Answer:
Step-by-step explanation:
Equation:1
Equation:2
Solving Equation:1
Subtracting 'y' from both the sides:
Putting 'x' in Equation :2
Adding '4' both the sides
Putting the value of 'y' in equation:1
The solution is:
Using linear function concepts, it is found that:
a) The initial value is of 3 and the rate of change is of 20.
b) The rate of change means that for <u>each hour, the cost increases by 3 Dhs</u>, while the initial value means that <u>a flat fee of 20 Dhs is paid</u>.
<h3>What is a linear function?</h3>A linear function is modeled by:
In which:
In this problem, the function that gives the charge C for renting a bicycle for h hours is:
Item a:
Comparing to the standard function, we have that:
Item b:
The rate of change means that for <u>each hour, the cost increases by 3 Dhs</u>, while the initial value means that <u>a flat fee of 20 Dhs is paid</u>.
