Asw= 2
7:1=7 x1=7
7-7=0+3=3
The answer is +3
Well, I have never seen a question posed this way, but let's check it out by trial and error.
1^3 = 3
2^3 = 8
3^3 = 27 Hey! There's one. And the ones digit ends in 3.
Let's try another number that ends in 3 and see if it works as well.
13^3 = 2197 Wow. It works again. I never noticed this before, so you taught me something new.
I will test one more.
33^3 = 35937 Bingo. I think we have a winner.
Answer:

Step-by-step explanation:
see the attached figure to better understand the problem
Let
c -----> the cost of some taxi journeys
n ----> the number of miles
we know that
The graph is a line
The equation of a line in slope intercept form is

where
m is the slope
b is the c-intercept (value of c when the value of n is equal to zero)
Observing the graph we have the points
(0,2.5), (5,5.5)
<em>Find the slope</em>
The formula to calculate the slope between two points is equal to
substitute the values
we have
-----> because the point (0,2.5) is the c-intercept
substitute in the equation of slope-intercept form
