Step-by-step explanation:
The standard form of an equation of a circle:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
(h, k) - center
r - radius
We have the center (5, -3) and the radius r = 4. Substitute:

What is the image of (4,7) after a reflection over the line y= - X ?
(-4, 7) would be the answer
A reflection of the point (4,7) over the line y=-x swaps and negates the x and y coordinates which leads to the new point being (-7,-4).
The image of the point (4,7) when reflected over the line y = -x is determined by essentially flipping the x and y coordinates of the original point and negating them.
This is because a reflection over the line y = -x swaps the x and y values and takes their opposite. Thus, the original point (4,7) would evolve into the point (-7,-4) after the reflection.
To break this down, the original x value was 4, and after reflection, this becomes -7 which is the new x-coordinate.
The original y value was 7, and after reflection, this becomes -4 which is the new y-coordinate. Therefore, the image of (4,7) after the reflection over the line y = -x is (-7,-4).

gurindas previous checking account balance was $532.14. since then she has written a check for $46.19 and one for 138.32. she also made a $200 deposit into her account. assuming her monthly service charge is $6, how much is her new balance ?
Answer:
$541.63
Step-by-step explanation:
To find the balance of Gurindas, we need to break down our values.
Checking Balance = $532.14
Checks = $-46.19 + $-138.32 = $-184.51
Deposit = $200
Service Charge = $-6
Now to find her new balance, we simply add them all together.
New Balance = 532.14 + -184.51 + 200 + -6
New Balance = $541.63
In Spencer's garden, the number of rose bushes is 7 less than 1.5 times the number of carnation bushes. If the number of carnation bushes is c, then the expression representing the number of rose bushes is .
Answer:
1.5c-7=n
Step-by-step explanation:
Answer:
The required expression is 1.5c-7
Step-by-step explanation:
Here, c represents the number of carnation bushes,
Since, the number of rose bushes is 7 less than 1.5 times the number of carnation bushes,
That is, the number of roses = 1.5c - 7
Hence, the required expression that represents the number of roses is 1.5c - 7.

Answer:
[tex]y=-\frac{3}{5} x+6[/tex]
Step-by-step explanation:
Lets solve the equation [tex]3x+5y=30[/tex] for [tex]y[/tex] step-by-step:
Step 1. Subtract [tex]3x[/tex] from both sides of the equation
[tex]3x+5y=30[/tex]
[tex]3x-3x+5y=-3x+30[/tex]
[tex]5y=-3x+30[/tex]
Step 2. Divide both sides of the equation by 5
[tex]\frac{5y}{5} =\frac{-3x+30}{5}[/tex]
[tex]y=\frac{-3x+30}{5}[/tex]
[tex]y=-\frac{3}{5}x+\frac{30}{5}[/tex]
[tex]y=-\frac{3}{5} x+6[/tex]
We can conclude that the equation that can be used for solve for [tex]y[/tex] is [tex]y=-\frac{3}{5} x+6[/tex]
Answer:
y = -3x/5 + 6
Step-by-step explanation:
Given the equation 3x+5y = 30, to find the equation that can be used to solve for y, we will have to make y the subject of the formula from the given linear equation to have;
3x + 5y = 30
First we will subtract 3x from both sides of the equation to have;
3x+5y-3x = 30-3x
5y = 30-3x
Dividing both sides of the equation by the coefficient of y which is 5 we will have;
5y/5 = 30/5-3x/5
y = 6-(3x/5)
y = -3x/5 + 6
A bakery gave out coupons to celebrate its grand opening. Each coupon was worth either $1, $3, or $5. Twice as many $1 coupons were given out as $3 coupons, and 3 times as many $3 coupons were given as $5 coupons. The total value of all the coupons given out was $360. How many $3 coupons were given out?
Answer:
54
$3 dollar coupons were given
Step-by-step explanation:
We can represent this question as a system of equations
Let
x = number of $1 dollar coupons
y = number of $3 dollar coupons
z = number of $5 dollar coupons
Twice as many $1 coupons were given out as $3 coupons,
x = 2*y
3 times as many $3 coupons were given as $5 coupons.
y = 3*z
The total value of all the coupons given out was $360
x*$1 + y*$3 + z*$5 = $ 360
The system results
x - 2y + 0 = 0 (1)
0 + y - 3z = 0 (2)
x + 3*y +5*z = $ 360 (3)
We substitute equation (2) and (1) into (3)
(2y) + 3*y + 5*(y/3) = $ 360
20*y/3 = 360
y = 54
To determine the number of $3 coupons given out by the bakery, we solved the equation 5x + 3(3x) + 1(2(3x)) = $360, where x represents the number of $5 coupons. We found that x = 18, and since there are three times as many $3 coupons as $5 coupons, the bakery gave out 54 $3 coupons.
The question involves solving a system of linear equations to determine how many $3 coupons were given out by the bakery. Let's define the variables first:
x = number of $5 coupons3x = number of $3 coupons2(3x) = number of $1 couponsBased on the given information, we can set up the following equations:
5x + 3(3x) + 1(2(3x)) = $360Now let's solve the equation:
5x + 9x + 6x = $36020x = $360x = 18Once we have x, we know that the number of $3 coupons is 3 times x, so:
3x = 3(18) = 54
Therefore, 54 $3 coupons were given out by the bakery.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the equation A is
3x - 7y = 41 be equation (1)
x = -2y - 21 be equation (2)
Now , substitute the value of equation (2) in equation (1) , we get
3x - 7y = 41
3 ( -2y - 21 ) - 7y = 41
On simplifying the equation , we get
-6y - 63 - 7y = 41
Adding 63 on both sides of the equation , we get
-13y = 104
Divide by -13 on both sides of the equation , we get
y = -8
So , the value of y = -8
Substitute the value of y in equation (2) , we get
x = -2y - 21
x = - 2 ( -8 ) - 21
x = 16 - 21
x = -5
So , the value of x = -5
Therefore , the value of x is -5 and y is -8
Hence ,
The value of x = -5
The value of y = -8

