Need help with this PLEASE! Graph the system of inequalities. Draw on the attachment to show exactly how to do it Please!

The solution in the attached figure

Step-by-step explanation:

we have

----> inequality A

The solution of the inequality A is the shaded area above the dashed line  

The slope of the dashed line is positive (m=1/4)

The y-intercept of the dashed line is (0,-3)

The x-intercept of the dashed line is (12,0)

-----> inequality B

The solution of the inequality B is the shaded area above the solid line

The slope of the solid line is negative (m=-1/2)

The x and y intercepts of the solid line is the origin

The solution of the system of inequalities is the shaded area above the dashed line and the solid line

using a graphing tool

see the attached figure

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
