Answer & Step-by-step explanation:

Okay, so to find all the values for x, solve the equation for x first (it's kind of long and didn't fit, sorry)

Then find the range for x based on the two equations of -y-1 and y+3. Since  this is an odd-degree polynomial, the range is all real numbers:

∈

(x is all real numbers)

Unless....

Take the given inequality    and find the range:

Add two to both sides:

Rewrite without the absolute value:

Add 1 to the whole equation:

Maybe don't trust me..

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
