Answer:

(3, 0)

Step-by-step explanation:

Given system:

y = x – 3 and
y = –2x + 6

Substitute y and solve for x:

x - 3 = -2x + 6
x + 2x = 6 + 3
3x = 9
x = 3

Find y:

y = x - 3 = 3 - 3 = 0

Solution is:

(3, 0)

How do you find the area of a regular polygon?

weqwewe [10]

Each of the triangles are equal in base length, height, and area. Remember the formula for the area of a triangle. The area of any triangle is 1/2 times the length of the base (which, in the polygon, is the length of a side) multiplied by the height (which is the same as the apothem in regular polygon)
