Answer:
TWO CRACKERS
Step-by-step explanation:
I'm assuming they want to find x. Here we see that these two are similar triangles, so the sides are reflective. 5x/5 should be equal to 4/x, so 5x/5 = 4/x. If we use cross multiplying we get 5x^2 = 20. divide both sides by 5 and we get x^2 = 4 or x = 2.

Which linear function has the same y-intercept as the one that is represented by the graph?
On a coordinate plane, a line goes through points (3, 4) and (5, 0).
A 2-column table with 4 rows. Column 1 is labeled x with entries negative 3, negative 1, 1, 3. Column 2 is labeled y with entries negative 4, 2, 8, 14.
A 2-column table with 4 rows. Column 1 is labeled x with entries negative 4, negative 2, 2, 4. Column 2 is labeled y with entries negative 26, negative 18, negative 2, 6.
A 2-column table with 4 rows. Column 1 is labeled x with entries negative 5, negative 3, 3, 5. Column 2 is labeled y with entries negative 15, negative 11, 1, 5.
A 2-column table with 4 rows. Column 1 is labeled x with entries negative 6, negative 4, 4, 6. Column 2 is lab
eled y with entries negative 26, negative 14, 34, 46.
The linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.
To determine the linear function with the same y-intercept as the graph, we need to find the equation of the line passing through the points (3, 4) and (5, 0).
First, let's find the slope of the line using the formula:
slope (m) = (change in y) / (change in x)
m = (0 - 4) / (5 - 3)
m = -4 / 2
m = -2
Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:
y - y1 = m(x - x1)
Using the point (3, 4) as our reference point, we have:
y - 4 = -2(x - 3)
Expanding the equation:
y - 4 = -2x + 6
Simplifying:
y = -2x + 10
Now, let's check the given options to find the linear function with the same y-intercept:
Option 1: The table with x-values (-3, -1, 1, 3) and y-values (-4, 2, 8, 14)
The y-intercept is not the same as the given line. So, this option is not correct.
Option 2: The table with x-values (-4, -2, 2, 4) and y-values (-26, -18, -2, 6)
The y-intercept is not the same as the given line. So, this option is not correct.
Option 3: The table with x-values (-5, -3, 3, 5) and y-values (-15, -11, 1, 5)
The y-intercept is the same as the given line (10). So, this option is correct.
Option 4: The table with x-values (-6, -4, 4, 6) and y-values (-26, -14, 34, 46)
The y-intercept is not the same as the given line. So, this option is not correct.
Therefore, the linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.

Using principle of mathematical induction prove that 6^-1 divisble by 5 .
I suppose the claim is \(5 \mid 6^n - 1\) for \(n\in\Bbb N\).
When \(n=1\), we have \(6^1 - 1 = 6 - 1 = 5\), and of course 5 divides 5.
Assume the claim holds for \(n=k\), that \(5 \mid 6^k - 1\). We want to use this to show it holds for \(n=k+1\), that \(5 \mid 6^{k+1} - 1\).
We have
\(6^{k+1} - 1 = \left(6^{k+1} - 6\right) + \left(6 - 1) = 6\left(6^k - 1\right) + 5\)
Since \(5 \mid 6^k - 1\), we can write \(6^k - 1 = 5\ell\) for some integer \(\ell\). Then
\(6^{k+1} - 1 = 6\cdot5\ell + 5 = 5(6\ell + 1)\)

Select the statement that is false.
Select one:
a. If 4 is a prime number, then 6 is a prime number.
b. If 4 is a prime number, then 5 is a prime number.
c. If 3 is a prime number, then 5 is a prime number.
d. If 3 is a prime number, then 6 is a prime number
Out of the given statements, statement a. If 4 is a prime number, then 6 is a prime number is the false one. A prime number is a positive integer that has exactly two distinct natural number divisors: 1 and itself.
For example, the number 2 is a prime number because it can only be divided evenly by 1 and 2. 4 is not a prime number because it can be divided evenly by 1, 2, and 4. 6 can be divided evenly by 1, 2, 3, and 6, so it is not a prime number. Therefore, statement a is false because if 4 is a prime number, 6 is not a prime number.
When determining whether a number is a prime number, it is important to remember that 1 is not a prime number. This is because 1 only has one divisor - itself. Any other number that can be divided evenly by more than two distinct natural numbers is not a prime number.

Corresponding sides of similar triangles are proportional. Use this fact to find the length of side PR of the following pair of similar triangles. Remember that the length cannot be negative, and there may be more than one solution.
The length of side PR can be either 14 or 5.
Describe corresponding sides ?In geometry, corresponding sides are the sides of two or more geometric figures that are in the same relative position to each other. When two or more figures are similar, their corresponding sides are in the same ratio or proportion, meaning that the ratio of the length of one side in the first figure to the length of the corresponding side in the second figure is constant. For example, if two triangles are similar, then their corresponding sides are proportional to each other. The side that corresponds to another side is typically identified using the same letter with a prime symbol (') added to it.
Since the triangles PQR and STV are similar, their corresponding sides are proportional. That is,
PR / SV = QR / TV
Substituting the given lengths, we get:
(3x-19) / (3x-9) = (x-4) / 12
Cross-multiplying and simplifying, we get:
36x - 228 = (3x-9)(x-4)
36x - 228 = 3x^2 - 21x + 36
3x^2 - 57x + 264 = 0
Dividing both sides by 3, we get:
x^2 - 19x + 88 = 0
Factoring the quadratic equation, we get:
(x-11)(x-8) = 0
Therefore, x = 11 or x = 8.
If x = 11, then PR = 3x-19 = 3(11) - 19 = 14.
If x = 8, then PR = 3x-19 = 3(8) - 19 = 5.
Therefore, the length of side PR can be either 14 or 5.

