I need help with this question.

Mathematics

Papessa [141]3 years ago

Answer:

It's A, c =2.5d

Step-by-step explanation:

When it comes to problems like this, I usually look through the answers and try to plug in the numbers until I get the right equation that fits with the graph.

2.5(5) = 12.5

2.5(10)= 25

2.5(15)= 37.5

2.5(20) = 50

2.5(25) = 62.5

If you compare this to the graph, you'll notice the solutions are the same as the Total Cost (c). That's because c= 2.5d is the right equation for this graph. (Sorry if my explanation is confusing)

HELP PLEASE! Square T was translated by the rule (x + 2, y + 2) and then dilated from the origin by a scale factor of 3 to creat
Sveta_85 [38]

The statement that explains why the squares are similar is

Option C. Translations and dilations preserve betweenness of points; therefore, the corresponding sides of squares T and T″ are proportional.

<h3>Further explanation</h3>

<em>There are several types of transformations:</em>

  1. <em>Translation</em>
  2. <em>Reflection</em>
  3. <em>Rotation</em>
  4. <em>Dilation</em>

Let us now tackle the problem!

\texttt{ }

This problem is about Translation and Dilation.

<em>Properties of </em><em>Translation</em><em> of the images compared to pre-images:</em>

  • preserve Side Length
  • preserve Orientation
  • preserve Collinearity
  • preserve Betweenness of Points

\texttt{ }

<em>Properties of </em><em>Dilation</em><em> of the images compared to pre-images:</em>

  • not preserve Side Length
  • not preserve Orientation
  • preserve Collinearity
  • preserve Betweenness of Points

\texttt{ }

From the information above, we can conclude that:

Option A is not true because Dilations do not preserve side length.

Option B is not true because Dilations do not preserve orientation.

Option C is true because Translations and Dilations preserve betweenness of points.

Option D is not true. Although Translation and Dilations preserve collinearity but it cannot be related to the corresponding angles are congruent.
