Answer:

see below

Step-by-step explanation:

The points at the corners of the given figure are ...

(0, 0), (0, 4), (3, 4), (3, 0)

When the figure is scaled by a factor of 1/3, each of the coordinates is multiplied by 1/3:

(0, 0), (0, 4/3), (1, 4/3), (1, 0) . . . . . points scaled by 1/3

When the figure is scaled by a factor of 3/2, each of the coordinates is multiplied by 3/2:

(0, 0), (0, 6), (9/2, 6), (9/2, 0) . . . . . . points scaled by 3/2

The points that are on your list are shown in bold above.

Answer:

see below

Step-by-step explanation:

The rotation transformations are ...

90° : (x, y) ⇒ (-y, x)

180° : (x, y) ⇒ (-x, -y)

270° : (x, y) ⇒ (y, -x)

Applying these to the given points, you get ...

9) A'(6, 9)

10) A'(15, 11)

11) A'(9, 6)

12) A'(-11, 15)

13) A'(6, -9)

14) A'(15, -11)

This is geometry can someone help me?

Answer: JG= 12.
Explantation: Since it is a parallelogram, we know that EJ and JG are congruent (equal). Therefore, we set EJ and JG as an inequality. (3w = w + 8) We solve for W and get w=4. Plug in 4 into the JG equation (4 + 8). The answer would be 12.

How many solutions does the following system of equations have y=5/2x+2 2y=5x+8

irakobra [83]

Answer:

No solutions.

Step-by-step explanation:

If you normalize the second one by dividing by 2, you get:

y = 5/2x+4.

Now you see that both have the same slope (5/2). They are parallel lines that never intersect.
