So we have to factor this expression:
\(-\frac{1}{3}x+\frac{2}{3}\)Using the leading coefficient of the variable term. The variable term is that with x and the leading coefficient is the number multiplying the x, in this case:
\(-\frac{1}{3}\)What we are going to do now is take the term that is not the variable term and multiply and divide it by the leading coefficient:
\(\begin{gathered} \frac{2}{3}=\frac{2}{3}\cdot\frac{-\frac{1}{3}}{-\frac{1}{3}}=\frac{2}{3}\cdot(-\frac{1}{3})\cdot(-\frac{3}{1})=\frac{2}{3}\cdot(-3)\cdot(-\frac{1}{3}) \\ \frac{2}{3}=(-2)\cdot(-\frac{1}{3}) \end{gathered}\)Then we get:
\(-\frac{1}{3}x+\frac{2}{3}=-\frac{1}{3}x+(-2)\cdot(-\frac{1}{3})\)Now that both terms are multiplied by the same number we can factor the expression:
\(-\frac{1}{3}x+(-2)\cdot(-\frac{1}{3})=-\frac{1}{3}\cdot(x-2)\)Then the answer is:

Pythagorean Theorem: a2 + b2 = c2
a farmer wants to fence in three sides of a rectangular field shown below with 960 feet of fencing. The other side of the rectangle will be a river. If the enclosed area is to be a maximum, find the dimensions of the field.
9514 1404 393
Answer:
240 ft by 480 ft
Step-by-step explanation:
Area is maximized when the long side is half the total length of the fence. That makes the short side (out from the river) be half the length of the long side.
The fenced field dimensions are 240 feet by 480 feet.
__
You can let x represent the length of the long side. Then the length of the short side is half the remaining fence: (960 -x)/2.
The total area is the product of these dimensions:
A = x(960 -x)/2
We note that this is the equation of a parabola with zeros at x=0 and x=960. The maximum will be found on the line of symmetry, halfway between the zeros. That is at x = (0 +960)/2 = 480.
The area is maximized for a long-side dimension of 480 feet. The short sides are 240 feet.
If y = x then dy, the differential of y, as a changes from 64 to 64.1 is given
by
Answer:
\(dy \ = \ 0.1\)
Step-by-step explanation:
Considering the Leibniz notation to represent the derivative of \(y\) with respect to \(x\), suppose \(y \ = \ f\left(x\right)\) is a differentiable function, let \(dx\) be the independent variable such that it can be designated with any nonzero real number, and define the dependent variable \(dy\) as
\(dy \ = \ f'\left(x\right) \ dx\),
where \(dy\) is the function of both \(x\) and \(dx\). Hence, the terms \(dy\) and \(dx\) are known as differentials
Dividing both sides of the equation by \(dy\), yield the familiar expression
\(\displaystyle\frac{dy}{dx} \ = \ f'\left(x\right)\).
Given that \(f\left(x\right) \ = \ x\) and \(dx \ = \ 64.1 \ - \ 64 \ = \ 0.1\), hence
\(f'\left(x\right) \ = \ 1\).
Subsequently,
\(dy \ = \ f'\left(64\right) \ \times \ 0.1 \\ \\ dy \ = \ 1 \ \times \ 0.1 \\ \\ dy \ = \ 0.1\).

