Sarah is paying off a student loan at the rate of $900 per year. Fixed expenses:

Incomplete question. I inferred you want explanations about what are fixed expenses.

Explanation:

In accounting, the term fixed expenses apply to expenses that do not change for a considerable period of time. In other words, these expenses are fixed in nature. These expenses for example may include; rent payments,  mortgage payments,  insurance payments,  and utility expenses (electricity bills and phone bills, etc).

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
