Anya, Jose, Cali, and Stephan walk for exercise anyas route is 2 and 1 fourth kilometers long. Jose's route is 1 and 1 half fewer Km. Calis route is 1 and 1 half times as long as Jose's route, and 2 fewer km than stephans route. What distance (d) is stephans route ?

The distance of Stephan's root is 3.125 km

Step-by-step explanation:

To solve the question we follow each of the statements individually one after the other calculating the values as we proceed.

Anya's route is 21/4 kilometers

Jose's is 11/2 fewer kilometers than Anya's routem= 21/4 -11/2 = 3/4 kilometers

Cali's route is 11/2 times as long as Jose's route which is equal to 3/4×11/2 =9/8 km or 1.125 Km

Cali's route is 2 km fewer than Stephan's route

Therefore Stephan's route is equal to 2 km +  Cali's route or = 2 + 1.125 = 3.125 km

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
