A function is a set of ordered pairs (x,y) where for each x value there is only one corresponding y value, and the relation between x and y is such that for any x value there is a unique y value.

One way to determine if a set of ordered pairs is a function is to use the vertical line test. This test involves drawing a vertical line on the coordinate plane and seeing if it intersects the graph of the ordered pairs at more than one point. If a vertical line intersects the graph of the ordered pairs at more than one point, then the set of ordered pairs is not a function. If a vertical line intersects the graph of the ordered pairs at only one point, then the set of ordered pairs is a function.

Another way to determine if a set of ordered pairs is a function is to use the rule of correspondence. If every first element of the ordered pair corresponds to one and only one second element, then the set of ordered pairs is a function, otherwise is not.

Additionally, you can also use algebraic methods like the definition of a function, where a function is a relation from a set A to a set B, such that for each element in A there is exactly one element in B.

For example, the set of ordered pairs {(1,2), (2,4), (3,6)} is a function because for each x-value (1,2,3) there is only one corresponding y-value (2,4,6) and this is unique.

In contrast, the set of ordered pairs {(1,2), (2,4), (3,6), (1,3)} is not a function because for x = 1 there are two different y values, 2 and 3.

It's important to remember that it's not enough to just check a few ordered pairs, you need to check all of them.

The points on the graph of f(x) = log9x are (20, 4.5), (11/9, 0.087183), (2439, 3.168910), (181, 2.55231), and (2, 1).

The points on the graph of f(x) = log9x can be calculated by substituting the given values of x in the equation. For example,

f(-1/81) = log9(-1/81) = log9(-1) - log9(81) = undefined

f(20) = log9(20) = log9(2*2*2*5) = log9(2) + log9(2) + log9(2) + log9(5) = 1 + 1 + 1 + 1.5 = 4.5

f(11/9) = log9(11/9) = log9(11) - log9(9) = 1.041393 - 0.954210 = 0.087183

f(-13) = log9(-13) = log9(-1) - log9(13) = undefined

f(2439) = log9(2439) = log9(3*13*37) = log9(3) + log9(13) + log9(37) = 0.477121 + 1.11394 + 1.579789 = 3.168910

f(181) = log9(181) = log9(3*3*7*7) = log9(3) + log9(3) + log9(7) + log9(7) = 0.477121 + 0.477121 + 0.84509 + 0.84509 = 2.55231

f(2) = log9(2) = log9(2) = 1

Hence, the points on the graph of f(x) = log9x are (20, 4.5), (11/9, 0.087183), (2439, 3.168910), (181, 2.55231), and (2, 1).

Horizontal dilation- If x is replaced by x/A in a formula and A>1, then the effect on the graph is to expand it by a factor of A in the x-direction (away from the y-axis).

If A is between 0 and 1 then the effect on the graph is to contract by a factor of 1/A (towards the y-axis).

We use the word "dilate'' to mean expand or contract.

For example, replacing x by x/0.5=x/(1/2)=2x has the effect of contracting toward the y-axis by a factor of 2.

If A is negative, we dilate by a factor of |A| and then flip about the y-axis. Thus, replacing x by −x has the effect of taking the mirror image of the graph with respect to the y-axis.

For example, the function y=√-x, which has domain {x∈R∣x≤0}, is obtained by taking the graph of √-x and flipping it around the y-axis into the second quadrant.

There are √131 lies between the two whole numbers 11 and 12.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.

The square root of 131 is approximately 11.445 It lies between the two numbers 11 and 12, specifically, it is greater than 11 and less than 12.

We know that the square root of a number is the value that, when multiplied by itself, gives that number.

For example, the square root of 121 (which is 11) is 11 because 11 x 11 = 121.

In the same way, the square root of 131 is the number that, when multiplied by itself, will give 131.

Since 131 is a prime number and it is not a perfect square, the square root of 131 cannot be a whole number, it should be decimal and it lies between 11 and 12.

Longitudes: The vertical lines running north-south, join the two poles. They are called the meridians of longitude. They are spaced farthest apart at the equator and converge at a point at each pole.

Horizontal lines called latitudes are used to measure distances north or south of the equator. Vertical lines known as longitudes are used to determine the west or east of the meridian in Greenwich, England. Latitude and longitude work together to help cartographers, geographers, and others find specific locations on the globe.

What is the uses of latitude?

Any location's distance from the equator may be determined using its latitude, which is based on its degree. We can locate any point on Earth using longitude and latitude. The GPS or Global Positioning System uses these coordinates.

The grid system that enables us to locate absolute or precise places on the surface of the Earth is made up of latitude and longitude. Latitude and longitude can be used to pinpoint certain locations. Landmark identification also benefits from knowledge of latitude and longitude.

We can start by using the following equation to determine the number of yards of red fabric r she will need for each costume:

1 + r = y (y represents the total number of yards of fabric for each costume)

We know that the total number of yards for all the costumes is 8 and there are 5 costumes, so we can use this information to set up another equation:

5y = 8 (y represents the total number of yards of fabric for each costume)

Now we can substitute the first equation into the second equation to get:

5(1 + r) = 8

Expanding the left side of the equation:

5 + 5r = 8

Subtracting 5 from both sides:

5r = 3

Dividing both sides by 5:

r = 3/5

So, Mrs. Byers will need 3/5 yards of red fabric for each costume.

To find the m<MKL given that MK bisects <JKL proves that; m<MKL is 38^o.

A straight line that splits a measure of an angle into two equal parts is termed as an angle bisector. So that the measure of the two parts are the same.

The lengths in the scale drawing are smaller than the corresponding lengths in the original figure.

When the scale factor is less than 1, the image of a shape will be reduced in size compared to the original shape. This means that all dimensions of the shape will be scaled down by the same factor. For example, if a shape is scaled down by a factor of 0.5, its length, width, and height will all be half the size of the original shape. Additionally, the area and volume of the image shape will be scaled down by the square and cube of the scale factor respectively.

In other words, when the scale factor is between 0 and 1 it will be a reduction and if it's greater than 1 it will be an enlargement.

As can be seen from the question, the scale factor is less than one as it is 1 / 3. This means that the lengths on the scale drawing would be smaller than the lengths on the original drawing.

All possible solutions for inequality are (-∞,-7)U(-7, ∞).

What is inequality?

In mathematics, a relationship between two expressions or values that are not equal to each other is called 'inequality. ' So, a lack of balance results in inequality.

The inequality q/7 > -1 is a mathematical statement that compares the value of q/7 to -1.

To solve the inequality, we can start by isolating q on one side of the inequality.

To do this, we need to multiply both sides of the inequality by 7:

q/7 * 7 > -1 * 7

q > -7

Now we have the inequality q > -7, this inequality states that q is greater than -7.

To find all possible solutions for the inequality, we can use interval notation. The interval notation for the solution of this inequality is (-infinity,-7)U(-7, infinity)

It means all real numbers except -7, the solution set is an open interval.

Alternatively, we can also graph the solution set of the inequality on a number line, shading the region that represents the solution. The shaded region will be all the points to the right of -7 on the number line.

Hence, all possible solutions for inequality are (-∞,-7)U(-7, ∞).
