What set of reflections would carry triangle ABC onto itself? triangle ABC on the coordinate plane with point A at 1, 2, point B at 2, 4, and point C at 3, 0.
Answers
The A y-axis , B y-axis and C would also be reflected over the Y-axis. When you think about the coordinates on a graph, and with that also being said there all positive.
Answer:
y-axis, x-axis , y-axis and x-axis
Step-by-step explanation:
Given : In triangle ABC
The coordinates are
A = (1,2) , B=(2,4) and C =(3,0)
Rule of reflection:
*Reflecting a point (x, y) across the y-axis will map it to (-x, y).
*Reflecting a point (x, y) across the x-axis will map it to (x, -y).
If you do a reflection on coordinate point A = (1,2) across y-axis we get
then, reflecting a point (-1 , 2) across x -axis we get, (-1, -2)
then, reflecting a point (-1 , -2) across y-axis we get, (1 , -2)
and
reflecting a point (1, -2) across x- axis we get the result same i.e, A =(1,2)
Similarly,
For B = (2,4) across y-axis (-2, 4) across x- axis
(-2, -4) across y -axis
(2 , -4) across x axis
( 2, 4) = B
for C = (3, 0) across y-axis (-3, 0) across x- axis
(-3, 0) across y -axis
(3 , 0) across x axis
(3, 0) = C
Therefore, the set of reflection would carry triangle ABC onto itself is:
y-axis, x-axis , y-axis and x-axis

Answers
n = $0.05
d = $0.1
0.05n + 0.1d = 5.20
0.05n = 6 (0.1d) ; n = 0.083d
Then we will solve it by substitution:
0.05(0.083d) + 0.1d = 5.20
0.42d + 0.1d = 5.20
0.52d = 5.20
d = 10
n = 0.083(10)
n = 0.83

What is a Polynomial?
Polynomial, a mathematical expression made comprised of numbers and variables arranged in specific patterns.
As per the given data:
We are given a table where in each row and each column an expression is written, we have to fill the table correspondingly after finding out the product of each row head and column head
For row with d and column with 2d²:
= d × 2d² = 3d³
For row with d and column with 11d:
= d × 11d = 11d²
For row with d and column with -4:
= d × -4 = -4d
For row with -9 and column with 2d²:
= -9 × 2d² = -18d²
For row with -9 and column with 11d:
= -9 × 11d = -99d
For row with -9 and column with -4:
= -9 × -4 = 36
The tables should be filled in the following order:
3d³ 11d² -4d
-18d² -99d 36
Hence, The table should be filled in the following order:
3d³ 11d² -4d
-18d² -99d 36
