You have travelled 25 kilometres.
your friend's map gives the scale as:
20cm: 100km.
how many cm on the map have you travelled?

5cm

Step-by-step explanation:

okay what you need to know is that:

1cm:5km

5km times 5 is the distance you traveled, 25km

1cm times 5 is 5

Don't get confused with 5km to 5.

It's totally different.

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
