Answer:
<em> -- When going</em>
<em> -- When coming back</em>
Step-by-step explanation:
Given
![Speed\ to = 7mi/hr](https://tex.z-dn.net/?f=Speed%5C%20to%20%3D%207mi%2Fhr)
![Speed\ from = 3mi/hr](https://tex.z-dn.net/?f=Speed%5C%20from%20%3D%203mi%2Fhr)
![Distance = 2\ mi](https://tex.z-dn.net/?f=Distance%20%3D%202%5C%20mi)
Required
Determine time taken to your friend's house
Determine time taken from your friend's house
Distance is calculated as:
![Time = \frac{Distance}{Speed}](https://tex.z-dn.net/?f=Time%20%3D%20%5Cfrac%7BDistance%7D%7BSpeed%7D)
From the question, we understand that:
![Distance = 2\ mi](https://tex.z-dn.net/?f=Distance%20%3D%202%5C%20mi)
When going:
![Speed\ to = 7mi/hr](https://tex.z-dn.net/?f=Speed%5C%20to%20%3D%207mi%2Fhr)
So, we have:
![Time = \frac{2mi}{7mi/hr}](https://tex.z-dn.net/?f=Time%20%3D%20%5Cfrac%7B2mi%7D%7B7mi%2Fhr%7D)
![Time = \frac{2}{7}hr](https://tex.z-dn.net/?f=Time%20%3D%20%5Cfrac%7B2%7D%7B7%7Dhr)
Express in Minutes
![Time = \frac{2}{7} * 60](https://tex.z-dn.net/?f=Time%20%3D%20%5Cfrac%7B2%7D%7B7%7D%20%2A%2060)
![Time = \frac{120}{7}](https://tex.z-dn.net/?f=Time%20%3D%20%5Cfrac%7B120%7D%7B7%7D)
![Time = 17.143\ mins](https://tex.z-dn.net/?f=Time%20%3D%2017.143%5C%20mins)
When coming back:
![Speed\ from = 3mi/hr](https://tex.z-dn.net/?f=Speed%5C%20from%20%3D%203mi%2Fhr)
![Time = \frac{2mi}{3mi/hr}](https://tex.z-dn.net/?f=Time%20%3D%20%5Cfrac%7B2mi%7D%7B3mi%2Fhr%7D)
![Time = \frac{2}{3}hr](https://tex.z-dn.net/?f=Time%20%3D%20%5Cfrac%7B2%7D%7B3%7Dhr)
Express in Minutes
![Time = \frac{2}{3} * 60](https://tex.z-dn.net/?f=Time%20%3D%20%5Cfrac%7B2%7D%7B3%7D%20%2A%2060)
![Time = \frac{120}{3}](https://tex.z-dn.net/?f=Time%20%3D%20%5Cfrac%7B120%7D%7B3%7D)
![Time = 40\ mins](https://tex.z-dn.net/?f=Time%20%3D%2040%5C%20mins)

just try to divide by those and if you an, then it isn't prim
A. 15/3=5 so not prime
B. 49/7=7, not prime
C. 9/3=3 not prime
D. all prime
answe ris D
This function is in vertex form: f(x)=a(x-h)^2 - k
Where (h , k) is the vertex. x=h is the axis of symmetry.
