Step-by-step explanation:
the x coordanate length is 9, because | -4-5 | = 9
and the y coordanate is 13 becasue | -7 - 6 | = 13
Then you do [tex]a^{2}+b^{2} = c^{2}[/tex] which equals 5√10 or approximately 15.81139 which rounds to 15.81

The next term in a sequence Comes from adding the
previous two terms. Find the missing terms below.
2,
,9
, 25,
66
Answers
Answer:
Step-by-step explanation:
Each new term is the sum of the two preceding terms. Given 2, 9, etc., we see that a number between 2 and 9 is missing; call it x. Then 2 + x must equal 9, and so x = 7, and so the first three terms are 2, 7, 9. Repeating the process, we add 7 and 9, obtaining 16; thus the first four terms are 2, 7, 9, 16. Continuing this pattern, we add 9 and 16 to obtain the fifth term, which is 25: 2, 7, 9, 16, 25. And so on.

Which is the graph of the linear inequality y < 3x + 1?
Answers
Answer:
Step-by-step explanation:
The graph for the inequality is attached with the answer.
We have a linear inequality -
y < 3x + 1
We have to plot the graph of this linear inequality.
What is an Inequality?An inequality in mathematics compares two values or expressions, showing if one is less than, greater than, or simply not equal to another value.
According to the question, we have -
y < 3x + 1
Now, in order to plot the graph for this inequality, let -
y = 3x + 1
Plot the line for the above equation. Remember to plot the graph in the form of dashed line since the inequality is strict inequality.
Consider the point (0, 0) -
Solve the inequality for the point (0, 0), we get -
0 < 3 x 0 + 1
0 < 1
Which is true.
Hence, shade the complete area on that side of line where the point
(0, 0) lies.

solve this system of linear equation. separate the x- and y-values with a comma. 15x+4y=-80 5x+5y=1
Answers
Answer:
(x, y) = (-404/55, 83/11)
Step-by-step explanation:
15x + 4y = -80
5x + 5y = 1
Multiplying both side of 2nd equation by 3:
=>
15x + 4y = -80
15x + 15y = 3
Subtracting the 1st equation from 2nd equation:
=>
11y = 83
Dividing both sides by 11 to work out y:
=> y = 83/11
Substituting y back into 2nd equation to work out x:
=> 5x + 5(83/11) = 1
=> 5x + 415/11 = 1
=> 5x = 1 - 415/11
=> 5x = -404/11
=> x = (-404/11)/5
=> x = -404/55
=> (x, y) = (-404/55, 83/11)

A retail store sells two types of shoes, sneakers, and sandals. The store owner pays $8 for the sneakers and $14 for the sandals. The sneakers can be sold for $10 and the sandals can be sold for $17. The owner of the store estimates that she won't sell more than 200 shoes each month, and doesn't plan to invest more than $2,000 on the inventory of the shoes. Let x= the number of sneakers in stock, and y=the number of sandals in stock. 1) Write an inequality that represents the possible amount of shoes she can purchase each month. 2) Next, write an inequality that represents how many sneakers and sandals she has in stock each month. 3) After graphing the constraints, what are the coordinates of the four vertices? Round your answers to the nearest whole number. 4)Write an equation to show the profit she will make on sneakers and sandals. 5)If she sold the number of sneakers and sandals that could maximize her profit, what would her maximum profit be?
Answers
Answer:
(1)[tex]x+y\leq 200[/tex]
[tex]x>0, y> 0[/tex]
(2)[tex]8x+14y\leq 2000[/tex]
(3)From the graph, the coordinates of the four vertices are:
(0,143)(0,0)(133, 67)(200,0)(4)Profit Function: P(x,y)=2x+3y
(5)Maximum profit =$467
Step-by-step explanation:
Let the number of sneakers in stock =x
Let the number of sandals in stock =y
(1)The owner of the store estimates that she won't sell more than 200 shoes each month. Therefore, an inequality that represents the possible amount of shoes she can purchase each month is:
[tex]x+y\leq 200[/tex]
[tex]x>0, y> 0[/tex]
(2)She does not plan to invest more than $2,000 on the inventory of the shoes.
The store owner pays $8 for the sneakers and $14 for the sandals.
Therefore, an inequality that represents how many sneakers and sandals she has in stock each month is:
[tex]8x+14y\leq 2000[/tex]
(3)From the graph, the coordinates of the four vertices are:
(0,143)(0,0)(133, 67)(200,0)(4)The sneakers can be sold for $10 and the sandals can be sold for $17.
Profit on one sneaker =$10-8=$2
Profit on one sandal =$17-14=$3
Profit Function: P(x,y)=2x+3y
(5)
At (0,143), Profit =2x+3y=2(0)+3(143)=$429
At (0,0), Profit =2x+3y=2(0)+3(0)=$0
At (133, 67), Profit =2x+3y=2(133)+3(67)=$467
At (200,0), , Profit =2x+3y=2(200)+3(0)=$400
Her maximum profit will be $467 when she sells 133 sneakers and 67 sandals.
A system of linear equations is shown below, where A and B are real numbers. 3x + 4y = A Bx – 6y = 15 What values could A and B be for this system to have no solutions? A = 6, B = –4.5 A = –10, B = –4.5 A = –6, B = –3 A = 10, B = –3
Answers
Answer:A=6 B=-4.5
Step-by-step explanation:
We want to find the values of A and B such that the given system of equations has no solutions. We will find that the values of A and B can be:
B = -4.5
A = 6
When a system of equations has no solutions?
A system of linear equations has no solutions when the lines are parallel (so the lines never do intercept).
Here the system is:
3x + 4y = A
Bx – 6y = 15
Remember that two lines are parallel if and only if they have the same slope and different y-intercept, then let's write both equations in the slope-intercept form:
y = A/4 - (3/4)*x
y = -15/6 + (B/6)*x
So we must have:
B/6 = -3/4
A/4 ≠ -15/6
From the first one we get:
B = (-3/4)*6 = -4.5
From the second one we get:
A ≠ (-15/6)*4 = -10
Then from the given pairs, the only one that causes the system to have no solutions is:
B = -4.5
A = 6

