In exercise sketch the graph of the function.
f(x) = e - 2x + 1

Attached linear graph

Step-by-step explanation:

The value of e is a mathematical constant of 2.72 approximately. We can consider this a constant as 1. Therefore this is a straight line with a gradient/slope of -2 and a y-intercept of:

and x intercept of:

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
