Answer:
x² + y² = 9
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ← r is the radius
Here r = 3, hence
x² + y² = 3² ⇒ x² + y² = 9
Answer:
Pacific Paradise deluxe state rooms=116
Caribbean Paradise deluxe state rooms = 127
Mediterranean Paradise deluxe state rooms = 333
Step-by-step explanation:
Hi, the numbers are doubled, the correct values are:
<em>Caribbean Paradise has 11 more deluxe staterooms than the Pacific Paradise.
</em>
<em>Mediterranean Paradise has 15 fewer deluxe staterooms than three times the number of deluxe staterooms on the Pacific Paradise. </em>
<em>Total number of deluxe staterooms for the three ships is 576.
</em>
So, to solve we have to write 3 equations.
C =11 +P
M = P3-15
C+M+P =576
Where:
- <em>C: number of Caribbean Paradise deluxe state rooms
</em>
- <em>M: number of Mediterranean Paradise deluxe state rooms
</em>
- <em>P: number of Pacific Paradise deluxe state rooms
</em>
Replacing values in the total ships equation:
(11 +P) + (P3-15)+P =576
Solving for P:
11 -15 +P+P+3P =576
-4 +5P =576
5P =576+4
5P =580
P = 580/5
P=116
Replacing P in each ship's equation
C = 11 +P= 11 +(116) =127
M =3P -15 = 3 (116)-15 = 333
Bye doing the pemdas equation the at 3x + -5 you get the answer

Answer:
A and B
Step-by-step explanation:
Mrs. Quotient asked her students to simplify each of the expressions below. Which of the numbered choices represents the expressions which simplified to the same result? A 126/2 B 23 × 3 C 3 × 21
When simplifying an algebraic expression, the following steps are needed to be taken.
Firstly, remove parenthesis by multiplying the constant with the term in the parenthesis or remove parenthesis using exponent rules for parenthesis in exponent form.
Secondly Combine terms by adding coefficients of terms with the same order and lastly sum all constant.
A) 126/2
Applying the division rule give:
126/2 = 63
B) 23 × 3
Applying multiplication rule gives:
23 × 3 = 69
C) 3 × 21
Applying multiplication rule gives:
3 × 21 = 63
Both the results of expression A and expression B are simplified to the same result
