Answer:

x = -1, y = 1

Step-by-step explanation:

- The function in the form y = f(u) is y = f(5x)., - The function in the form u = g(x) is u = 5x.

To find the function in the form y = f(u) and u = g(x), we can start by identifying the expressions for y and u given in the question:

y = 5x
u = ?

Since u = g(x), we need to find the expression for u in terms of x. In this case, u is not explicitly given, but we can see that y is already in terms of x. Therefore, we can directly substitute the expression for y into the equation for u:

u = y = 5x

Now, we have the expression for u in terms of x. However, the question asks for u as a function of x. So, we need to rewrite the expression in terms of a variable other than u:

u = 5x

This is our final answer in the form of u = g(x). The function relating y and x can be written as y = f(u). Since u = 5x, we can substitute this expression into the function to find y in terms of x:

y = f(u) = f(5x)

So, the function relating y and x is y = f(5x).

In summary:
- The function in the form y = f(u) is y = f(5x).
- The function in the form u = g(x) is u = 5x.

Remember, always verify your steps and check if the given functions and expressions match the question requirements.

A quadratic function for the area of a figure can be represented as \(A(x) = ax^2 + bx + c,\) where a, b, and c are constants and x is the side length of the figure.

\(A(x) = x^2 - 6x + 9\\A(7) = (7^2) - (6\times 7) + 9 \\= 49 - 42 + 9 = 16\)

In this case, the given value of x is 7, so the area of the figure can be found by plugging 7 into the equation. \(A(7) = a(7^2) + b(7) + c = 49a + 7b + c.\)

Therefore, the area of the figure for \(x = 7 , 49a + 7b + c.\)

The quadratic equation can also be used to calculate the area of the figure for any given value of x.

To do this, simply plug in the desired value of x into the equation and solve for the area.

For example, if we want to find the area of the figure for x = 4, then we would plug 4 into the equation and solve for the area. \(A(4) = 16a + 4b + c\).

This shows that the area of the figure for x = 4 is 16a + 4b + c.

In summary, the quadratic equation \(A(x) = ax^2 + bx + c\) can be used to calculate the area of a figure for any given value of x.

For the given value of x = 7, the area of the figure is calculated to be \(49a + 7b + c.\)

To compute the median of these fourteen patients' lengths of stay, we need to arrange them in ascending order first: 1, 1, 2, 2, 3, 3, 4, 4, 4, 4, 5, 6, 16. Then, we can find the middle value, which is 4, since there are an even number of values. Therefore, the median length of stay for these fourteen patients is 4.

The median is a measure of central tendency that represents the middle value of a dataset. In this case, we have fourteen patients' lengths of stay, which we need to arrange in ascending order before finding the middle value. Once we have arranged them, we can easily find the median, which is 4. This means that half of the patients stayed for less than 4 days, and half stayed for more than 4 days. The median is a useful measure when the dataset has outliers or extreme values that could affect the mean. In this case, we have one patient who stayed for 16 days, which is much longer than the other patients' lengths of stay. The median is not affected by this extreme value, making it a robust measure of central tendency.

In conclusion, the median length of stay for these fourteen patients is 4. By arranging the lengths of stay in ascending order and finding the middle value, we can determine the central tendency of this dataset. The median is a useful measure when dealing with datasets that have outliers or extreme values, as it is not affected by them. In this case, we have one patient who stayed for much longer than the others, but the median is still a reliable measure of the typical length of stay for these fourteen patients.

Answer:

(-3/2, -13/2)

Step-by-step explanation:

To solve the system of equations graphically, we need to plot the two equations on the same set of axes and find the point of intersection.

To plot the first equation y = x - 5, we can start by finding the y-intercept, which is -5. Then, we can use the slope of 1 (since the coefficient of x is 1) to find other points on the line. For example, if we move one unit to the right (in the positive x direction), we will move one unit up (in the positive y direction) and get the point (1, -4). Similarly, if we move two units to the left (in the negative x direction), we will move two units down (in the negative y direction) and get the point (-2, -7). We can plot these points and connect them with a straight line to get the graph of the first equation.

To plot the second equation y = -x - 8, we can follow a similar process. The y-intercept is -8, and the slope is -1 (since the coefficient of x is -1). If we move one unit to the right, we will move one unit down and get the point (1, -9). If we move two units to the left, we will move two units up and get the point (-2, -6). We can plot these points and connect them with a straight line to get the graph of the second equation.

The point of intersection of these two lines is the solution to the system of equations. We can estimate the coordinates of this point by looking at the graph, or we can use algebraic methods to find the exact solution. One way to do this is to set the two equations equal to each other and solve for x:

x - 5 = -x - 8 2x = -3 x = -3/2

Then, we can plug this value of x into either equation to find the corresponding value of y:

y = (-3/2) - 5 y = -13/2

So the solution to the system of equations is (-3/2, -13/2).

Taxpayers in California may need to calculate the itemized deduction limitation when filing their state income taxes. This limitation sets a cap on the amount of itemized deductions that can be claimed, based on the taxpayer's federal adjusted gross income (AGI) and other factors.

Calculating the California itemized deduction limitation involves several steps and considerations to ensure compliance with the state tax regulations. To calculate the California itemized deduction limitation, taxpayers should first determine their federal AGI. This can be found on their federal tax return. Next, they need to identify any federal deductions that are not allowed for California state tax purposes, as these will be excluded from the calculation. Once the applicable deductions are determined, taxpayers must compare their federal AGI to the threshold specified by the California Franchise Tax Board (FTB). The limitation is typically a percentage of the federal AGI, and the percentage may vary depending on the taxpayer's filing status. If the federal AGI exceeds the threshold, the itemized deductions will be limited to the specified percentage. Taxpayers should consult the official guidelines and instructions provided by the California FTB or seek professional tax advice to ensure accurate calculation and compliance with the state tax regulations. Calculating the California itemized deduction limitation is an important step in accurately reporting and calculating state income taxes. It helps determine the maximum amount of itemized deductions that can be claimed, ensuring that taxpayers adhere to the tax laws and regulations of the state.

Answer:

(- 3, 12 ) and (5, 28 )

Step-by-step explanation:

Given the 2 equations

y = x² + 3 → (1)

y - 2x = 18 → (2)

Substitute y = x² + 3 into (2)

x² + 3 - 2x = 18 ( subtract 18 from both sides )

x² - 2x - 15 = 0 ← in standard form

(x + 3)(x - 5) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 5 = 0 ⇒ x = 5

Substitute these values into (1) for corresponding values of y

x = - 3 : y = (- 3)² + 3 = 9 + 3 = 12 ⇒ (- 3, 12 )

x = 5 : y = 5² + 3 = 25 + 3 = 28 ⇒ (5, 28 )
