josh filled up the gas tank on his truck and decided to collect some data tht he could use to determine the fuel efficiency of his vehicle . Here is a table with the data that he collected . gallons of gas in the tank 18 , numberes of miles driven 0, 15, 39

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

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
