According to the converse of corresponding angles theorem, the statement that allows Carmen to conclude that lines p and q are parallel is: ∠2 ≅ ∠6.
What is a Transversal?A transversal is a line that crosses two straight lines. For example, line t is a transversal that crosses the lines p and q in the given diagram above.
What are Parallel Lines?Parallel lines are lines that do not meet each other at any point and are of equal distant to each other.
When a transversal intersects two parallel lines, they form angle pairs. One of such angle pairs is, corresponding angles, which are always congruent to each other.
Thus, if corresponding angles are formed and are equal to each other, then the lines they lie on must be parallel lines based on the corresponding angles converse theorem.
Angles 2 and 6 are corresponding angles that are formed by the transversal that intersects lines q and p. If they are congruent angles, then the lines are parallel.
Therefore, Carmen can use the statement, ∠2 ≅ ∠6 to show that lines q and p are parallel.

Latoya opened a savings account and made an intial deposit. After the intial deposit, she added money into the account each week she added the same amount each week with out any withdrawals after the forth week she had $450 by the ninth week she had $825 what was latoya's intial deposit?
Answers
She made an initial deposit that we will call "D", as it is one of the unknowns.
We know that she made a weekly deposit (lets call this amount "w").
After 4 weeks she had $450 in the account balance and this is the sum of the initial deposit and 4 weekly deposits, so we can write:
[tex]D+4w=450[/tex]At the ninth week she had $825, that correspond to the initial deposit and 9 weekly deposits. This can be written as:
[tex]D+9w=825[/tex]We have a system of linear equations that we will solve by elimination: we will substract the first equation from the second and then find w.
[tex]\begin{gathered} (D+9w)-(D+4w)=825-450 \\ 5w=375 \\ w=\frac{375}{5} \\ w=75 \end{gathered}[/tex]Now that we know "w", we can calculate D with any of the two equations:
[tex]\begin{gathered} D+4w=450 \\ D+4\cdot75=450 \\ D+300=450 \\ D=450-300 \\ D=150 \end{gathered}[/tex]Answer: the initial deposit was $150.
#1 - Find the inverse of the function shown. *y = ( 6х + 12)/2
Answers
The given function is expressed as
y = (6x + 12)/2
In order to determine the inverse of the given function, we would substitute x for y and y for x. Then we would solve for y. It becomes
x = (6y + 12)/2
x = 3y + 6
3y = x - 6
y = (x - 6)/3
y = x/3 - 2
The inverse is

YOU HAVE 2 .Please help!! Find the values of x and y.
Answers
The values of x and y will be 100° and 10° when two parallel lines are being cut by a transversal line.
According to the question,
We have a figure where two parallel lines are being cut by a transversal line.
Now, we know that the angles formed on a straight line is 180° and vertically opposite angles are equal.
The sum of consecutive interior angles is 180°.
Now, we will use these three statements in finding the values of x and y.
Now, adding (2x-70)° and (5y)° will give 180° because the angles made are on a straight line.
(2x-70)°+(5y)° = 180°
2x+5y = (180+70)°
2x+5y = 250° .... (1)
Now, (x+30)° will be the interior angle consecutive to 5y° because they are vertically opposite angles.
So, we have:
(x+30)°+5y° = 180°
x+5y = (180-30)°
x+5y = 150°
5y = 150-x
Now, putting this value of 5y in equation 1:
2x+5y = 250
2x+150-x = 250
x+150 = 250
x = (250-150)°
x = 100°
Now, we will find the value of y:
5y = 150-x
5y = 150-100
5y = 50
y = 50/5
y = 10°
(Note that the values of x and y will be in ° because angles are measured in degree.)
Hence, the value of x is 100° and the value of y is 10°.

Assume the standard deviation is $14 and the variable is normally distributed. Round your answers to the nearest hundredth.Minimum: $Maximum: $
Answers
Solution
For this case we have the following random variable:
X= amount spend on average for groceries by one person
And we have the following properties:
mean= 52
sd= 14
The distribution of the variable is normal
We can find the middle 50% using a graph like this one:
We can find two quantiles from the normal distribution that accumulates 25% of the area on each tail of the distribution and we have:
Z= -0.674 and 0.674
Now we can use the z score formula given by:
[tex]z=\frac{x-\mu}{\sigma},x=\mu\pm z\cdot\sigma[/tex]So then we have:
Minimum= 52 - 0.674*14 = 42.56
Minimum= 52 + 0.674*14 = 61.44

The 816 is just two times (Plane ticket back and forth) so it doesn't go into the x. 100 and 95 do as it is one day.

Prove that 3x + y = 7 + y and 3(x + y) = 2 + 3x are perpendicular
Answers
Answer:
Since one line is vertical, and one line is horizontal, the lines are perpendicular.
Step-by-step explanation:
The product of the slopes of perpendicular lines is -1.
We find the slopes of the 2 lines and multiply them together.
If the product equals -1, then the lines are perpendicular.
To find the slopes of the lines, we write each equation in the y = mx + b form, where m is the slope. In other words, we solve each equation for y.
3x + y = 7 + y
Subtract y from both sides.
3x = 7
x = 7/3
This is not the y = mx + b form since there is no y in the equation. A line with equation x = k, where k is a number, is a vertical line that passes through the point (k, 0), and the x-coordinate of all points on the line is k.
3(x + y) = 2 + 3x
3x + 3y = 2 + 3x
Subtract 3x from both sides.
3y = 2
y = 2/3
y = 0x + 2/3
Slope = m = 0
A line with 0 slope is a horizontal line.
Since one line is vertical, and one line is horizontal, the lines are perpendicular.

Set theory, a branch of mathematical logic, studies sets, which are essentially collections of objects.
Despite the fact that every form of object may be turned into a set, set theory is a branch of mathematics that primarily deals with issues that are relevant to mathematics as a whole.
The foundation of set theory is a straightforward binary link between an object o and a set A.
If o is a component (or member) of A, it is expressed as o A. When listing members of a set, commas are used to indicate their separation, or brackets are used to surround a property of those parts.
Since sets are objects, they can be connected by the membership relation.
Given set U = {11,12,13,14,15,16,17,18,19,20}
A = {12,14,16,18,20}
B = {12,15,18}
