Find the equation for the circle with a diameter whose endpoints are (5,5) and (3,−5).
The equation of the circle in standard form whose center is at (h, k) = (4, 0) is (x - 4)² + y² = 26.
How to derive the standard equation of the circle based on the coordinates of diameter endpoints
In this question we find the coordinates of the endpoints of the diameter of the circle, then, the center of the circle is the midpoint of the line segment. The center of the circle is found by midpoint formula:
(h, k) = 0.5 · (5, 5) + 0.5 · (3, - 5)
(h, k) = (4, 0)
And the radius of the circle is determined by Pythagorean theorem:
r = √[(4 - 5)² + (0 - 5)²]
r = √[(- 1)² + (- 5)²]
r = √26
Then, the equation of the circle in standard form is describe below:
(x - h)² + (y - k)² = r²
If we know that (h, k) = (4, 0) and r = √26, then the equation of the circle is:
(x - 4)² + y² = 26

First of all, we have to find the mean of x values.
According to the given graph, the x values are: 0, 1, 2, 2, 3, 3, 4, 5, 6, 7.
So, the mean is
[tex]\bar{x}=\frac{0+1+2+2+3+3+4+5+6+7}{10}=\frac{33}{10}=3.3[/tex]The mean of x values is 3.3.
The y values are: 2, 2, 3, 4, 4, 4, 5, 6, 8, 9.
The mean would be
[tex]\bar{y}=\frac{2+2+3+4+4+4+5+6+8+9}{10}=\frac{44}{10}=4.4[/tex]The mean of y values is 4.4.

For given equation y = -2x + 8, the x-intercept is (4, 0) and the y-intercept is (0, 8)
In this question, we have been given an equation y = -2x + 8
We need to find the x-intercept and y-intercept. Also, we need to write it as a coordinate (a, b)
To find the x-intercept we need to substitute y = 0 in the above equation.
0 = -2x + 8
2x = 8
x = 4
So, the x-intercept is (4, 0)
To find the y-intercept we need to substitute x = 0 in the above equation.
y = -2(0) + 8
y = 0 + 8
y = 8
So, the y-intercept is (0, 8)
Therefore, for given equation y = -2x + 8, the x-intercept is (4, 0) and the y-intercept is (0, 8)

x<−1A teacher is organizing binders for her students. She has 54 pieces of lined paper, 36 pieces of grid paper, and 72 dividers. What is the greatest number of identical binders that she can make? Please help!
Using the highest common factor, the greatest number of identical binders that the teacher can make is 18.
What is the highest common factor?The highest common factor or multiple of the given numbers is the highest number that can divide them without a remainder.
We know that 2, 9, and 18 can divide 54, 36, and 72 without leaving a remainder.
We can see that the highest common factor is 18.
When we divide 54 by 18, the quotient is 3. If you divide 36 by 18, the quotient is 2. When you divide 72 by 18, the result is 4.
The number of lined paper = 54 pieces
The number of grid paper = 36 pieces
The number of dividers = 72 dividers
The common factors of 54, 36, and 72 are 2, 9, and 18.
The highest common factor of 54, 36, and 72 is 18.

Draw a graph for each side, or component, of the equation and check to see where the curves intersect or are equal, to solve an equation graphically. The answers to the equation are the x values of these places.
Consider the equation,
x³ + 5x² = - x² + 5x + 3
Solving Equations Graphically:
The solution(s) of the equation f(x) = g(x) are the values of x where the graphs of f and g intersect.
Therefore,
f(x) = x³ + 5x² and g(x) = - x² + 5x + 3
By graphing the function we find the intersection of the two functions.
Hence, the graphs intersect each other at ( - 0.411, 0.776) and ( 1.092, 7.268).

An election ballot asks voters to select six city commissioners from a group of twenty two candidates. In how many ways can this be done?
In this case, we have 6 places to fill from a pool of 22 candidates. There is no difference in the places: they are all commissioners, so if candidate A is selected, the order does not matter, but there is only one candidate, so there is no repetition.
Then, this is a combination (as the order does not matter) with no repetition of 22 elements in 6 places.
We can calculate this as:
[tex]\begin{gathered} C(n,r)=\frac{n!}{r!(n-r)!} \\ C(22,6)=\frac{22!}{6!(22-6)!}=\frac{22!}{6!\cdot14!}=\frac{22\cdot21\cdot20\cdot19\cdot18\cdot17\cdot16\cdot15}{6\cdot5\cdot4\cdot3\cdot2\cdot1}=17907120 \end{gathered}[/tex]Answer: there are 17,907,120 ways this can be done.

