If triangle ABC is rotated 180 degrees, reflected over the y-axis, and reflected over the X-axis, where will point A' lie?
O (5, -4)
O(4,-5)
O(-4,5)
O-5,4)
Point A lies on (5, -4).
Given that,
If triangle ABC is rotated 180 degrees, reflected over the y-axis, and reflected over the X-axis,
We have to determine,
Where will point A lie?
According to the question,
When rotating a figure of 180 degrees about the origin either in the clockwise or counterclockwise direction, each point of the given figure has to be changed from (x, y) to (-x, -y) and graph the rotated figure.
Then, the points after rotation are (-5, -4).
When the reflection about the y-axis, (5,4) becomes (-5, 4).
Reflect again about the x-axis, (-5, 4) becomes (5,-4).
Hence, point A lies on (5, -4).

The coordinates of the midpoint of $\overline{GH}$ are $M\left(8,\ 0\right)$ and the coordinates of one endpoint are $H\left(-2,\ 9\right)$ .
The coordinates of the other endpoint are
Answer:
Step-by-step explanation:
G(18,-9)
The coordinates of the midpoint of GH are M (8,0) and the coordinates of one endpoint are H(-2, 9). We need to find the coordinates of G. Let G is (x,y).It can be done using mid point formula i.e.
So,
The coordinate of the other endpoint are G (18, -9).
Here, the coordinate of the midpoint of GH are M (8, 0) and coordinate of one endpoint are H (-2, 9)
We have to find the coordinate of G.
What is midpoint of a line?
Measure the distance between the two end points, and divide the result by 2, then we find the value of midpoint of a line.
Now,
Let coordinate of G is (x, y).
The coordinate of the midpoint of GH are M (8, 0) and coordinate of one endpoint are H (-2, 9).
[tex]\frac{x+(-2)}{2} =8\\x-2=16\\x=18[/tex]
And,
[tex]\frac{y+9}{2} = 0\\y=-9[/tex]
Hence, The coordinate of the other endpoint are G (18, -9).

7) Write an equation for the tile pattern and use it to find out how many tiles will there be in figure 32?
9514 1404 393
Answer:
98
Step-by-step explanation:
The numbers of tiles are 5, 8, 11. This is an arithmetic sequence with a first term of 5 and a common difference of 3. The n-th term is ...
an = a1 +d(n -1) . . . . . for first term a1 and common difference d
This sequence has n-th term ...
an = 5 +3(n -1)
Then the 32nd term is ...
a32 = 5 + 3(32 -1) = 5 +93 = 98
Figure 32 will have 98 tiles in it.
