The two angles are alternate external, because they are on the external side of the parallel lines and on alternate sides of the transversal one. This means that they are congruent. So we can find the value of x by making their expressions equal and solving for x.

Suppose Julia spends $932 on her credit card. Calculate the amount of interest she would owe in one month if she does NOT pay off her balance in full by the due date. Julia's APR is 16.99%. Estimate the interest charges using the monthly periodic rate
Answers
Answer:
The amount of interest she would owe in one month if she does not pay off her balance in full by the due date is $13.2
Explanation:
Given that Julia's APR is 16.99%
Suppose she spends $932 on her credit card, the amount of interest she would owe in a year is 16.99% of $932, this amounts to
0.1699 * 932
= $158.3468
To know the interest in a month, we divide the last result by 12
158.3468/12
= $13.196
This is approximately $13.2

Explanation:
A relation is a function if every value of x is related to just one value of y.
So, number 6 is not a function because -4 is related to 9 and -4 is also related to 0.
Number 7 is a function because every value of x (first coordinate) is related to one value of y (second coordinate).
In the same way, we can say that number 8 is also a function and number 9 is not a function because number 7 is related to 0, -5, -8, 4, and 3.
Finally, for the graph of numbers 10, 11, and 12 we need to identify the coordinates of every point.
So, number 10 is equivalent to:
{(-7, -1), (-2, -7), (0, 2), (4, 2), (6,6)}
It means that number 10 is a function
For number 11, we get:
{(-5, -4), (-3, 5), (2, -1), (2

The perimeter of the figure is the sum of the lengths of its sides. Find the missing side lengths to calculate the perimeter of the figure.
The length of then missing horizontal side is 6yd because it must add up to 8yd with the 2yd segment.
The length of the missing vertical side is 4yd because it must add up to 7yd with the 3yd segment.
Then, the perimeter of the figure is:

If the lines /1 and /2 are parallel, what must be value of y?
Answers
ANSWER
y = 130 degrees
STEP-BY-STEP EXPLANATION
Key points to note in the provided figure
Alternate exterior angles are equal
The sum of supplementary angles is 180 degrees
From the figure given, angle y and angle 5x are alternate exterior angles
Since alternate exterior angles are equal. Hence, angle y = angle 5x
y = 5x
Also, angle (2x - 2) and y are supplementary angles
Recall, the sum of supplementary angles is 180 degrees
Hence, we have
y + (2x - 2) = 180
Note, y = 5x
substitute y = 5x into the above equation
5x + (2x - 2) = 180
Open the parenthesis
5x + 2x - 2 = 180
Collect the like terms
5x + 2x - 2 = 180
7x - 2 = 180
Add 2 to both sides of the equation
7x - 2 + 2 = 180 + 2
7x = 182
Divide both sides by 7
7x/7 = 182/7
x = 26 degrees
Since we have gotten the value of x = 26 degrees. Hence, we can now find the value of y
Recall, y = 5x
y = 5(26)
y = 130 degrees
Write an equation of the line in slope intercept form that passes through the given point and is perpendicular to the given line.(-2,4) , y = 2x + 9
Answers
We are given the point (-2,4) and the line y=2x+9. We want the equation of the line that passes through the given point and that is perpendicular to the given line.
To do so, we will use the following equation of a line
[tex]y\text{ -a = m\lparen x -b\rparen}[/tex]in this equation, m is the slope of the line and (a,b) is a point in the line. In our case, we are given that (-2,4) is in the line. That is, a=-2 and b=4. So our equation becomes
[tex]y\text{ -4=m\lparen x -\lparen-2\rparen\rparen}[/tex]or equivalently
[tex]y\text{ -4}=m(x\text{ +2\rparen}[/tex]now, we only need to find the value of m. To do so, we use the given line and the fact that the product of the slopes of perpendicular lines is -1.
The given line (2x+9) has a slope of 2. So, we have the following equation
[tex]m\cdot2=\text{ -1}[/tex]so if we divide both sides by 2, we get that
[tex]m=\text{ -}\frac{1}{2}[/tex]So the equation we are looking for becomes
[tex]y\text{ -4 }=\text{ -}\frac{1}{2}(x\text{ +2\rparen}[/tex]We want this equation in the slope intercept form. So we operate to find y in this equation. So first, we distribute on the right hand side. We get
[tex]y\text{ -4}=\text{ -}\frac{1}{2}x\text{ -}\frac{2}{2}=\text{ -}\frac{1}{2}x\text{ -1}[/tex]now we add 4 on both sides, so we get
[tex]y=\text{ -}\frac{1}{2}x\text{ -1+4= -}\frac{1}{2}x+3[/tex]we can check that if x= -2 we get
[tex]y=\text{ -}\frac{1}{2}(\text{ -2\rparen+3=1+3=4}[/tex]which confirms that the point (-2,4) is on the line

A store has clearance items that have been marked down by 45%. They are having a sale, advertising anadditional 50% off clearance items. What percent of the original price do you end up paying?%Give your answer accurate to at least one decimal place.
Answers
We have clearance items that have two discounts applied to its price.
We can use a $1 item to find the final discount.
If we apply a 45% mark down, we will obtain a price of:
[tex]1-1*0.45=0.55[/tex]The discounted price is $0.55.
To this price we apply a 50% off. This can be expressed as:
[tex]0.55(1-0.5)=0.55*0.5=0.275[/tex]This is the final price.
We can calculate the percentage of the original price as:
