Answer:
The answer to your question is: Japan
Step-by-step explanation:
Mobile cost in Spain = € 352.5
Mobile cost in Japan = ¥39856
Exchange rate = £1 = €1.41
£1 = ¥188
Cost of mobile in pounds
£ 1 ------------------ € 1.41
x ----------------- €352.5
x = (352.5 x 1) / 1.41
x= £250
£1 ------------------ ¥188
x ----------------- -¥ 39856
x = (39856 x 1) / 188
x = £212
Then, it was cheaper in Japan
Answer:
b. ellipse; 
Step-by-step explanation:
The graph of
an ellipse because the coefficients of the quadratic terms are not the same.
This ellipse is centered at the origin. If this ellipse is translated so that its center is now at
.
Then the translated ellipse will now have equation.

We expand to get;
