Question

The points (1,2), (5,5),(1,6) are the vertices of a shaded triangle.
a. Write a system of linear inequalities represented by the shaded triangle.
b. Find the area of the triangle.

Answer 1

well, first, draw the triangle!
it is easy to find the area, since the base is a vertical line.
Now it should be clear that one inequality is
x > 1
Now determine the equations of the other two sides, and decide whether y is above or below each line.

Answer 2

Just give us a damn answer

Answer 3

Y>3x

Answer 4

5) The following points are the vertices of a triangle: (0, –1), (4, 5), (4, –1).
a. Write a system of linear inequalities that represents the points inside the triangle.
b. Find the area of the triangle.
