Answer:
x² +y² = 73
Step-by-step explanation:
x - y = 5 ; xy = 24
[tex]\sf \boxed{\bf x^2 + y^2 = (x -y)^2 + 2xy}[/tex]
= 5² + 2*24
= 25 + 48
= 73
Reason:
x² + y² = (x - y)² + 2xy
= x² + y² - 2xy + 2xy {(x - y)² = x² +y² - 2xy}
= x² + y²

Anothony says that the expression abc has three terms because it uses three different variables. Critique Anothony's reasoning and explain whether he is correct.
According to the mathematical notations, we can say that in this case, Antonhy's reasoning is incorrect, because the expression abc is only one term and not three as he stated.
What are the terms of an expression?It corresponds to a term that has letters and numbers, which are separated only if there is a mathematical sign between them, such as the plus or multiplication sign, for example, to be an expression of three terms, the expression should be like this:

Find Dy/Dx By Implicit Differentiation. x/y +y/x = 3y
The derivative of y with respect to x (Dy/Dx) can be found by using implicit differentiation and is equal to (x/y)(Dx/Dx) / (3y - x - y).
The given equation is x/y + y/x = 3y.
To find the derivative of y with respect to x (Dy/Dx), we will use implicit differentiation.
First, we will take the derivative of both sides of the equation with respect to x:
(1/y) * (Dy/Dx) + (1/x) * (Dy/Dx) + (y/x^2) * (Dx/Dx) = (3)(Dy/Dx)
We can simplify this expression by combining the terms with Dy/Dx and Dx/Dx:
(Dy/Dx)(1/y + 1/x + 3) = (y/x^2)(Dx/Dx)
Now we can solve for Dy/Dx by rearranging the equation:
Dy/Dx = (y/x^2)(Dx/Dx) / (1/y + 1/x + 3)
Finally, we can plug in our known values and solve for Dy/Dx:
Dy/Dx = (x/y)(Dx/Dx) / (3y - x - y)
Therefore, the derivative of y with respect to x (Dy/Dx) can be found by using implicit differentiation and is equal to (x/y)(Dx/Dx) / (3y - x - y).

I know the sum of the exterior angles and interior angles is 360 and I know I need to do something with substitution but I have no idea where to start. Please explain it step by step so I understand.
The value of x in the quadrilateral is 23.
How to find the angles of a quadrilateral?A quadrilateral is a polygon with 4 sides. The sum of interior angles in a quadrilateral is 360 degrees.
The sum of external angles of any polygon, irrespective of the number of sides is 360∘.
Therefore, the value of x of the quadrilateral can be found as follows:
6x + x + 16 + 3x - 1 + 5x = 360
combine like terms
6x + x + 3x + 5x + 16 - 1 = 360
15x = 360 - 15
15x = 345
divide both sides by 15
x = 345 / 15
x = 23

A right triangle has coordinates A (4,6) , B (4, 12) and C (8, 6) . Write the coordinates of the triangle after a dilation of 12 .
The coordinates of the triangle after dilation are A'(48, 72), B'(48, 144) and C'(96, 72).
What is Dilation?Dilation is a type of transformation where the figure is enlarged or made smaller such that it preserves the shape but not size.
Every dilated image are similar figures to the original figure.
Assume that the dilation is about the origin.
When a point (x, y) is dilated with k, then new coordinates are (kx, ky).
A(4, 6) after dilation become (4 × 12, 6 × 12) = A'(48, 72)
B(4, 12) after dilation become (4 × 12, 12 × 12) = B'(48, 144)
C(8, 6) after dilation become (8 × 12, 6 × 12) = C'(96, 72)

Consider the function f(x) = 10x² - 10x.
a. Determine, without graphing, whether the function has a minimum value or a maximum value.
b. Find the minimum or maximum value and determine where it occurs.
c. Identify the function's domain and its range.
The graph is shown below.
===================================================
Explanation:
Part A)
x² is the same as x^2
The function f(x) = 10x^2-10x is the same as y = 10x^2-10x
Compare this to the template y = ax^2+bx+c to find the following
a = 10b = -10c = 0The value of 'a' is positive, which means the parabola opens upward. Furthermore, it tells us that the graph has a lowest point. There is no highest point since both parts of the parabola go upward forever.
-----------------------------
Part B)
We'll use the values of 'a' and b found earlier to get...
h = -b/(2a)
h = -(-10)/(2*10)
h = 10/20
h = 0.5
The min value therefore occurs when x = 0.5, which is the x coordinate of the vertex. The vertex being (h,k)
To find the value of k, we plug x = 0.5 into the original function.
y = 10x^2-10x
y = 10(0.5)^2-10*0.5
y = -2.5
This is the smallest the output y values can get. Therefore, it is the minimum value.
The vertex is located at (h,k) = (0.5, -2.5)
-----------------------------
Part C)
With any quadratic function, the domain is "set of all real numbers". We don't have to worry about things like...
Division by zero errors.Taking the square root of negative values.And so on.
The range is [tex]\text{y} \ge -2.5[/tex] since we found y = -2.5 to be the smallest y value possible. See part B above. So either y = -2.5 or y > -2.5
Check out the graph below. I used GeoGebra to make it, but you could use Desmos or other similar graphing tools if you prefer.

Answer:
The answer would be g(x) = -4|x| - 3

With transformations involving translating an absolute value function down, the translation would be outside the absolute value and is negative (since we're moving the entire graph down). As the transformation occurs after the graph is already reflected, the translation will not be affected by the reflection.