The value of x is 4.
The perimeter of any shape is the sum of lengths of all its sides.
We are provided with the sides of triangle i.e., 5x-1, 5x-1 and 2.2x +10.
So, The perimeter of a triangle = sum of length of all three sides = (5x-1) + (5x-1) + (2.2x +10)
The perimeter of a triangle = 12.2x + 8 equation 1
Also, we are provided with the side of square i.e., 6.5x -11.8.
The perimeter of a square = 4 (side) = 4 (6.5x - 11.8)
The perimeter of a square = 26x - 47.2 equation 2
As per question,
Perimeter of a triangle = Perimeter of a square
12.2x + 8 = 26x - 47.2

Horatio left a campsite, hiking at a rate of 1 mile per hour. Ivan left 3 hours later, hiking at a rate of 2 miles per hour. How long will it take Ivan to catch up to Horatio?
Ivan will catch up to Horatio in 3 hours .
In the question ,
it is given that
speed of Horatio is 1 miles per hour
speed of Ivan is 2 miles per hour .
and Ivan leaves 3 hours late than Horatio .
Let "t" be the time ( in hours ) taken for Ivan to meet Horatio ,
So, the distance covered by Ivan will be 2*t .
Since Horatio left 3 hours before so the time taken for Horatio to meet Ivan is (t+3).
So, the distance covered by Horatio will be 1*(t+3) .
The distance covered for Horatio and Ivan will be equal ,
which means
2*t = 1*(t+3)
2t = t + 3
2t - t = 3
t = 3

solve for y
2x+y=3
Answer:
y = 3 - 2x
Step-by-step explanation:
Subtract 2x from both sides of the equation.
Answer:
y = x or 1x
Step-by-step explanation:
x as a variable can also be expressed as 1x.
so we can say that 2x + 1x
because x & y are two different type of variables. you think of y as a question mark ( ? ).
Now the new equation is
y = ?
so 1x + ? = 3
because x is the same thing as a 1x you can say that 2x + 1x = 3

The height of balloon is 1.99 miles above the ground.
What is angle of depression ?In the event when the line of sight is directed downhill from the horizontal line, an angle is created with it. Angle of depression is the angle produced between the horizontal line and the observer's line of sight when the object being observed is below the level of the observer.
Let's give the balloon's height above the earth and the distance it is from the first milepost horizontally a name.
We can state the following if the angle of this milepost's depression is 24 degrees:
Tan(24)=[tex]\frac{h}{b}[/tex]
b = [tex]\frac{h}{tan(24)}[/tex]

They can sell their candy for $3 a box. If we jet x represent the boxes of candy sold, the number of
boxes they need to sell to break even can be found by solving the equation 3x + 500 = 3x. How
many boxes of candy to they need to sell to break even?
You can never achieve break even by selling any number of boxes of candy if it costs them an additional $3 to manufacture each box of candy.
What is Break even point?In economics, business, and particularly cost accounting, the break-even point is the point at which total cost and total income are equal, or "even."
Although these opportunity costs have been paid and then capital has received the risk-adjusted, projected return, there is no net loss or gain, and one has "broken even."
Fixed cost (in manufacturing) = $500
Manufacturing cost of each candy = $3
and selling price of candy = $3
let x be a box of candy sold,
hence for no of box to be sold for a break even,
3x + 500 = 3x
but if you see above equation, that has no solution
Hence by providing each candy at $3 with $500 fixed cost and selling cost again at $3 you cannot achieve a break-even point.
hence there is no solution, and you will never be able to achieve break even.

The value for the height of the rectangular prism is found as; h = 7.
What is defined as the rectangular prism?A rectangular prism is a three dimensional solid shape with six faces that have rectangles as their bases. Right rectangular prisms as well as non-right (oblique) rectangle prisms are the two types of rectangular prisms. The right rectangle prism does have two parallel end faces and 4 lateral faces, each of which is an rectangle; this same faces are perpendicular to the bases of the prism.The formula for the surface area of rectangular prism is;
S = 2(ab+bh+ah)
Where,
a=6, b=5 and s=214
Substitute the values in the formula.
214 = 2(6×5 + 5h + 6h)
Simplifying;
30 + 11h = 107
11h = 107 - 30
