It takes 8 minutes for jess to fill the kiddie pool in the backyard using only a handheld hose. when his younger sister is impatient, bryon also uses the law sprinkler to add water to the pool so it is filled more quickly. if the hose and sprinkler are used together, it takes 5 minutes to fill the pool which equation can be used to determine r, the rate in parts per minute, at which the lawn sprinkler would fill the pool if used alone?

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

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
