More of the Euler Characteristic. Suppose that the base of a pyramid is an n-gon.

Write an expression in terms of n for

38) its number of vertices, V.
39) its number of faces, F.
40) its number of edges, E.

The Euler characteristic is V + F - E.

41) What can you conclude from your expressions for exercises 38 through 40 about the Euler characteristic for pyramids?

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
