Answer: C
Step-by-step explanation:
You can write each term into a fraction.
becomes
When you multiply 2 terms with the same base, you add the exponents.
is also the same as
You get this because . When you pull out 5 os x, you are left with x³ on the inside.
Given:
The graph of cost of taxi with respect to number of miles.
To find:
The formula for C in terms of n.
Solution:
In the given graph x axis represents the number of miles (n) and y-axis represents the cost of taxi (C).
From the given graph it is clear that, the line passes through the points (0,3) and (5,6). So, the equation of line is
Adding 3 on both sides, we get
Putting y=C and x=n, we get
Therefore, the required formula is .
