Answer:

Step-by-step explanation:

The figures dont have enough letters to explain step by step all the exercises.

Bread 1:

The horizontal lines are parallels so both angles must be the same

2x + 21 = 4x - 17

21 + 17 = 4x - 2x

38 = 2x

x = 19

Bread 2:

Angles sum 180°

3y - 5 + 2y - 25 = 180

5y - 30 = 180

5y = 180 +30

5y = 210

y = 42

Bread 3:

Angle ABC is the same as the other 2, since x = 19

ABC = 2x + 21

ABC = 2 * 19 + 21

ABC = 59

Bread 4:

Angle ABC is the same as 3y - 5, y = 42

ABC = 3y - 5

ABC = 3 * 42 -5

ABC = 121

Bread 5:

Angles must be the same

5x - 14 = 2x + 13

5x - 2x = 13 + 14

3x = 27

x = 9

Bread 6:

Angle ABC = 5x - 14 , x = 9

ABC = 5 * 9 - 14

ABC = 31

If you need to understand why the angles must be the same just comment and I will give you more details

The average rate of change of <em>g(x)</em> over the interval [2, 8] is given by

(<em>g</em> (8) - <em>g</em> (2)) / (8 - 2)

In other words, it's the slope of the line through the points (2, <em>g</em> (2)) and (8, <em>g</em> (8)).

Use the definition of the function to evaluate it at the points in the numerator:

• 8 ≥ 4, so using the second piece, <em>g</em> (8) = -0.5(8) + 8 = 4

• 2 < 4, so <em>g</em> (2) = 5(2) + 1 = 11

Then the average rate of change is

(<em>g</em> (8) - <em>g</em> (2)) / (8 - 2) = (4 - 11) / 6 = -7/6
