3) you notice that point J is above point H.find how much far is point H from point J.

d= √(x₂-x₁)²+(y₂-y₁)²

d=√(-3--6)²

d=√3² =√9 = 3

Distance H to J is 3 units

Point G (0,-6) and point H (n,-6) have a distance of 3 units same as point H to J

To get the horizontal length will ;

d=√ (n-0)²

d=√n² but d=3 units

3=√n²

9=n²

√9=n

3=n

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
