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)

Answer: A) (-1, 0) to (1, 2)
<u>Step-by-step explanation:</u>
Complex numbers are written in the form of ai + b ; where "a" represents the x-coordinate and "b" represents the y-coordinate --> (a, b)
-i → -1i + 0 → (-1, 0)
2 + i → 1i + 2 → (1, 2)
Which graph connects those two coordinates? OPTION A
