The amount of time it takes to finish a race might be a function of which of the following a. the distance of the race b. the number of people involved in the race c. the entry fee for the race

A. the distance of the race

Step-by-step explanation:

A race takes time to complete. The longer the race, the longer time it takes. The time it takes to complete the race does not depend on the number of people or the entry fee.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
