What is the sum of the interior angles of the polygon below? Sorry for the bad quality, my computer does that a lot.

just draw a diagonal of the figure and you note it turns into two triangles.

hence sum = 2 × 180= 360 degree

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

answer: c

(2, -4)

goes 7 to the

(9, 4)
