oksian1 [2.3K]

Answer:

The center is at ( (-1, -2) and the radius is 5.

Step-by-step explanation:

X^2 + 2X + Y^2 + 4Y = 20

Complete the square on the x and y terms.

(x + 1)^2 -1 + (y + 2)^2 - 4 = 20

(x + 1)^2 + ( y + 2)^2 = 25  Comparing this with the standard form:

(x - h)^2 + (y - k)^2 = r^2

- the center is at ( (-1, -2) and thr radius is 5.

Answer:

Arithmetic sequence

f(n) = 5n + 2

Step-by-step explanation:

f(1) = 7

f(3) = 7 + 5 + 5 = 7 + (2)(5)

f(n) = 7 + (n-1)(5)

f(n) = 7 + 5n - 5

f(n) = 5n + 2

The regular price of a sweater is $43.99. It is on sale for 20% off. What is the discount?
Greeley [361]

Answer:

Final price would be $35.19.... discount is $8.80.

Soulution:

Replacing the given values in formula (a) we have:

Amount Saved = Original Price x Discount in Percent / 100. So,

Amount Saved = 43.99 x 20 / 100

Amount Saved = 879.8 / 100

Amount Saved = $8.8 (answer).

In other words, a 20% discount for a item with original price of $43.99 is equal to $8.798 (Amount Saved)
