a rectangle has a length that is 10 less than 3 times the width. if the rectangle has an area of 8 square feet, what is the width of the rectangle?

2

Step-by-step explanation:

guess and check. length is 4. That times 3 is 12. Minus 10 is 2. 4 times 2 is 8. This may not be the way the book wants you to do it but it is correct.

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
