Could Someone help me, thank you so much!

approximately 60 pages

Step-by-step explanation:

because based on the scatter plot it's slowly going up each chapter it would make no sense for it to be 10 that's too little 170 and 100 are definitely to far away, therefore 60 is the best option

Hope this helps dude

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
