Answer is A hope i helped
(-2) + 6 + 1 = 1 + 6 + (-2)
-2 + 7 = 7 - 2
5 = 5

Answer: (1,3)</h3>
=====================================================
Explanation:
Note that the two shaded regions overlap to form the darker shaded region. The point (1,1) is only in the green region, but not in the blue region. It needs to be in both regions for it to be a solution to the system. In contrast, the point (1,3) is on the boundary of the blue region and in the green region as well. It's a solution point because of this.
Points on the boundary are included because of the "or equal to" as part of the inequality sign. Hence the solid boundary lines rather than dashed boundary lines.
The solution (1,3) means that x = 1 and y = 3 pair up together. It says that Cody can buy x = 1 hotdog and y = 3 packs of peanuts so that he has at least 4 snacks, and he stays within the $7 budget.
Going back to (x,y) = (1,1) for a moment, this isn't a solution because x+y = 1+1 = 2 is not 4 or larger. In other words, he only buys 2 snacks here instead of 4 or more.
Answer:
distance formula= 
= find the length(units) using coordinates.
slope formula= 
= determines slope of a line using two points on the line(coordinates)
When working with polygons the main properties which are important are:
The number of sides of the shape.
The angles between the sides of the shape.
The length of the sides of the shape.
length , width
straight lines , angles, vertices, vertex
A polygon is any 2-dimensional shape formed with straight lines.
a plane figure with at least three straight sides and angles, and typically five or more.
Step-by-step explanation:
<h2><u>
answer= use distance and slope to determine that opposite side of a polygon are the same length and same slope</u></h2>
