Solve the system of equations. x+y=4 y=x^2 - 8x + 16 a) {(-3,, 8)} b) [(4,0)} c) {(3,,0) d) {(3,7). (4.0)} e) none

 The required solution of the given system is

(x, y) = (3, 1)  and  (4, 0).

Step-by-step explanation:  We are given to solve the following system of equations :

From equation (i), we have

Substituting the value of y from equation (iii) in equation (ii), we get

When, x = 3, then from (iii), we get

And, when x = 4, then from (iii), we get

Thus, the required solution of the given system is

(x, y) = (3, 1)  and  (4, 0).

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
