The equations of the two circles can also be written as follows: (x-1)²+(y+2)²=16 and (x+2)²+(y+1)²=14. graph the circles and the line joining their points of intersection.

(x,y)=(-0.0464,-0.86) & (-2.15,-5.45)

Step-by-step explanation:

Given

circle

center of circle is (1,-2)

second circle

center of circle is (-2,-1)

Solving Two circles we get

y=3x+1 Put it any circle

(x,y)=(-0.0464,-0.86) & (-2.15,-5.45)

56

step-by-step explanation:

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
