Daniela rented a car. she paid a flat rate for the day, plus a cost per mile charge. the expression 0.15x+220.15x+22 represents the amount daniela paid. what do the different parts of the expression model? drag the parts of the expression into the boxes to match each description. daily flat rate cost per mile number of miles driven 22 0.15 x 0.15x

Let

x--------> the number of miles driven

y--------> the amount in dollars that Daniela paid

we know that

where

-------> represent the daily flat rate (the y-coordinate of the y-intercept of the linear equation)

-------> represent the cost per mile (the slope of the linear equation)  

---------> number of miles driven

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
