Acoal car on a train weighs 30 tons plus 1 ton per cubic yard of coal x that it carries. the total weight of a coal car is: f(x) = x + 30. how will the graph of this function change if the coal car weight is changed to 26 tons?

every point will be 4 tons lower than it was

Step-by-step explanation:

26 is 4 less than 30, so the new function g(x) is ...

g(x) = f(x) -4

It is shifted down 4 units (tons) from the original function.

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
