Step-by-step explanation:
equation of circle ](https://tex.z-dn.net/?f=%28x-x_1%29%5E2%2B%28y-y_1%29%5E2%3Dr%5E2%3C%2Fp%3E%3Cp%3Ewhere%20r%3Dredius%20of%20circle%2C%5Btex%5D%28x_1%2Cy_1%29)
is centre of circle
centre of circle=(-5,3)
put the value of centre and redius in the equation
equation of circle 
=4^2
8x-19=-3x-41
+3x +3x
11x-19=-41
+19 +19
11x=-22
÷11 ÷11
x=-2
6-2x=6x-10x+20 solve for x
combine like terms and get all to the same side of equation
6-2x+10x-6x=20
10x-2x-6x+6=20
8x=20-6
8x=14
x=14/8=7/4

Answer:
₹1000
Step-by-step explanation:
Let m represent the marked price. After the discount, the price is 0.80m. After the tax is added, the price is (0.80m)(1.13). This value is Rs 904, so the marked price is ...
(0.80m)(1.3) = ₹904
m = ₹904/(0.80×1.13) = ₹904/0.904
m ≈ ₹1000
The marked price of the watch is ₹1000.
