A teacher bought 7 packs of dominoes for a math game. Each pack had 55 dominoes. The teacher already had 118 dominoes to use in
Mamont248 [21]

Answer:

the teacher had 503 dominoes for the game.

Step-by-step explanation:

In order to find the answer, first you have to find the amount of dominoes the teacher purchased by multiplying the number of packs for the number of dominoes in each pack:

7*55=385

Now, since the stament indicates that the teacher already had 118 dominoes to use in the game, you have to add this amount to the number of dominoes that were purchased:

385+118=503

According to this, the answer is that the teacher had 503 dominoes for the game.

22 Points!! I NEED Help ASAP plz!!!!
Schach [20]

Answer:

The correct option is B.

Step-by-step explanation:

The vertices of preimage are L(2,-2), M(4,-2), N(1,-3) and O(5,-3).

The vertices of image are L'(-3,-2), M'(-3,-4), N'(-4,-1) and O'(-4,-5).

The relationship between preimage and image is defined as

(x,y)\rightarrow (y-1,-x)

In option A, 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left.

If a figure rotated 90-degree counterclockwise, then

(x,y)\rightarrow (-y,-x)

Translation 1 unit to the left,

(x,y)\rightarrow (-y-1,-x)

Therefore option A is incorrect.

In option B, 270-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left.

(x,y)\rightarrow (y-1,-x)

Therefore option B is correct.

In option C,  a translation 1 unit to the left followed by a 270-degree counterclockwise rotation about the origin.

(x,y)\rightarrow (y,-(x-1))

Therefore option C is incorrect.

In option D, a translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin.

(x,y)\rightarrow (-y,x-1)

Therefore option D is incorrect.
