True.
Angle c=anglez
Angle RHC=angle XHZ
Therefore they’re similar.

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.

Step-by-step explanation:
we have
![y=3x-1](https://tex.z-dn.net/?f=y%3D3x-1)
we know that
If the point is an equation solution, it must satisfy the equation.
<u>case a</u>) ![(4,1)](https://tex.z-dn.net/?f=%284%2C1%29)
Substitute the values of x and y in the equation
![1=3*4-1](https://tex.z-dn.net/?f=1%3D3%2A4-1)
![1=12-1](https://tex.z-dn.net/?f=1%3D12-1)
-------> the point is not solution of the equation
<u>case b</u>) ![(2,5)](https://tex.z-dn.net/?f=%282%2C5%29)
Substitute the values of x and y in the equation
![5=3*2-1](https://tex.z-dn.net/?f=5%3D3%2A2-1)
![5=6-1](https://tex.z-dn.net/?f=5%3D6-1)
-------> the point is solution of the equation
<u>case c</u>) ![(4,3)](https://tex.z-dn.net/?f=%284%2C3%29)
Substitute the values of x and y in the equation
![3=3*4-1](https://tex.z-dn.net/?f=3%3D3%2A4-1)
![3=12-1](https://tex.z-dn.net/?f=3%3D12-1)
-------> the point is not solution of the equation
<u>case d</u>) ![(0,-3)](https://tex.z-dn.net/?f=%280%2C-3%29)
Substitute the values of x and y in the equation
![-3=3*0-1](https://tex.z-dn.net/?f=-3%3D3%2A0-1)
-------> the point is not solution of the equation
therefore
<u>the answer is</u>
The point
is solution of the equation
