2b. Yes True
2c. Yes True
2d. No False
Step-by-step explanation:
The answer is 105 degrees! They are alternate exterior which means they are congruent! Also, they form vertical angles when you set them next to each other :)
Total number of hours she schduled to play the game = 3
hours.
Let us convert mixed fraction into improper fraction

Duration of each round =
.
In order to find the number of rounds Nicole can play, we need to divide total number of hours by duration of each round.
÷ 
Converting division sign into multiplication flips the second fraction.

Crossing out 12 by 4, we get 3 on the top of second fraction.


Because problem is about number of rounds.
So, total number of round would be 5.
The last one, v = -2,000y + 20,000
Answer: The graph is attached.
Step-by-step explanation:
1. Solve for y, as following:

2. The equation of the line in slope intercept form is:

Where m is the slope and b is the y-intercept.
3. In this case the equation of the line is:

then:

4. Find the x-intercept. Make y=0. Then:

5. Then, plot the line that passes through the points (0,7) and (4.9, 0).
6. The symbol of the inequality is < therefore, the line must be dashed and indicates that the region under the line must be shaded.
Then you obtain the graph attached.