The graph of f is translated a whole number of units horizontally and vertically to obtain the graph of h
The function f is defined by f(x) = square root of x
Write down the expression for h(x).
The expression for h(x) is,
⇒ h (x) = √(x - 2) + 4
Now, Given that;
Initially the graph f (x) is shifted horizontally to the right.
When the graph shifts to right the function then becomes
f (x) → f (x-b)
Where b is the units by which it is shifted towards right .
So, in the figure we can see that it is shifted 2 units to the right .
So, f(x) → f(x-2)
Since f(x) is,
⇒ f (x) = √x
So, f (x-2) = √x - 2
Now, the new obtained graph is again shifted vertically upward
When the graphs shifts upward;
⇒ f(x) → f(x) + b
where b is the units by which it is shifted upward
So, our obtained f(x-2) when shifted upward by 4 units so using the above given transformation of upward shift
i.e. f(x) → f(x) + b
So, Our new graph h(x) = f(x-2) + 4

Find the equations with unit rates greater than the unit rate of the graph. Then arrange these equations in order from least to greatest unit rate.
The equations in order from least to greatest unit rate are y = 13/6x,y = 11/5x, y = 21/9x and y = 19/8x
How to determine the equations with unit rates greater than the unit rate of the graph?
On a graph, the unit rate is obtained by calculating the slope of the line. The slope is the change in y divided by the change in x:
Slope = y2-y1 / x2-x1
Thus, we can any two convenient points on the graph and use it calculate the slope:
Let's pick points (5, 10) and (12, 25)
This implies x1 = 5, y1 = 10 and x2 = 12, y2 = 25
Slope = y2-y1 / x2-x1
Slope = 25-10 / 12-5 = 15/7
Thus, the unit rate of the graph is 15/7 = 2.143
Find the equations with unit rates greater than the unit rate of the graph:
y = 19/8x: unit rate = 19/8 = 2.375
y = 27/13x: unit rate = 27/13 = 2.077
y = 21/9x: unit rate = 21/9 = 2.333
y = 11/5x: unit rate = 11/5 = 2.200
y = 15/17x: unit rate = 15/17 = 0.882
y = 31/15x: unit rate = 31/15 = 2.067
y = 13/6x: unit rate = 13/6 = 2.167
The equations with unit rates greater than the unit rate of the graph are y = 19/8x, y = 21/9x, y = 11/5x and y = 13/6x
Therefore, the equations in order from least to greatest unit rate are y = 13/6x,y = 11/5x, y = 21/9x and y = 19/8x. Drag each tile to the correct box accordingly

6 divided 1/2 what’s the expression to multiply by the reciprocal
When 6 is divided by 1/2 the result is 12 because the expression to multiply by the reciprocal is 6 × 2.
What is reciprocal of a numberThe reciprocal of a number is the multiplicative inverse of that number. In other words, if you multiply a number by its reciprocal, the result is always 1.
In division by a fraction, the reciprocal of that fraction is the fraction that you multiply by to obtain the quotient hence for 6 divided by 1/2 the expression becomes;
6 ÷ 1/2 = 6 × 2/1
6 ÷ 1/2 = 12.

Which of the following are disadvantages of the mode?
For many sets of data there are multiple modes.
The mode is affected by extremely large and small values.
For many sets of data there is no mode.
the mode can only be computed for interval-level data or higher
The disadvantages of the mode are: For many sets of data there is no mode.
The mode is a measure of central tendency that represents the most frequently occurring value in a dataset.
However, one of the disadvantages of the mode is that for many sets of data, there may not be a distinct mode. In such cases, the data may have a uniform distribution where all values occur with equal frequency, or it may have multiple modes with similar frequencies.
The mode is not affected by extremely large or small values. It only considers the frequency of values and not their magnitude. Therefore, extreme values do not influence the mode.
The statement that the mode can only be computed for interval-level data or higher is incorrect. The mode can be computed for any type of data, including nominal, ordinal, interval, and ratio data. It is applicable to categorical as well as numerical data.
The main disadvantage of the mode is that for many datasets, there may not be a distinct mode.

You can use a function to describe the amount of money left in the fund after x employees receive the reimbursement.
Write an equation for the function. If it is linear, write it in the form f(x)=mx+b. If it is exponential, write it in the form f(x)=a(b)x.
The formula for this linear function is f(x) = mx + b, where m is the slope (in this example, -350), and b is indeed the y-intercept (750,000 in this case).
What does a simple equation represent?An equation expressing the connection between the expressions on either side of a sign. Normally, it has an equal sign and just one variable. such as: 2x - 4 is equal to 2. The variable x is present in the example above.
