I realy need help please!!!!

1-Describe the translation in words: (x, y) (x - 4, y - 9)
A)4 units to the left, 9 units down
B)4 units to the left, 9 units up
C)4 units to the right, 9 units down
D)4 units to the right, 9 units up

2-][3-,2.[1,4],[-5,4]2,-3]at element is in row 2 and column 1 of the resulting matrix?
(A)3
(B)1
(C)-1
(D)7
3- Triangle SRT has vertices S(1, 2), R(0, ¨C3), and T(¨C4, 3). If triangle SRT is centered at (0, 0) and dilated using a scale factor of 2, what are the coordinates of S¡ä , R¡ä , and T¡ä ?

A: S¡ä (1, 4), R¡ä (0, ¨C6), T¡ä (¨C4, 6)
B: S¡ä (2, 2), R¡ä (0, ¨C3), T¡ä (¨C8, 3)
C: S¡ä (2, 4), R¡ä (0, ¨C6), T¡ä (¨C8, 6)
D:S¡ä (3, 4), R¡ä (2, ¨C1), T¡ä (¨C2, 5)

help please...

Thanks

13 units down

1- To describe the translation in words, we can compare the coordinates of the original point (x, y) to the new coordinates (x - 4, y - 9).

In this case, the x-coordinate is being shifted 4 units to the left (since we subtract 4 from x). Additionally, the y-coordinate is being shifted 9 units down (since we subtract 9 from y).

Therefore, the correct description of the translation in words would be A) 4 units to the left, 9 units down.

2- To find the element in row 2 and column 1 of the resulting matrix, we can refer to the given matrix representation: [3, -2; 1, 4; -5, 4; 2, -3].

In this matrix, we count rows from top to bottom and columns from left to right. So, for row 2 and column 1, we look at the second row and the first column.

The element in this position is 1.

Therefore, the correct answer is B) 1.

3- To find the coordinates of Sä, Rä, and Tä after centering and dilating the triangle SRT, we need to apply the transformations step by step.

First, to center the triangle at (0, 0), we need to subtract the x-coordinate of the center from each vertex's x-coordinate, and subtract the y-coordinate of the center from each vertex's y-coordinate.

So, after centering, the coordinates become: Sä (1-0, 2-0), Rä (0-0, -3-0), and Tä (-4-0, 3-0), which simplifies to Sä (1, 2), Rä (0, -3), and Tä (-4, 3).

Next, to dilate the triangle using a scale factor of 2, we multiply each coordinate by the scale factor.

So, after dilation, the coordinates become: Sä (1 * 2, 2 * 2), Rä (0 * 2, -3 * 2), and Tä (-4 * 2, 3 * 2), which simplifies to Sä (2, 4), Rä (0, -6), and Tä (-8, 6).

Therefore, the correct answer is C) Sä (2, 4), Rä (0, -6), and Tä (-8, 6).
