What sort of equation would that be?The definition of the an equation in algebra is a logical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
What about the equation's meaning?A mathematical equation, such as 6 × 4 = 12 x 2, states that two quantities or values are equal. A noun that counts. When two or more components must be taken into account together in order to comprehend or describe the whole situation, this is known as an equations.
To find the equation of the axis of symmetry for the parabola[tex]y = x^2 - x - 6,[/tex] we first need to find the x-coordinate of the vertex.
We can use the formula [tex]x = -b/2a[/tex] to find the x-coordinate of the vertex. In this case, a = 1 and b = -1, so:
[tex]x = -(-1) / 2(1) = 1/2[/tex]
So the x-coordinate of the vertex is [tex]1/2[/tex].
To find the y-coordinate of the vertex,
x = 1/2
[tex]y = (1/2)^2 - (1/2) - 6 = -25/4[/tex]
So the coordinates of the vertex are [tex](1/2, -25/4).[/tex]
[tex]x = 1/2[/tex]
Therefore, the equation of the axis of symmetry is [tex]x = 1/2.[/tex]

find the domain of the function f(x)=7x+5/3x-1
The domain of the function f(x)=7x+5/3x-1 is all real numbers except x = 1/3. This means that the function will produce a real number for any value of x except for x = 1/3.
What is a function?Function in mathematics is a relation which assigns each element of a set (called the domain) to exactly one element of another set (called the codomain). It can also be thought of as a type of mapping from one set to another. Functions are used to model real-world problems and to simplify the expression of a certain problem. They are widely used in algebra, trigonometry and other areas of mathematics.
The domain of a function is the set of all possible inputs for the function. In other to determine the domain of a function, we must first identify the independent variable (x) and then determine which values of x can be used in the function.
In the given function, f(x)=7x+5/3x-1, the independent variable is x. To find the domain of this function, we must identify the values of x that will produce results that are real numbers. To do this, we must set the denominator (3x-1) equal to zero and solve for x.
We can solve this equation by factoring and setting each factor equal to zero:
3x - 1 = 0
3x = 1
x = 1/3
Therefore, the domain of the function f(x)=7x+5/3x-1 is all real numbers except x = 1/3. This means that the function will produce a real number for any value of x except for x = 1/3.

For the graph of the rational function the as x → −∞, f(x) → −∞.
What are rational functions?A rational function is the ratio of two polynomial functions with a non-zero denominator polynomial. R(x) = P(x)/Q(x), where P(x) and Q(x) are polynomial functions, is the standard representation of this relationship. We studied the rational number idea in previous grades. When the denominator is not equal to zero, it is the quotient or ratio of two integers. Rational, then, is a name that comes from the term ratio.
From the given graph we observe that as the value of x tends to - ∞, the value of f(x), that is, the value of y constantly goes upwards and leftwards.
Thus,
As x → −∞, f(x) → −∞.
Hence, for the graph of the rational function the as x → −∞, f(x) → −∞.

60°
2√6
Oz=4√6.y=6√2
Oz= 8√3,y=6
= 4√6, y=6
Oz=6√2y = 8√3
Thus, the length of the missing side for the given Right triangles using the Trigonometric Ratios is found as :x = 18.47 units.
What is meant by Trigonometric Ratios?In order to examine the sides of both a right triangle, which will depend on an acute angle, trigonometric ratios are used. Right triangles what about those produced by the intersection of the legs, which have an internal angle of 90 degrees. We can determine the right triangle's missing sides or sharp angles using trigonometric ratios.The leg, denoted as, that is next to the 30 degree angle θ is represented by Side BC. To get the length of side BD, the hypotenuse of triangle BCD, we use the cosine ratio.
cos θ = Adjacent leg / Hypotenuse = BC/BD
cos 30° = 8√2 / BD
Now, we know.
cos 30° = √3/2
√3/2 = 8√2 / BD
BD = 8√2 / √3/2
BD = 16√2 / √3
On rationalising;
BD = 16√2*√3 / √3*√3
BD = 16√6 / 3
Sin A = Opposite leg /Hypotenuse = BD / x
Sin 45° = (16√6 / 3) / x = 16√6 / 3x
We know that:
Sin 45° = 1/√2
(1/√2) = 16√6 / 3x
(1/√2) * x = 16√6 /3
Or,
√2/2 * x = (16√6 /3) * (2/√2)
x = 32√3 / 3
x = 18.47
Thus, the length of the missing side for the given Right triangles using the Trigonometric Ratios is found as :x = 18.47 units.

What kind of transformation converts the graph of f(x)=2|x|+4 into the graph of g(x)=|x|+2?
reflection across the y-axis
reflection across the x-axis
Vertical stretch
Vertical Shrink
Answer:
The transformation that converts the graph of f(x)=2|x|+4 into the graph of g(x)=|x|+2 is a Vertical Shrink.
To see this, note that the 2 in f(x) causes a vertical stretch of the absolute value graph. Removing the 2 in g(x) results in a Vertical Shrink of the absolute value graph. The +4 and +2 only cause a vertical shift of the graph.
Answer: Vertical Shrink
Step-by-step explanation:
The transformation that converts the graph of f(x)=2|x|+4 into the graph of g(x)=|x|+2 is a vertical shrink.
To see why, let's examine each function separately:
The function f(x) = 2|x| + 4 has an absolute value in its equation, which means it has a "V" shape. The coefficient 2 in front of the absolute value means that the "V" is stretched vertically by a factor of 2. The constant 4 added to the end of the function moves the entire graph up by 4 units.The function g(x) = |x| + 2 also has an absolute value in its equation, but without a coefficient in front of it. This means that the "V" shape is not stretched or shrunk vertically. The constant 2 added to the end of the function moves the entire graph up by 2 units.Therefore, the transformation from f(x) to g(x) involves removing the vertical stretch by dividing the absolute value term by 2. This results in a smaller "V" shape for the graph of g(x), or a vertical shrink.
The answer is:
[tex]$\boxed{\text{Vertical Shrink}}$[/tex]

