Answer:

The graph of the triangle LMN and the image L'M'N' created by rotation of ΔLMN through 180° made  with MS Excel is attached

The transformation involved in the 180° rotation of ΔLMN to create ΔL'M'N' includes;

The changing of the signs of the <em>x</em> and y-values of the coordinates of the vertices ΔLMN to get the corresponding <em>x</em> and y-values of the coordinates of the vertices of ΔL'M'N' as follows;

Before, rotation

The coordinates of the vertices of ΔLMN are; L(3, 3), M(9, 9), and N(9, 3)

After 180° rotation

The coordinates of the vertices of the image of ΔLMN, which is ΔL'M'N' are; L'(-3, -3), M'(-9, -9), and N'(-9, -3)

Therefore, the image of ΔLMN, ΔL'M'N' is located in the third quadrant, while the preimage ΔLMN is in the first quadrant

Part B

The lines drawn through L and L' and through M and M' are colinear lines

Part C

The lines dawn through points N and N' will not pass through the same line as the lines through L and L' and through M and M', because the three points are not colinear

Step-by-step explanation:

Find the perimeter of triangle ABC.
Harlamova29_29 [7]
By definition, the perimeter of the triangle is the sum of its sides.
 We must then use the formula of distance between points:
 d =  \sqrt{(x2-x1) ^ 2 + (y2-y1) ^ 2}
 We now look for the longitus for each of the sides:
 
 For L1:
 L1 = \sqrt{(6-2)^2 + (6-2)^2}
 L1 =  \sqrt{32} &#10;
 L1 = 4\sqrt{2}

 For L2:
 L2 = \sqrt{(7-2)^2 + (-3-2)^2}
 L2 = \sqrt{50}
 L2 = 5\sqrt{2}

 For L3:
 L3 = \sqrt{(7-6)^2 + (-3-6)^2}
 L3 = \sqrt{82}
 
 Then, the perimeter is given by:
 P = L1 + L2 + L3
 Substituting values we have:
 P = 4\sqrt{2} + 5\sqrt{2} + \sqrt{82} &#10;&#10;P = 9\sqrt{2} + \sqrt{82}

 Answer:
 
the perimeter of triangle ABC is:

Equations of Lines help!
Vedmedyk [2.9K]
The answer is D. Note that the y-intercept is -3, not 3. So, when x is at 0, y should be -3. Choice D is the only graph with a y-intercept of -3.
