If point C(-3,8) is the midpoint of a line segment with endpoints A(-9,-2) and B, what are the coordinates of point B?

Step-by-step explanation:

Compare coordinates of A and C:

difference of x-coordinates = -3-(-9) = 6

difference of y-coordinates = 8-(-2) = 10

Extrapolate to get coordinates of B:

B(-3+6, 8+10) = B(3,18)

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

its adding 5.5 each time
