Erica bought 1 5/8 yards of wrapping paper from the gift shop, as shown by the shaded part of the model below. After the wrapping a gift Erica had 1 1/4 yards of wrapping paper left. How much wrapping paper did Erica use to wrap the gift. Use the model to help you solve.

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

1. perpendicular

2. parallel

3. perpendicular

the answer is 6

hope this !
