For 4 years, Deirdre paid $2 in dues.

Deirdre paid each year for three years = 3 × 10 = 30.

Let's consider x as the number of years,

As Deirdre paid $2 for x years the value she paid will be 2x,

Deirdre paid = $2x (in x years)

Deirdre has paid $10 for three years each, a total of $38 in dues. So the final equation will be,

38 = 30 + 2x

38 - 30 = 2x

8 = 2x

x = 4

Thus, Deirdre has paid $2 in dues for 4 years.

I don't see any statements either.

anyway, the only thing that can be said about the 2 lines is that they are crossing each other at one point.

the lines are not parallel, they are not perpendicular (90° to each other), they are not identical.

nothing can be said about a specific point on the line of intercepts with the x- and y-axis.

they are also not parallel and not perpendicular to any of the x- or y-axis.

Answer: See explanation

Step-by-step explanation:

For questions 1 - 4, it's asking you to plug in numbers into the original functions.

1. f(-2): You would plug -2 into f(x) = 2x^2 - 3x, getting

2(-2)^2 - 3(-2)

2(4) - (-6)

8 + 6 = 14

f(-2) = 14

2. f(x) - g(x): You're basically just subtracting the two functions

(2x^2 - 3x) - (2 - 5x)

2x^2 - 3x - 2 + 5x

Combine like terms

2x^2 + 2x - 2

3. You're multiplying them so (2x^2 - 3x)(2 - 5x)

4. f(g(x)): It's like f(-2), but instead of -2, you plug in the function of g(x)

So in 2x^2 - 3x, x would equal 2 - 5x:

2(2 - 5x)^2 - 3(2 - 5x)

And then simplify that.

For questions 5 - 6, it's asking for shifting from the parent function. Parent function is always f(x) or g(x) or whatever variable it is.

5. f(x - 8) + 9: The 9 is the y value shift, meaning the parent function is shifted up 9 units. For -8, think of what x needs to be for (x - 8) to be 0. If that number is positive, function shifts right; if negative, shift left. In this case, x needs to be 8 in order for (x - 8) to be 0. Therefore, f(x) is shifted right 8 units.

6. -3f(x) - 2: From the previous question, we now know that -2 means f(x) is shifted down 2 units. When you have 3f(x), you're multiplying the entire function by 3, so it's called a vertical stretch of 3. The negative means it's reflected over the x-axis since the y value is the opposite of what it used to be.

After using Arithmetic we'll get - Total of her paycheck $250

What is Arithmetic ?

The study of the characteristics of the standard operations on numbers, including addition, subtraction, multiplication, division, exponentiation, and root extraction, constitutes the fundamental subject of arithmetic. Giuseppe Peano, an Italian mathematician, formalised arithmetic in the 19th century with the help of his Peano axioms, which are still crucial to the modern study of mathematical logic. There are only a few artefacts from the early history of mathematics that may have shown how addition and subtraction were first thought of. The best-known of them is the disputedly interpreted Ishango bone from central Africa, which dates from between 20,000 and 18,000 BC.

By considering the climate of the North Pole, Alaska, the change in the Temperature, is 13°F and 14 °F on the 1st and last day of the month respectively.

Alaska experiences an average low temperature of 9°F (-13°C) and an average high temperature of 22°F (-5°C) in January. You should be able to see the little sun that is shining (just for 5 to 6 hours per day on average) since it is clear for roughly 60% of the days.

Alaska's typical February temperature ranges from a low of 12°F (-11°C) to a high of 26°F (-3°C). There is a little bit more cloud cover (approximately 50% of days) and roughly 8 hours of sunlight per day, which both contribute to this rise in temperatures.

Change in Temperature:

On 1st day of January , the Change in temperature = Highest Temperature - lowest temperature = 22°F - 9°F = 13°F

On the 1st day of February, and the last day of January, the Change in temperature = Highest Temperature -  lowest temperature = 26°F -  12°F = 14 °F.

Usually if it a triangle with 2 angles and an x

you will add the 2 angles and rearrange to give the answer

Step-by-step explanation:

Hope this helps!!!

Answer:

A right triangle has one angle measuring 90 degrees. The side opposite this angle is known as the hypotenuse (another name for the longest side). The length of the hypotenuse can be discovered using Pythagoras's theorem, but to discover the other two sides, sine and cosine must be used. These are trigonometric functions of an angle.

In the diagram below, one of the angles is represented by the Greek letter θ. (pronounced "the - ta"). Side a is known as the "opposite" side and side b is called the "adjacent" side because of their positions relative to the angle θ.

The vertical lines "||" around the words below mean "length of."

So sine, cosine and tangent are defined as follows:

Step-by-step explanation:

So sine, cosine and tangent are defined as follows:

sine θ = |opposite side| / |hypotenuse|

cosine θ = |adjacent side| / |hypotenuse|

The sequence's numbers are all multiples of 30. Every number can be divided by 30.

If two integers are divided equally, leaving no remainder, then we say that one integer divides the other (we sometimes say, "with no remainder," but that is not technically correct). Mathematicians express this more explicitly as follows: If a and b are integers (with a not zero), then a divides b if c is an integer such that b = ac. Sequence: 1 51, 2 52,....., n 5n,....n 5n=n(n 4 1)=n(n1)(n1)(n+1)(n 2 +1)

At n=1, n 5, n=0, n=1, 2, 3, etc. Not attainable

Atn=2,n 5 −n=30 ∴ The sequence's numbers are all multiples of 30. Every number can be divided by 30.

To answer this question, first we need to properly understand the definition of median and mean, and also understand what it means to be "roughly symmetrical".

Let's start with the definition of median.

"the median is the value separating the higher half from the lower half of a data sample"

If we have an odd amount of elements in our dataset, the median is literally the middle element of our set.

Example:

We have four elements below 3, and four elements above 3, therefore, the median of this dataset is 3.

If we have an even amount of elements, the median is the mean between the two elements in the middle.

Example:

The elements in the middle are 1 and 2. This means our median is

1.5.

Now, let's understand the mean.

By definition, The Arithmetic Mean is the average of the numbers: a calculated "central" value of a set of numbers, given by the sum of all elements divided by the amount of elements.

Examples:

Now that we know what mean and median exactly are, let's try to understand what it means to be "roughly symmetrical".

When talking about histograms, Close to symmetric means the data are roughly the same in height and location on either side of the center of the histogram.

As the histogram gets closer to symmetric, the mean approaches the middle values, to be more specific, If the histogram is close to symmetric, then the mean and median are close to each other.

Since the statement says "roughly symmetrical" this is the only thing we can claim. If we have more values to the right in our roughly symmetrical distribution, the mean will be a little bit bigger than then median, and if we have more values to the left in our roughly symmetrical distribution, the mean will be a little bit smaller than then median.

Natural number: No, because when you divide -202/45 you do not get a integer.

Integer: No, for the reason given before.

Whole number: No, for the reason given before (it is not an integer)

Real number: Yes, because real numbers include negative fractions.

Irrational number: No, because you can write the number as a fraction of two integers.

You would find the number -202/45 in the set of the real numbers.

The measure of x is found as 22 for the given vertically opposite angles.

For the given question;

5x + 4 = 114 (As both lines intersecting and vertical angles are formed).

Solving the equation;

5x = 114 - 4

5x = 110

x = 22

Thus, the measure of x is found as 22.
