Answer:

C. AB/XY = AC/XZ

Step-by-step explanation:

Dilation:

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. The original figure either stretches or shrinks by a certain factor.

In the problem, the dilation is by a factor of 5 and we can see that ABC shrinks to form XYZ.

So, ABC and XYZ are similar triangles which means that the ratio of their corresponding sides will be equal:

AB/XY = AC/XZ = BC/YZ = 5

Answer:

Q2 2010

Step-by-step explanation:

Let the number of quarters = x

Samsung increases by 6 each quarter.

Apple decreases by 1 each quarter.

Samsung

L = a + (x - 1)*6

a = 1

L = 1 + (x - 1)*6

Apple

L = a - (x - 1)*1

a = 53

L = 53 - (x - 1)*1

Now the problem is how many quarters go by until they meet?

1 + (x - 1)*6 = 53 - (x - 1) Remove the brackets

1 + 6x - 6 = 53 - x + 1 Combine like terms on both sides.

-5 + 6x = 54 - x Add 5 to both sides

6x = 59 - x Add x to both sides

7x = 59

x = 59/7 = 8 3/7

So sometime in the 8th quarter from zero they will be equal. At the end of the quarter, Samsung will be greater than Apple

So the answer should be 4 quarters from Q2 2009 or Q2 2010