Answer:
y = (1/2)(x) + 1/2
Step-by-step explanation:
The x-intercept is (-1, 0) and the y-intercept appears to be (0, 1/2).
As we go from the x-intercept to the y-intercept, x increases by 1 and y increases by 1/2. Thus, the slope of the line is m = rise / run = 1/2.
Knowing that m = 1/2 and b = (0, 1/2), we can write the equation of this line in slope-intercept form as
y = (1/2)(x) + 1/2

The figure below shows a quadrilateral ABCD. Sides AB and DC are equal and parallel
A student wrote the following sentences to prove that quadrilateral ABCD is a parallelogram
Side AB is parallel to side DC, so the alternate interior angles, angle ABD and angle CDB, are congruent Side AB is equal to side DC, and DB is the side common to triangles ABD and CDB. Therefore, the triangles ABD and
CDB are congruent by SAS postulate. By CPCTC, angles DBC and BDA are congruent and sides AD and BC are congruent. Angle DBC and angle BDA form a pair of vertical angles that are congruent. Therefore, AD is
parallel and equal to BC Quadrilateral ABCD is a parallelogram because its opposite sides are equal and parallel
Which statement best describes a flaw in the students proof?
O Triangles ABD and BCD are congruent by the SSS postulate instead of the SAS postulate.
Triangles ABD and BCD are congruent by the AAS postulate instead of the SAS postulate.

.
Answers
Answer:
10.5
Step-by-step explanation:
Let E be the midpoint of OA and F be the midpoint of OB.
If point O is placed between A and B, then points E and F are placed on different sides from O. The segment OE has length 12÷2=6 cm and segment OF has length 9÷2=4.5 cm. Than EF=6+4.5=10.5 cm.
If point O is placed outside the segment AB, then point B is closer to point O than point A, because OA>OB. Since OE=6 cm and OF=4.5 cm, EF=6-4.5=1.5 cm.
If the order of points is A, O, B, then the midpoints of AO and OB will be separated by half the length of AB: (12 cm + 9 cm)/2 = 10.5 cm.

Carol Byrd gets a student rate of $30.00 a month. There is a $200 deductible; but no coinsurance payment. She
recently received treatment for a covered condition. The bill was $2,050.00. Carol's insurance company provided
payment of 80% of the bill less the deductible.
What was the company's payment?
What was Carol's total cost (ignoring the monthly premium)?
Answers
Answer:
$160
Step-by-step explanation:
100/100 = 100 ÷ 100 = 100% = 1. Multiply a number by the fraction 100/100
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
The company payment is $1440.
Carol's total cost is $610.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Cost of the bill = $2,050
Company payment = 80% of the bill less the deductible
This means,
80/100 x 2,050 = 1640
Company payment.
= 1640 - 200
= $1440
Now,
Carol's total cost.
= 2,050 - 1440
= $610
Thus,
The company payment is $1440.
Carol's total cost is $610.
