208 in^2

find the area of each of the parts (4 triangles and 1 square)

all of the triangles have the same area since this is a square pyramid
area of triangle = (base X height)/2
so it would be (8 X 9)/2 = 36

for the square, the area is length X width
so it would be 8 X 8 = 64

add all the areas
36+36+36+36+64 = 208

6) Write a system of linear inequalities that is given by the following graph.

Answers

Answer:

The system of inequalities are x - y < 1 and y < - 2 The horizontal line shown in the graph has equation y = - 2 {As it is parallel to x-axis} Now, this line is dotted and the lower portion of the graph is shaded. So, the inequality will be y < - 2 ......... (1) Again, another line is there in the graph which passes through the points (1,0) and (0,-1)So, its equation will be

⇒ y + 1 = x ⇒ x - y = 1 Now, the origin (0,0) is within shaded zone of the inequality and putting x = 0 and y = 0, we get 0 - 0 < 1 So, the equation of the inequality is x - y < 1 {As the line is dotted} Therefore, the system of inequalities are x - y < 1 and y < - 2 (Answer)
