Erin lives 2 miles from school and 6 miles from her friend
Janelle. Write an inequality that describes the interval
distance from school to Janelle's house. Right, so what's your
plan? Stare at my little diagrams until it soaks in. You MAY
wish to draw a different diagram. 1) Draw a big circle - Label
it "Janelle" 2) Draw a smaller concentric circle inside the
larger circle. - Label it "School" 3) In the center of both
circles (that is just one place) put Erin. 4) From Erin, draw a
little arrow to the School circle and call it "2 miles" 5) From
Erin, draw a little arrow to the Janelle circle and call it "6
miles" In your mind, move the little arrows around their
respective circles. Pretty much like an analog clock. The
difference of their endpoints is the distance from Janelle to
School. Does it have a maximum value? Does it have a minimum
value? Think about my original diagram and it should come to you
after enough staring and pondering.
