Answer:
all real numbers except x = 0
Step-by-step explanation:
The given equation has undefined terms when x=0, so the domain must exclude that value.
The domain of the terms of the equation is "all real numbers except 0."
__
The solution can be found by adding 1/(2x) to both sides and comparing the terms.
9/4 = 8/(2x) +1/(2x)
9/4 = 9/(2x)
4 = 2x . . . . match denominators of the same numerator
2 = x . . . . . the solution to the equation

Find the value of x andy.
90
117
y
x = 63', y = 27
x = 117",
x = 45, y = 45
x = 27", y = 63
Answer: x= 63, y= 27
Step-by-step explanation:
x and angle measure 117 are a linear pair. They sum to 180.
117+x= 180. Subtract 117 from both sides.
x = 63
Looking at the relationship of x and y, the diagram shows that the two together equal 90 degrees. Add the two together and set equal to 90.
63+y= 90. Subtract 63 from both sides.
y = 27
Answer is x= 63° and y = 27°.
Straight Line angle rule:
A straight angle is an angle equal to 180 degrees.
The sum of angles that are formed on a straight line is equal to 180°.
It is called straight because it appears as a straight line.
Here,
x + 117 = 180 (By straight line rule)
x = 180 - 117
x = 63°.
And Given, x + y = 90°.
y = 90° - x
y = 90° - 63°
y = 27°.

1. Is the following question a statistical question? " During which month did your family take a vacation?"
2. What is the statistical variable represented by the following question, and is it categorical or quantitative? "How many TV sets are owned by families?"
Problem 1
Answer: No, it is not a statistical question
Explanation:
This is because the question is directed at a specific family, your family in particular. If the surveyor is only asking one person, then there's no need for statistics since a sample isn't formed.
If the question is posed to many people taking a survey, then it would be statistical in nature. However, no further context or clarification is given, so I'll assume that the question is directed at one person, or one family, only. I think your teacher would say "During which month do families take vacation?" to be more general and involve statistics.
==============================================================
Problem 2
Answer: The statistical variable is the number of tv sets owned, and this variable is quantitative
Explanation:
The variable is what we want to figure out, and it's random in nature. Hence the name "random variable". It takes on nonnegative whole numbers 0,1,2,3,... so we can see the data set is discrete. The term "discrete" in math means that there aren't infinitely many numbers between two values. For example, if we pick 2 and 5, we can see the values 3,4 are between them and that's it. Contrast this with a continuous data set and there are infinitely many real numbers between 2 and 5 (eg: 2.78912 and 3.412)
While it might be tempting to think of a discrete number set as finite, that's not entirely true. We have infinitely many nonnegative whole numbers to work with. Though of course, there's a realistic limit that we arrive to and someone having 277 televisions is completely out of the ordinary, if not impossible.
The data variable "Number of TV sets owned" is not only discrete, but it's also ordinal, interval and ratio data as well. Here's a breakdown of what I mean
Ordinal = The data values 0,1,2,3,... can be ordered and it makes sense to do so. Usually the order is from smallest to largest.Interval = Gaps between any two values make sense. So going back to 2 and 5, the gap here is 3. Meaning that if family A has 2 tvs and family B has 5 tvs, then we can say that family B has 3 more tvs compared to family A. Such a statement is valid which means interval data applies.Ratio = Not only can we subtract, but we can also divide. If family A has 2 tvs and family B has 6 tvs, then we can see that the second family has 6/2 = 3 times as many televisions compared to the first family. Again, you have to ask if such a statement makes sense for this type of data to apply.Since we have many terms apply to this, it sometimes helps to pick just one and try to have it describe the others implicitly. So we go for ratio data since that encapsulates interval and ordinal data types as well. If something is ratio, then automatically it must be ordinal and interval. Division depends on the numbers being well ordered, and that gaps between values make sense and are consistent.
To recap, the data type is quantitative, discrete, and we have a ratio scale.
The variable "number of tv sets owned" is not categorical since the choices to pick from 0,1,2,3,... aren't names; instead they are numbers in which we can perform math operations on and have it make sense. So that's why we go for quantitative data instead of categorical. If it asked "what brand of TV are owned by families?", then the categories of the various brand names would be the answer choices, and lead to categorical data.
Side note: categorical data is always qualitative

Write a paragraph that addresses one of the following questions:
1. How do you find the area of composite figures?
2. How do you find the surface area of a figure made up of cubes and prisms?
3. How do you find the volume of a figure made of cubes and prisms?
1.) How do you find the area of composite figures?
-A composite figure is made up of simple geometric shapes. To find the area of a composite figure or other irregular-shaped figure, divide it into simple, non overlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure.
2.)How do you find the surface area of a figure made up of cubes and prisms?
-The surface area is the area that describes the material that will be used to cover a geometric solid. When we determine the surface areas of a geometric solid we take the sum of the area for each geometric form within the solid.
3.)3. How do you find the volume of a figure made of cubes and prisms?
-To find the volume of a rectangular prism, we multiply the length of the prism by the width ... Practice set 2: Finding volume with unit cubes.
What is an equation of the line that passes through the points (0, 3) and (5, -3)?
Answer (assuming it can be in slope-intercept form):
[tex]y = -\frac{6}{5} x+3[/tex]
Step-by-step explanation:
1) First, use the slope formula [tex]m =\frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope of the line. Substitute the x and y values of the given points into the formula and solve:
[tex]m =\frac{(-3)-(3)}{(5)-(0)} \\m = \frac{-3-3}{5-0}\\m = \frac{-6}{5}[/tex]
So, the slope is [tex]-\frac{6}{5}[/tex].
2) Now, use the slope-intercept formula [tex]y = mx + b[/tex] to write the equation of the line in slope-intercept form. All you need to do is substitute real values for the [tex]m[/tex] and [tex]b[/tex] in the formula.
Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{6}{5}[/tex] for it. Since [tex]b[/tex] represents the y-intercept, substitute 3 for it. (Remember, the y-intercept is the point at which the line hits the y-axis. All points on the y-axis have an x-value of 0. Notice how the given point (0,3) has an x-value, too, so it must be the line's y-intercept.) This gives the following equation and answer:
[tex]y = -\frac{6}{5} x+3[/tex]

How do you solve this equation? 2 1/2 - 3/4
Answer:
1 3/4
Step-by-step explanation:
you have to convert the mixed numbers into improper fractions first
2 1/2 turns into 5/2
then you make the denominators the same
5/2 turn into 10/4
then you subtract
10/4 - 3/4 = 7/4
then you turn it into a mixed number
7/4 turns into 1 3/4

The solution of the proportion for the value of q will be 9 / 2.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is 2 / 3 = 3 / q. The expression will be solved as:-
2 / 3 = 3 / q
q = ( 3 x 3 ) / 2
q = 9 / 2
Therefore, the solution of the proportion for the value of q will be 9 / 2.
