Let f(x)=-2-7 and g(x)=-4+3. find (f o ) a.-53 b.23 c.-9 d.3

(A) -53

Step-by-step explanation:

g(x) = -4x + 3

g(-5) = -4(-5) + 3

       = 20 + 3

       = 23

                             f(x) = -2x - 7

                           f(23) = -2(23) - 7

                                   = -46 - 7

                                   = -53

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
