Answer:

c=\frac{3}{5}(n)+2.5

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

c=m(n)+b

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

m=\frac{c2-c1}{n2-n1}

substitute the values

m=\frac{5.5-2.5}{5-0}

m=\frac{3}{5}

we have

b=2.5 -----> because the point (0,2.5) is the c-intercept

substitute in the equation of slope-intercept form

c=\frac{3}{5}(n)+2.5

I don't know what I am doing help please (C:
NeX [460]

Answer:

Step-by-step explanation:

The far right side of the triangle is 17 cm, which is the height.

The base would be 34 minus 17 because whole length of the rectangle is 34 and the triangle covers all but 17 of it.

So then you would take 1/2 of 17.

Then multiply it by 17 to get 160.5
