Help! Please
1. Consider the triangular region in the plane given by the triangle (1, 6), (6, −1), and (1, −4).
Sketch the region, and write a system of inequalities to describe the region bounded by the triangle.
2. Consider the quadrilateral with vertices (−2, −1), (2, 2), (5, −2), and (1, −5).
What is the equation of the perpendicular bisector of the side of the quadrilateral that lies in the fourth quadrant?
3. Line contains points ( − 4, 2) and (−2, 9). Line contains points (, −1) and (−1, 1).
A. Find the value of if the lines are parallel.
B. Find the value(s) of if the lines are perpendicular.

uhhh idk u yolo?

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.

sorry

step-by-step explanation:

sorry, but im pretty sure its a now that i look at it