Find the function that is finally graphed after the following transformations are applied to the graph
1) Reflect about the x axis
2) shift up 9 units
3) shift left 9 units
After reflection and shifts, all three transformations gives us the final function: y = -√(x+9) + 9. This function starts at the point (-9,9) and decreases as x increases. The graph of this function is a reflection of the original graph of y = √x about the x-axis, shifted up by 9 units, and shifted left by 9 units.
What is the function after reflection about x - axisThis function starts at the origin (0,0) and increases as x increases.
1. Reflect about the x axis:
A reflection about the x-axis takes every point on the graph of y = √x and maps it to a new point with the same x-coordinate, but the opposite y-coordinate. For example, the point (1,1) on the graph of y = √x would be reflected to the point (1,-1) on the new graph. This transformation effectively flips the graph upside down.
2. Shift up 9 units:
This transformation moves the entire graph up by 9 units. Every point on the graph is shifted vertically by 9 units. For example, the point (1,-1) on the reflected graph would be shifted up to the point (1,8) on the new graph.
3. Shift left 9 units:
This transformation moves the entire graph to the left by 9 units. Every point on the graph is shifted horizontally by 9 units. For example, the point (1,8) on the shifted graph would be shifted left to the point (-8,8) on the final graph.
Combining all three transformations gives us the final function: y = -√(x+9) + 9.

Which of the following characteristics would best describe a sample that enables you to draw accurate inferences from the sample? A. The sample is biased, but not random or representative. B. The sample is random, but not biased or representative. C. The sample is random and representative, but not biased. D. The sample is random, representative, and biased.
Answer:
The best option that describes a sample that enables you to draw accurate inferences from the sample is option C: "The sample is random and representative, but not biased."
A random sample is one in which every member of the population has an equal chance of being selected. This helps to ensure that the sample is not influenced by any outside factors that could skew the results.
A representative sample is one that accurately reflects the characteristics of the population it is drawn from. This ensures that the results obtained from the sample can be generalized to the larger population.
However, if the sample is biased, it may not accurately represent the population. This could lead to inaccurate inferences and conclusions.
Therefore, a random and representative sample that is not biased is the best option for drawing accurate inferences from the sample.

**Jackie took out a mortgage loan for $90,000 at an interest rate of 10% for 25 years. If Jackie had not filed a bankruptcy, which damaged her credit score a lot, her payments could have been much lower at $527.16 per month. How much is Jackie paying in additional interest over the life of the loan?
Hint: 1st, use minimum monthly payment formula: to calculate the monthly payment at 10% interest rate, where PV = 90,000, i = 0.10/12, and n = 300 (because that is how many months there are in 25 years).
2nd, once you find P multiply it by 300 months to find how much Jackie paid for the lifetime of the loan for the mortgage.
3rd, finally, subtract $90,000 to find out how much interest she paid in total.
4th, how much would Jackie have paid for the lifetime of the loan if her monthly payments were $527.16 (if she had not filed bankruptcy)? Remember, this is the monthly payment, so you don't have to use the formula, just multiply it by 300 months to find the cost of the lifetime loan.
5th, subtract $90,000 from the answer you got in step 4. That is how much interest Jackie would have paid if the monthly loan payments were smaller.
Finally, what is the difference between the interest you found in step 3 and step 5?
a.
$49,200.00
b.
$87,201.20
c.
$68,148.00
d.
$56,809.00
Please select the best answer from the choices provided.
The difference between the interest paid with the minimum monthly payment and the interest paid with the $527.16 monthly payment is $83,421.
What is the interest?
Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.
First, we need to calculate the monthly payment at a 10% interest rate for 25 years:
PV = 90,000
i = 0.10/12
n = 25*12 = 300
Using the formula for the monthly payment of a mortgage loan, we get:
[tex]P = i PV / (1 - (1 + i)^{(-n)})[/tex]
= 805.23
So, if Jackie paid the minimum monthly payment, she would pay $805.23 per month. The total amount paid over the lifetime of the loan would be:
Total amount paid = P * n = 805.23 * 300 = $241,569
The amount of interest paid would be:
Interest paid = Total amount paid - PV = 241,569 - 90,000 = $151,569
If Jackie had made payments of $527.16 per month, the total amount paid over the lifetime of the loan would be:
Total amount paid = 527.16 * 300 = $158,148
The amount of interest paid would be:
Interest paid = Total amount paid - PV = 158,148 - 90,000 = $68,148
Therefore, the difference between the interest paid with the minimum monthly payment and the interest paid with the $527.16 monthly payment is: $151,569 - $68,148 = $83,421
