Given the following coordinates complete the glide reflection transformation.

Romashka [77]

Answer:

$A" = (7,-2)$

$B" = (10,0)$

$C"= (12,-3)$

Step-by-step explanation:

Given

$A = (4,2)$

$B = (7,0)$

$C =(9,3)$

a: Reflect over x-axis

The rule of this is:

$(x,y) \to (x,-y)$

So, we have:

$A' = (4,-2)$

$B' = (7,0)$

$C' = (9,-3)$

b: Shift 3 units left

The rule of this is:

$(x,y) \to (x+3,y)$

So, we have:

$A" = (4+3,-2)$

$A" = (7,-2)$

$B" = (7+3,0)$

$B" = (10,0)$

$C"= (9+3,-3)$

$C"= (12,-3)$

Name the integer

Ivenika [448]

Answer:

1. Gained 9 kilos = $+9$

2. 32 steps backward = $-32$

3. Decreased by P5 = $-P5$

Step-by-step explanation:

Natural numbers refer to numbers that are used for counting.

Whole numbers include 0 and natural numbers.

An integer is a collection of whole numbers and their negatives.

1. Gained 9 kilos = $+9$

(Gained is denoted by + )

2. 32 steps backward = $-32$

(backward is denoted by - )

3. Decreased by P5 = $-P5$

(decrease is denoted by - )

Ariana has 2/3 quart of milk. She uses 3/4 of it in a cookie recipe. How much milk did Ariana us in her recipe

Mamont248 [21]

If Ariana has 2/3 quart of milk and she uses 3/4 of it then the problem would be:
2/3 x 3/4 = 6/12 or 1/2
So she would have 1/2 quart

Annabelle arranged her 42 building blocks into 3 rows of 14 blocks. Then, she rearranged them into 6 rows of 7 blocks. What two

cupoosta [38]

Answer:

21 rows 2 blocks

1 row 42 blocks

Step-by-step explanation:

Given that:

Number of blocks with Annabelle = 42

First arrangement = 3 rows 14 blocks

Second arrangement = 6 rows 7 blocks

To find:

The other two factor pairs that could be used to rearrange the blocks again?

Solution:

Here, we will have to find the factor pairs of total number of blocks present with Annabelle.

i.e. 42

First of all, let us have a look at the factor pairs of 42.

$42 = 3\times 14\\42 = 6\times 7\\42 = \underline{2\times 21}\\42 = \underline{1\times 42}$

Therefore, the other two factor pairs can be 2, 21 and 1, 42.

The other two possible factor pairs are:

21 rows 2 blocks

1 row 42 blocks
