If f(x)= 5x + 4
find
the inverse of f(x)

f(x)=y

5x+4=y

5x=y-4

x=y-4/5

inverse of x=(x-4)/5

Step-by-step explanation:

y=5 x +4

X=5y+4

x-4=5 y+4-4

5y=x-4

5y/5=x-4/5

y=x-4/5

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

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to
