Consider the following functions. Perform the operations to determine the values of a, b, c, d, and e. f(x)=(x^2+7x-12) and g(x)=(x^2-9x+1) f(x)•g(x)=ax^4-bx^3-cx^2+dx-e h(x)=(x^2+2) and k(x)=(2x^2-5x+7)
h(x)•k(x)=ax^4-bx^3-cx^2+dx-e

b.an increase in a causes b to decrease

just needed some points but try socratic

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

what is the answer?
