When we subtract equations we subtract the left sides, subtract the right sides, and set them equal.  I'll show detailed steps but usually you can just do it all in one step.

5x + 4y = 25

5x + 2y = 3

Subtracting,

5x + 4y -(5x + 2y) = 25 - 3

2y = 22

The problem is easily solved from here, but let's call it done with

Choice B

Jaycee draws a sequence of squares on the coordinate plane. First she draws a square in the center with corners at 2,2 spots and
Anon25 [30]

This is based on understanding what dilation means in a graph transformation.

<em />

<em>The dilation from first square directly to sixth square will be; (x,y) -> (243, 243)</em>

<em />

  • In transformations, dilation of an object involves producing an image of the object that is the same shape but not the same size.

This means that if we want to dilate a square, we will produce a bigger square of a different size.

  • We are told one corner of the first square she drew is (2, 2). This means that one side of the square is 2 units as the four sides of a square are equal.

  • For the second square, she dilates the first one using (x, y) -> (3x, 3y).

This means the corner that was (2, 2) will now be (3 × 2), (3 × 2) = (6, 6)

  • For the third square, it will be; (3 × 6), (3 × 6) = (18, 18)

  • For the fourth square, it will be; (3 × 18), (3 × 18) = (54, 54)

  • For the fifth square, it will be; (3 × 54), (3 × 54) = (162, 162)

  • For the sixth square, it will be; (3 × 162), (3 × 162) = (486, 486)

Since first square was (2, 2), then it means dilation from first square directly to sixth square will be; (x,y) -> (486/2, 486/2)

⇒ (x,y) -> (243, 243)
