The ordered pair (-1,5) is a solution to the system because it makes both equations true.
1) x+y=4
2) x-y=-6
1) -1 + 5 = 4
5-1 = 4 you can switch the order to make it easier to understand
so
4 = 4
2) -1 - 5 = -6
-1 + -5 = -6 you can change the sign in the middle and make y -
so
-6 = -6
Answer: 10 units
Step-by-step explanation:
Use the distance formula(√(x1-x2)^2+(y2-y1)^2)

Thus, the radius of the circle is 5. Because the diameter is 2r, the diameter = 2(5) = 10

The area of a 2D form is the amount of space within its perimeter. The area of the bottom of the box is 64 square inches.
<h3>What is an area?</h3>
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or other quadrilateral, multiply its length by its width.
Given the radius of the base of the plastic bottle is 2 inches, and there are four bottles arranged as shown below, therefore, the area of the bottom of the box is,

Hence, the area of the bottom of the box is 64 square inches.
