Answer:

1. (x + 2)² + (y - 9)² = 64

2. (x + 6)² + (y - 9/2)² = 100

3. (x - 15)² + (y + 10)² = 1

Step-by-step explanation:

Equation of a circle:

(x - h)² + (y - k)² = r²

1. Center: (-2, 9), Radius: 8

(x - (-2))² + (y - 9)² = 8²

(x + 2)² + (y - 9)² = 64

2. Center: (-6, 9/2), Radius: 10

(x - (-6))² + (y - (9/2))² = 10²

(x + 6)² + (y - 9/2)² = 100

3. Center: (15, -10), Radius: 1

(x - 15)² + (y - (-10))² = 1²

(x - 15)² + (y + 10)² = 1

Please solve ILL MARK YOU BRAINIEST!!!!!!!
sweet [91]

Answer:

14. 4 + x - 2

15. 8k - 3k

16. 5 + 2y + 15

Step-by-step explanation:

14. "sum" means adding, "minus" means subtract

sum of four and x: 4 + x

minus two: 4 + x - 2

15. "product" means multiplying, "decreased by" means subtract, "times" means multiply

the product of k and 8: 8k

three times k: 3k

the product of k and 8 decreased by three times k: 8k - 3k

(Depending on what the question is asking, you may or may not need to simplify this to 5k (8k - 3k = 5k))

16. "more" means add, "plus" means add, "twice" means multiply by two

five: 5

plus twice y:  5 + 2y

fifteen more: 5 + 2y + 15

A hotel charges $90 per day for a double room $80 per day for a single room. If a total of 80 single and double rooms are occupi
SashulF [63]

Answer:

the number of single room is 27 and the number of double room  is 53

Step-by-step explanation:

Let x is the number of single room

Let y is the number of double room

We know that:

x + y = 80 <=> x = 80 -y (1)

80x +90y= 6930 (2)

Substitute (1) in (2) we have:

80 (80 - y) + 90y = 6930

<=> 6400 - 80y +90y = 6930

<=> y = 53

> x = 80 - 53 = 27

the number of single room is 27 and the number of double room  is 53
