Step-by-step explanation:
observing the graph
we know that
For the interval of x------>
-----> the cost is

For the interval of x------>
-----> the cost is 
For the interval of x------>
-----> the cost is 
In this problem we have
hours and
minutes
therefore
the value of x belong to the interval ![(3,4]](https://tex.z-dn.net/?f=%283%2C4%5D)
the cost is 
To start with, write both fractions with same denominator, i.e LCM of 6 and 7
Thus,
4/7=24/42
1/6=7/42
This means 4/7 is greater than 1/6
The answer is thus a
Answer:
, 
Step-by-step explanation:
To get the coefficients, we first need to factor the expressions



The coefficient of x is -16


The coefficient of x² is 10
