Well if the flat fee is $4 and you pay $2 per mile and she spent a total of $32, the answer would have to be 14 miles
The first and the third equation can be solved by using the zero product property. Let us examine each equation.
4x²+16x=0
4x(x+4)=0
4x=0 and x+4=0
where x1=0 and x2=-4
Next answer is whown below:
(x+4)(x-12)=0
x1=-4 and x2=12
Therefore, the first and the third equations are the answers.
Total miles= rate x time
We can set up 2 eq:
24=(x+8)(y-4)
24=xy
Where x is equal to my original rate
and y is equal to the original time spent traveling the 2mi
We can now solve for one of the variables and find our rate
Answer:
= h
Step-by-step explanation:
Just divide both sides by pi r^2 to cancel it form the right side and you will be left with:
= h
