Answer:A combination of variables, numbers, and at least one operation.
Example: x+4
Step-by-step explanation:
You would have to add x1 + x2 and divide by 2. do the same with y1 and y2.
(1/2,-1/2)
To effectively determine the correct answer, it would be helpful to write this into an algebraic expression. We let x as the number. We do as follows:
<span>Four times the square of a certain number increased by 6 times the number equals 108.
4x^2 + 6x = 108
The numbers can be either of the following since the equation generated was a quadratic equation which has two roots.
x = 4.5
x = -6 </span>
<span />x=base price
x/10=major options package
x/50=destination charge
x+x/10+x/50=24,416
x=21,800
