The question is an illustration of a system of linear equations.
- The system of linear equations is:
and 
- The solution to the equation is (25,500)
Let the number of miles be x.
<u>Getting trained and licensed</u>
- One time cost: $450
- Gas and Insurance: $2 per mile
So, the equation is:

<u>Delivery</u>
- First delivery: $350
- Rate: $6 per mile
So, the equation is:

Hence, the system of linear equations is:
and 
To solve the equation, we equate both, as follows:

Collect like terms


Divide both sides by 4

Substitute 25 for x in 



Hence, the solution to the equation is (25,500)

-36 i think i dont really know sry!! :(
Answer:
1/2
Step-by-step explanation:
The slope is given by
m = (y2-y1)/(x2-x1)
= (6 - -1)/(12 - -2)
= (6+1)/(12+2)
7/14
