4 0

Answer: You use it to represent that the equation your graphing is either greater than or equal too or less than or equal too

Step-by-step explanation:

A dotted line is there to represent that the equation your graphing is either grater than or less than

So the solid line represents the same thing, except that they both have a possibility of being equal too which is why the line is solid.

I hope this helps!

melissa and brian are at the base of a moutain. melissa hikes to a location 27 meters above sea.level brian hikes to a location
sweet [91]

Answer:

The difference is 48 meters

Step-by-step explanation:

<u><em>The question is</em></u>

What is the difference of the hikers' altitudes?

Let

x -----> the Melissa's altitude in meters

y ----> Brian's altitude in meters

we have that

x=+27\ ft ---> is positive because is above sea level

y=-21\ ft ---> is negative because is below sea level

Remember that the sea level is the altitude equal to zero

<em>Find the difference</em>

To find out the difference of the hikers' altitudes, subtract Brian's altitude from Melissa's altitude

so

27-(-21)

Remember that (-1)(-1)=+1

27+21=48\ m
