In this attached picture, we can prove that triangles AOB and COD are congruent. ∠CDO and ∠ABO are equal because they are alternate angles. Similarly, ∠OAB and ∠OCD are equal because they are alternate angles, as well. We have a rectangle and in the rectangle, opposite sides are equal; AB = CD. Then, because of Angle-SIde-Angle principle, we can say that triangles AOB and COD are equal. If triangles are congruent, then OD = OB and OC = AO. Applying congruency to the triangles ACD and BCD, we can see that these triangles are also congruent. It means that the diagonals are equal. Since, OD = OB and OC = AO, it proves that the point O simultaneously is the midpoint and intersection point for the diagonals.
For this case we have the following vertices:
D = (- 1, -1)
E = (1, -1)
F = (- 1, -6)
Then, the vertices after the transformation are:
D '= (- 1, 1)
E '= (1,1)
F '= (- 1,6)
The x coordinate remains the same
The y coordinate change sign.
Therefore, the transformation is:
Reflection on the x axis.
Answer:
Reflection on the x axis.
option 1
Answer:
y = -1/2x - 2
Step-by-step explanation:
The line is negative, so the slope has to be negative. (-1/2)
You would use the equation to find the first point to plot. -1/2 times 0 is 0. 0-2 equals -2. This means that the first point would be (0,-2). This proves that the correct equation is <u><em>y = -1/2x - 2</em></u>.
Do 19 x 6 x 2 = 228
then 28 x 19 x 2 = 1064
then 28 x 6 x 2 = 336
<span>then do 228 + 1064 + 336 = 1628</span>
Answer:
i would say d.
Step-by-step explanation:
because depending on whether he is a competitor seller go's by the competition prices they might want to know how low is his cheapest shirt they might want to know which one is cheaper, and he would also keep track of his sales
