Answer:
The equation of the circle having centre (-5,-9) and radius r=3 is
x² + 10 x +y² + 14 y + 65 = 0
Step-by-step explanation:
<u>Explanation</u>:-
From graph The centre of the circle C( -5 , -7)
The radius of the circle r = 3cm from the centre of the given circle
The equation of the circle
From graph the centre ( h, k) = ( -5,-7) and r = 3cm
x² + 10 x +25 +y² + 14 y + 49 =9
x² + 10 x +25 +y² + 14 y + 49 -9=0
The equation of the circle
x² + 10 x +y² + 14 y + 65 = 0

Let us assume cost of one serving of pancakes = $x
So, the cost of two serving of pancakes = 2 times of x = $2x.
Given cost of the fruit cup = $1.50
Ordered two servings of pancakes and a fruit cup.
Total billed amount = $11.50.
We can setup an equation now,
Cost of two serving of pancakes + cost of the fruit cup + 15%tip = $11.50.
2x + 1.50 + 15% of (2x+1.50) = 11.50.
2x+1.50 + 0.15*(2x+1.50) =11.50
2x+1.50 +0.30x + 0.225 =11.50
Combining like terms
2.30x + 1.725 =11.50
Subtracting 1.725 from both sides
2.30x + 1.725-1.725 = 11.50-1.725
2.30x = 9.775
Dividing both sides by 2.30.
2.30x/2.30 = 9.775/2.30.
On simplifying we get,
x= 4.25.
Therefore, the cost of one serving of pancakes = $4.25.

Answer: Y goes up by non-linear rate since it is being multiplied by 4, anytime something is being multiplied is it no longer linear.
