Write the equation of a circle with a center at (-2, 3) and a radius of 4.
(x + 2)^2 + (y - 3)^2 = 4
(x - 2)^2 + (y + 3)^2 = 4
(x - 2)^2 + (y + 3)^2 = 16
(x + 2)^2 + (y - 3)^2 = 16
Answers
Answer:
The equation of a circle:
\((x+2)^2+(y-3)^2 = 16\)
Step-by-step explanation:
The equation of a circle:
\((x-h)^2+(y-k)^2 = r^2\)
(where the center is known as \((h,k)\) and the radius, known as \(r\)).
-Since you already have the center and the radius, use them for the equation of a circle:
Center: \((-2,3)\)
Radius: \(4\)
\((x+2)^2+(y-3)^2 = 4^2\)
After you have the equation of a circle, simplify the radius by the exponent \(2\) :
\((x+2)^2+(y-3)^2 = 16\)
So, you have found the equation of a circle.

Answer:
\(x=-6\dfrac{7}{8}\)
Step-by-step explanation:
\(Solve\:9\:\dfrac{1}{4}\:+\:x\:=\:2\:\dfrac{3}{8}\)
Step 1:
Convert all mixed fractions to improper fractions.
This will make it easier to add and subtract
Mixed fraction \(a\dfrac{b}{c}\) can be converted to an improper fraction using
\(a\dfrac{b}{c}=\dfrac{a\cdot \:c+b}{c}\)
\(9\dfrac{1}{4}=\dfrac{9\cdot 4+1}{4} = \dfrac{37}{4}\)
\(2\dfrac{3}{8}=\dfrac{2\cdot 8+3}{8} =\dfrac{19}{8}\)
Step 2:
Replace every mixed fraction in the original equation with its equivalent improper fraction:
\(\dfrac{37}{4}+x=\dfrac{19}{8}\)
Step 3
Solve for x
\(\dfrac{37}{4}+x-\dfrac{37}{4}=\dfrac{19}{8}-\dfrac{37}{4}\)
Simplify:
\(x =\dfrac{19}{8}-\dfrac{37}{4}\)
To calculate the right side value, multiply \(\dfrac{37}{4}\) by 2 on both numerator and denominator. This will get the denominator as 8 for both fractions and we can simply subtract the numerator:
\(\begin{aligned}x & = \dfrac{19}{8} - \dfrac{37 \times 2 }{4 \times 2} \\ & = \dfrac{19}{8} - \dfrac{74}{8}\\& = \dfrac{19 - 74}{8}\\& = - \dfrac{55}{8}\\\end{aligned}\\\\\)
\(\mathrm{Convert\:to\:mixed\:number:\:Quotient\dfrac{Remainder}{Divisor}}\)
55 goes into 8 six times so the whole part(quotient) is 6
Remainder = 55 - 8 x 6 = 55 - 48 = 7
So the fractional part = remainder/divisor = 7/8
Result:
\(x=-6\dfrac{7}{8}\)

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answers
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

You are given a triangle with side lengths of 6, 9, and 12. Is the triangle a right triangle? How do you know?
Answers
Answer:
No, it's not
Step-by-step explanation:
You choose the longest side which is 12 and apply the theory of phitagors
The longest side which is the hypotenuse in a right triangle = square root the square sum for each side
So to be a right triangle it should be
\( \sqrt{ {9}^{2} + {6}^{2} } = 10.8 \: \: that \: doesnt \: equal \: 12\)
So it's not a right triangle.
Look at the famous right triangle whose side are 5(hypotenuse), 4, 3
\( \sqrt{ {4}^{2} + {3}^{2} } = 5\)
So it's a right triangle
Right triangle lengths can be checked by the Pythagorean theorem.
This states that a^2+b^2=c^2
a and b are the shorter side lengths, and they form the right angle. c is the hypotenuse, and is the longest length.
Input the values to check if the equation checks out:
6^2+9^2=12^2
36+81=144
117≠144
No, it is not a right triangle. Hope this helps!

Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.
