The graph shows the cost of some taxi journeys. work out a formula for C in terms of n.
Serga [27]

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

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

y-3=\dfrac{6-3}{5-0}(x-0)

y-3=\dfrac{3}{5}(x)

Adding 3 on both sides, we get

y=\dfrac{3}{5}x+3

Putting y=C and x=n, we get

C=\dfrac{3}{5}n+3

Therefore, the required formula is C=\dfrac{3}{5}n+3.

If DF+FE=DE, then point F is_________
Dima020 [189]
I believe the correct answer from the choices listed above is option A. If DF+FE=DE, then point F is <span>A. a midpoint of DE (with line over). F is the endpoint of line segment DF and is the starting point of line DE thus it is in between line DE. Hope this answers the question.</span>
