> don’t have to show the number line< 1) find the distance between -8 and 2 on a number line 2) use a number line to model: 2/5+(-1/5) 3) explain how you find the least common denominators between 3/4 and 5/12 4) if sudeep ran 8 1/4 miles on monday, 10 2/5 on tuesday and only 7 5/8 miles on wednesday. estimate how many miles he ran in those three days to the nearest whole mile. i will mark you as brainliest if u answer the right thing! and don’t answer if u don’t know; -;

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

where is the picture
