Answer:
who the hells linda
Step-by-step explanation:
zzzzzzzzzzzzzzzzzz
x^2 + y^2 + 2x - 6y + 1 = 0
x^2 +2x + 1 + y^2 - 6y = 0
x^2 + 2( x × 1) + 1^2 + y^2 - 2(y×3) + 3^2 -3^2 =0
(x+1)^2 + (y-3)^2 = 3^2
comparing with circle equation
(x-a)^2 + (y - b)^2 = r^2
where (a , b) is centre of circle.
so we get center of circle is
(-1, 3)
Answer:
original price = 260
Step-by-step explanation:
original price * percent off = discount
then subtract the discount
original price - discount = new price
so
original price - original price * percent off = new price
factor out the original price
original price( 1- percent off) = new price
original price = new price/ ( 1- percent off)
lets put in what we know
original price = 182/(1-.30)
original price = 182/(.7)
original price = 260
Answer:
The average number of customers per day during the sale was 150.
Step-by-step explanation:
This question can be solved using a rule of three.
Before the sale, the average number of customers per day was 120, which is 100% = 1.
Now, there are x customers, and since it is an increase of 25%, it is 100+25 = 125% = 1.25. So
120 - 1
x - 1.25
x = 1.25*120 = 150
The average number of customers per day during the sale was 150.
