A’B’C’ is a dilation image if ABC which is the correct description of the dilation
Sav [38]

Answer:

The dilation is an enlargement

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor

In this problem Triangles A'B'C' and ABC are similar by AA Similarity Postulate

Let

z------> the scale factor

so

z=\frac{A'C'}{AC}

substitute the values

z=\frac{2+8}{2}

z=\frac{10}{2}=5

The scale factor is greater than 1

therefore

The dilation is an enlargement

How does finding the square root of a number compare to finding the cube root lf a number? Use the number 64 in your explainatio
xenn [34]

If you want to know the concept of square roots and cube roots ?

the square root of a number is that number which when multiplied by itself two times gives us that number

e.g.

√64 = x , so that (x)(x) = 64

and from our multiplication table we know that

(8)(8) = 64 , so that

√64 = 8

the cube root of a number is that number which when multiplied by itself three times gives us that number

e.g.

∛64 = x , so that (x)(x)(x) = 64 , and thus x = 4 because 4x4x4 = 64

so ∛64 = 4

Need help on graphing problem
aivan3 [116]
J is your answer.

Slope is rise over run + your Y intercept.

Your y- intercept is the point in the graph in which the line passes through, the line passes through -2, so you know -2 is going to be your answer at the end. And slope is rise/run.

From one point to another, you rise 1 time , and run over 3 so you know your answer is

y = 1/3x - 2

hope this helps :)
