Answer:
First and fourth statements are correct
Step-by-step explanation:
The function is [tex]|x+3|<5[/tex] where the domain is [tex]-8<x<2[/tex]
[tex]|-2+3|=1<5[/tex]
The first statement is correct.
[tex]|1+3|=4<5[/tex]
Substituting a value into the inequality from the solution set, such as 1, will create a false statement. This is wrong as it creates a true statement.
[tex]|4+3|=7\nless 5[/tex]
Substituting a value into the inequality not from the solution set, such as 4, will create a true statement. This is wrong as a value which is not from the solution set will create a false statement.
[tex]|6+3|=9\nless 5[/tex]
Substituting a value into the inequality not from the solution set, such as 6, will create a false statement. This is correct.
[tex]|10+3|=13\nless 5[/tex]
Substituting any value into the inequality will create a true statement. This is wrong as the value of x must be in the solution set.
Answer:
1.) Substituting a value into the inequality from the solution set, such as –2, will create a true statement.
4.) Substituting a value into the inequality not from the solution set, such as 6, will create a false statement.

The expression [tex]-2\vec C+6\vec D[/tex] in the ordered pair notation is (16,-16).
The vector components of a vector are represented as the ordered pair of its x and y components.
For example, if a vector has x - component 'a' and y- component 'b' , then the ordered pair notation for the vector is (a, b), where the vector is [tex]a \vec i+b \vec j[/tex].
Now the vector C has its x- component = -2
y- component of C = -1
Therefore, ordered pair notation of C = (-2, -1)
x- component of D = 2
y-component of D = -3
Therefore, ordered pair notation of D = (2,-3)
So the expression [tex]-2\vec C+6\vec D[/tex] = -2 (-2,-1) +6 (2,-3) = (4,2) + (12, -18)
= (16, -16) in the ordered pair notation.
That is, the vector [tex]\bold {-2\vec C+6\vec D}[/tex] is a vector with x-component 16 and y-component -16.

The rational number equivalent to 1.28 bar over 28 is 1and 28 over 99 that is option 2) is correct
The number that we have been given is 1.28 bar over 28 that is 28 is repeating.
Now we have to convert it into simple fraction.
For we will first denote,
X = 1.28 bar over 28
Multiplying both side by 100 as two digits are being repeated we get,
100X = 128.2828…
Now subtracting it from X on both side s and putting the value of X we get
100X – X = 128.28… - 1.2828….
99X = 127
X =127/99
X = 1 28/99
Hence the rational number equivalent to 1.28 bar over 28 is 1and 28 over 99 that is option 2) is correct

What is linear equation in two variables?A linear equation in two variables is one that is written in the form ax + by + c = 0, where a, b, and c are real numbers as well as the coefficients of x and y, i.e. a and b, are not equal to zero.
For instance, 10x+4y = 3 and -x+5y = 2 are two-variable linear equations.The solution to such an equation is just a pair of values, one is for x and one for y, which also equalizes the 2 sides of an equation.Now, for the given question;
Let us consider that the total attendance in 2012 be 'x'.
And the total attendance in 2014 be 'y'.
Then, the total attendance for 2014 will be twice the attendance in 2012.

is a proper subset different from a regular subset? is an empty set a proper subset? provide an example of a set for your classmates to solve for both a proper subset and an empty set. check and respond to the replies to your examples.
yes proper subset is different from a regular subset. The empty set is a proper subset of every set except for the empty set
A proper subset of a set A is a subset of A that cannot be equal to A. In other words, if B is a proper subset of A, then all elements of B are in A but A contains at least one element that is not in B.
Subset: If A and B are sets and every element of A is also an element of B, then:
A is a subset of B, denoted by A ⊆ B.
or equivalently, B is a superset of A, denoted by B ⊇ A.
Any set is considered to be a subset of itself. No set is a proper subset of itself. The empty set is a subset of every set. The empty set is a proper subset of every set except for the empty set.
For example, A = {1, 2, 3, 4, 5} and B = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.
A = {1, 2, 3} and B = {1, 2, 3}
Here, A is a subset of B, or we can say that B is the superset of A.
Proper Subset: If A is a subset of B, but A is not equal to B (that is, there exists at least one element of B which is not an element of A), then
A is also a proper (or strict) subset of B; this is written as A ⊊ B.
For example A = {1, 2, 3} and B = {1, 2, 3, 4}.
Clearly, A is not equal to B and element {4} belongs to set B but is absent in set A, so we have one element in set B which is not an element of set A. Thus, A can be called a proper subset of B.
Hence, a proper subset of a set A is a subset of A that is not equal to A. In other words, if B is a proper subset of A, then all elements of B are in A but A contains at least one element that is not in B, thus the proper subset may or may not be the same.

The Number of Gallons drained per minute from the pool is; 931.5 gallons drained per minute
What is the constant rate?Constant rate is simply a rate that remains unchanged regardless of change in parameters.
Now, we are told that One hundred three and one half gallons drained in the last 9 minutes from a pool. Thus;
Amount of gallons that drained from pool = 103¹/₂ gallons = 207/2 gallons
Time it took to drain = 9 minutes
Thus;
Number of Gallons drained per minute from the pool = (207/2)/9

We need to solve for x. Our first step is to identify a common denominator. Let's list the multiples of each denominator.
9: 9, 18, 27, 36
12: 12, 24, 36
Our common denominator is 36.
Now, let's cross multiply:
