<h3>Answer: Choice B) 8.57</h3>

==================================================

Explanation:

The triangles are similar through the AA (angle angle) similarity rule. Note how the angle markers correspond and match up. Example: angle C and angle F both have triple angle markers to indicate these angles are congruent.

The corresponding sides pair up to form equal fractions. AB and DE form AB/DE which is equal to AC/DF, as these two sides correspond as well.

Therefore: AB/DE = AC/DF

Let's plug in the given values and isolate x

AB/DE = AC/DF

11/7 = (15+x)/15 ...... substitution

11*15 = 7*(15+x) ....... cross multiply

11*15 = 7*15+7*x ...... distribute

165 = 105+7x

165-105 = 105+7x-105 ..... subtract 105 from both sides

60 = 7x

7x = 60

7x/7 = 60/7 ............ divide both sides by 7

x = 8.57142857142858

x = 8.57 ..... rounding to the nearest hundredth

Answer:

  f(x) = 6x +1

Step-by-step explanation:

Differences in x-values (first row) are 1, 1, 1.

Differences in y-values (second row) are 6, 6, 6.

The constant ratio of differences (6/1) tells you the function is linear, and has a slope of m = 6/1 = 6.

Using the first point in the form ...

  y = mx + b

we have ...

  y = 6x + b

  7 = 6·1 + b . . . . (x, y) = (1, 7)

  1 = b . . . . . . subtract 6

Then the equation can be written ...

  y = 6x +1

In functional form, this is ...

  f(x) = 6x +1
