For the given equation, find the center and radius of the circle
x2 + (y + 3)2 = 49

Step-by-step explanation:

×2+(y+3) 2=49

2×y=2y=2×3=6

49-2=47

2y=47-6=41

2y=41÷2=20 1/2

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