The equation of a circle is x^2 + y^2 -4x + 2y - 11 = 0. What are the center and the radius of the circle? Show your work.
Answer:
The center of the circle;
(2, -1)
The radius of the circle;
r = 4
Step-by-step explanation:
The first step is to complete the square on both x and y;
x^2 + y^2 -4x + 2y - 11 = 0
x^2 -4x +y^2 +2y = 11
We determine c1 to complete the square on x;
c1 = (b/2)^2
c1 = (-4/2)^2 = 4
We then determine c2 to complete the square on y;
c2 = (2/2)^2 = 1
The equation of the circle is then re-written as;
x^2 -4x + 4 +y^2 +2y + 1 = 11 +4 +1
We then factorize the expressions in x and y separately;
(x-2)^2 + (y +1)^2 = 16
The center of the circle is thus;
(2, -1)
The radius is the square root of 16;
r = 4
find the attached.
Answer:
Center at (-2, -1) and radius = 4
Step-by-step explanation:
We are given the following equation of a circle which we want to convert into the standard form:
[tex]x^2+y^2-4x+2y-11=0[/tex]
Note that
(x + a)² = x² + 2ax + a²
so that
x² + 2ax = (x + a)² - a²
So [tex]x^2+y^2-4x+2y-11=0[/tex]
[tex]x^2-4x+y^2+2y=11[/tex]
[tex](x-2)^2-2^2+(y+1)^2+1^2=11[/tex]
[tex](x-2)^2+(y+1)^2-5=11[/tex]
[tex](x-2)^2+(y+1)^2=16[/tex]
Therefore, this equation represents a circle with center at (-2, -1) and radius √16 = 4, as shown below.

Arrange the numbers in decreasing order of their values.
Answer:
The numbers in decreasing order of their values are:
[tex]\cfrac{19}{3}>\sqrt{37}>6.08171...>6.012[/tex]
Step-by-step explanation:
Before actually comparing, we need to write all of those numbers in decimal form, that will be the only way to actually tell which one is bigger since you are already given numbers in decimal form.
Converting numbers in decimal form.
The first number we are given is [tex]\sqrt{37}[/tex], we know it is a bit higher than 6, since the square root of 36 is 6, so using a calculator we get
[tex]\sqrt{37}=6.0828[/tex]
The second number is a fraction, in decimal form will be:
[tex]\cfrac{19}{3}= 6.3333[/tex]
Writing the decreasing order.
Now that all numbers are in decimal form we can compare them and write them in decreasing order.
[tex]6.3333... > 6.0828...>6.08171...>6.012[/tex]
Lastly we can write the decreasing order using the numbers on their original form.
[tex]\cfrac{19}{3}>\sqrt{37}>6.08171...>6.012[/tex]