In the following diagram, ABCDABCD is a square. The coordinates of the vertices A,B,CA,B,C and DD are (3,3),(8,3),(8,8)(3,3),(8,3),(8,8) and (3,8)(3,8) respectively.
The square is dilated from the origin by a factor of 1111 to give A′B′C′D′A′B′C′D′.
What are the coordinates of point C′C′? (NEED THIS ASAP)
Answer:
Step-by-step explanation:
To dilate the square by a factor of 1111 from the origin, we need to multiply each coordinate by 1111.
The coordinates of point C are (8,8). So, to find the coordinates of point C' after dilation, we can simply multiply each coordinate by 1111:
x-coordinate of C' = 1111 * 8 = 8888
y-coordinate of C' = 1111 * 8 = 8888
Therefore, the coordinates of point C' are (8888, 8888).
a bernoulli differential equation is one of the form observe that, if or , the bernoulli equation is linear. for other values of , the substitution transforms the bernoulli equation into the linear equation consider the initial value problem (a) this differential equation can be written in the form with 1/x , 5 , and 2 . (b) the substitution y^-1 will transform it into the linear equation -1/x -5 . (c) using the substitution in part (b), we rewrite the initial condition in terms of and : 1/5 . (d) now solve the linear equation in part (b), and find the solution that satisfies the initial condition in part (c).
The Bernoulli differential equation is a nonlinear ordinary differential equation of the form:
dy/dx + P(x)y = Q(x)y^n, where n ≠ 0, 1.
For n = 0 or n = 1, the equation is linear. For other values of n, a common technique to linearize the equation is to make the substitution y = v^(-1/n-1). The resulting equation is:
dv/dx + (P(x) + Q(x)/v^(1/n-1)) * (1/n-1) * v^(1/n-2) * dv/dx = 0.
For the initial value problem given, we have P(x) = -1/x, Q(x) = -5, and n = 2.
We make the substitution y = v^(-1), so v = y^(-1), and dv/dx = -y^(-2)dy/dx. The equation becomes:
-y^(-2)dy/dx + (-1/x - 5y^2) = 0.
We have the initial condition y(1) = 1/5. In terms of v, the initial condition becomes v(1) = 1/(1/5)^2 = 25.
Now, the differential equation is linear, and we can solve it using standard methods, such as separation of variables. To find the solution that satisfies the initial condition, we may use numerical methods such as the Euler method or Runge-Kutta method.

Isabel sells new and used mystery novels online. Her customers are primarily in the United States. She sends up to 10 pounds of books in one shipment. She uses the United States Postal Service’s Media Mail service because it is inexpensive for her customers. Current Media Mail shipping prices for book shipments weighing 10 pounds or less appear below.
Isabel’s competition,who sells books and no other products, charges a shipping fee of $1.99 per book plus a fixed fee of $3 for each order. Let x be the number of books purchased and f(x) be the price of shipping one order of books. Write a function that expresses f(x) and explain the value of f(x) for x = 0. (5 points)
Graph the function in part e. (10 points)
Is your graph discrete or continuous? Explain. (5 points)
The function that expresses f(x) can be written as:
f(x) = 3 + 1.99x
where 3 represents the fixed fee per order and 1.99x represents the cost of shipping per book.
For x = 0, the value of f(x) is simply the fixed fee per order:
f(0) = 3
The graph of the function f(x) is a straight line with a slope of 1.99 and y-intercept of 3
The graph is continuous because the function f(x) is defined for all values of x within its domain, which is all non-negative integers. However, the values of f(x) are discrete because they only take on certain specific values (i.e., multiples of $1.99 + 3$).
Given f(x) and g(x) = k • f(x), use the graph to determine the value of k.

help please g
Answer:
the solution to the equation -2a - 6a - 9 = -9 - 6a - 2a is all real numbers, or (-∞, +∞).
Step-by-step explanation:
To solve this equation for "a", you need to simplify and rearrange the terms so that all the "a" terms are on one side of the equation and all the constant terms are on the other side. Here are the steps:
Start by combining the "a" terms on the left side of the equation: -2a - 6a = -8a. The equation now becomes: -8a - 9 = -9 - 6a - 2a.
Combine the constant terms on the right side of the equation: -9 - 2a - 6a = -9 - 8a. The equation now becomes: -8a - 9 = -9 - 8a.
Notice that the "a" terms cancel out on both sides of the equation. This means that the equation is true for any value of "a". Therefore, the solution is all real numbers, or in interval notation: (-∞, +∞).
In summary, the solution to the equation -2a - 6a - 9 = -9 - 6a - 2a is all real numbers, or (-∞, +∞).
