Answer:
x,y ⇒x+10, y+10
Step-by-step explanation:
from looking at the graphs we can see there is only horizontal and vertical translations
take any point, for example the point C and it's transformed counterpart C'
and determine the change in x and y position
the point is translated 10 right and 10 up
so from x,y ⇒x+10, y+10
Nikita's distance from her for the second part of the race was 1.5 kilometers.
Since Nikita ran a 5-kilometer race in 39 minutes (0.65 of an hour) without training beforehand, and in the first part of the race, her average speed was 8.75 kilometers per hour, while for the second part of the race, she started to get tired, so her average speed dropped to 6 kilometers per hour, to determine which expression represents Nikita's distance for the second part of the race the following calculation must be performed:
- 8.75 x 0.65 + 6 x 0 = 5.68
- 8.75 x 0.50 + 6 x 0.15 = 5.275
- 8.75 x 0.40 + 6 x 0.25 = 5
-
100 = 60
- 40 = X
- 40 x 60/100 = X
- 24 = X
- 39 - 24 = 15
- 15 = 1/4 hour
- 6/4 = 1.5
Therefore, Nikita's distance from her for the second part of the race was 1.5 kilometers.

Answer:
The average rate in miles per hour is 8 miles per hour
Step-by-step explanation:
In this question, we are concerned with finding what Marco’s average rate is, if he cycles 20 miles in 2 1/2 hours
For calculation simplification, we should know that 2 1/2 hours is same as 2.5 hours
Now mathematically, the average speed = Distance/Time
Thus, our disgrace here is 20 miles and our time taken to cover this distance is 2.5 hours
Thus, the average speed = 20/2.5 = 8 miles/hour
