John didn't check his work.

The appropriate transformation rule is (x -4, y-7).

<u>Sample Response:</u> The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5) into the rule. You get (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image. Instead the rule was applied to the image. This is the source of the error.

List a positive and negative number whose absolute value is greater than 3?​
Georgia [21]

Answer: |5|, |-6|, |4|, |-3.5|

Step-by-step explanation: The absolute value is related with the distance between the number and the zero of the number line, then each number greater than 3 will have an absolute value greater than 3, as we can see in the picture, the numbers positive or negative will have a positive distance to the origin of the number line.

I need help with this please!! ​
vovangra [49]

Answer:

{6x}^{3}  +  {9x}^{2}  - 18x + 3

Step-by-step explanation:

1. Expand by distributing sum groups.3x( {2x}^{2}  + 5x - 1) - 3( {2x}^{2}  + 5x - 1)

2. Expand by distributing terms.

{6x}^{3}  +  {15x}^{2}  - 3x - 3( {2x}^{2}  + 5x - 1)

3.Expand by distributing terms.

{6x}^{3}  +  {15x}^{2}  - 3x - ( {6x}^{2}  +  15x - 3)

4. Remove parentheses.

{6x}^{3}  +  {15x}^{2}  - 3x -  {6x}^{2}  - 15x + 3

5. Collect like terms.

{6x}^{3}  +  {15x}^{2}  -  {6x}^{2} ) + ( - 3x - 15x) + 3

6. Simplify.

{6x}^{3}  +  {9x}^{2}  - 18x + 3

Thus. the answer is,

{6x}^{3}  +  {9x}^{2}  - 18x + 3
