  11.7

Step-by-step explanation:

GeoGebra can not only draw the picture, it can answer the question. The approximate distance between the points is about 11.7 units.

__

The distance formula is used for this:

  d = √((x1 -x1)² +(y2 -y1)²)

  d = √((-4-2)² +(-3-7)²) = √(36 +100)

  d = √136 ≈ 11.7

_____

Once you find that the distance is about √136, you know it is more than 11 (11² = 121) and less than 12 (12² = 144). The only answer choice that makes any sense is 11.7.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
