Answer:
No you do not. 
This is because we can use Pythagoras Theorem to show that our location sits outside the 15 mile radius of the cell tower.
To work is out you would write the equation 

 Then to work out the Hypotheses you would 

Which proves that the location is outside of the 15 Mile radius of the cell tower.

Answer:
 -6x+104/5
Step-by-step explanation:
Distribute: (4)(x)+(4)(5)+-10x+4/5 = 4x+20+ -10x + 4/5                                                  combine like terms: (4x+-10x) + (20+4/5)                                                                                                                                             simplify:                    -6x                  104/5                                                                     answer: -6x+104/5
