Let f be the linear function f(x, y) = c + mx + ny, where c, m, n are constants and n notequalto 0. (a)Find and expand the equation of the contour that goes through the value f(x, y) = k. y = (b)Note that your equation is a line. What is the slope of the line? slope = (c)Now suppose that we look at the point (x, y) = (2,5). Find and simplify f(2,5):f(2,5) = Find and simplify f(2 + n, 5 - m): f(2 + n, 5 - m) = (d) What do you notice about your result in (c)? Confirm that this works in general by calculating f (x + m, y - n) for any x and y (simplify your expression by expanding out terms): f(x + n, y-m) = Finally, be sure that you can explain how this last result is related the the equation of the line and slope that you found in (a) and (b).

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200

452,489 to the nearest thousand is 452,000

the two may have that, even a breakdown is probably offered

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
