Shelby drew a map of the Appalachian Trail. The scale was 5 centimeters represents 400 kilometers. The map shows the Appalachian Trail to be 43.65 centimeters. What is the actual length of the Appalachian Trail?

3492km

Step-by-step explanation:If 5cm represents 400km on the scale, and the map shows 43.65cm then,

Let 5cm 400km

43.65cmu

Hence by cross multiplication,

5cmu=43.65cm × 400km

U =(43.65cm ×400km)/5cm

=(17460/5)km

=3492km

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
