Your answer would be the second option, (-4,5).
We can find this by substituting in each point into the equation y < |x - 3| and seeing if it is true.
For the first one you get 1 < |2 - 1|. |2 - 1| = |-1| = 1, and 1 cannot be less than itself, so this is false.
For the second one you get 5 < |-4 - 3|. |-4 - 3| = |-7| = 7, and 5 is indeed less than 7, so this is correct.
I hope this helps!

BC=
im not sure on how i am supposed to do this
Answer:
BC=15.01
Step-by-step explanation:
Line segment BC can also be represented by '?'. To solve for BC, find the value of '?'
Use the tangent ratio:
[tex]tangentX=\frac{opposite}{adjacent}[/tex]
Because you need the value opposite the given angle and you are given the length of the side adjacent the given angle (hypotenuse does not count as the adjacent side, EVER (btw)). Let 65° be X and let x replace'?'.Insert the appropriate values:
[tex]tan65=\frac{x}{7}[/tex]
Solve by isolating x. Multiply 7 to both sides:
[tex]7*(tan65)=7*(\frac{x}{7})\\\\7*tan65=x\\\\x=7*tan65[/tex]
Insert this equation into a calculator:
[tex]x=15.0115...[/tex]
Round to the nearest hundredth:
[tex]x=15.01[/tex]
So, BC is 15.01
Finito.

Mrs. Henry bought books during the summer. She bought 5 books for $12.00, 6 books for $10.00, and 4 books for $8.00. What is the average (mean) amount she spent for each book?Answer options with 5 optionsA.$4.00 per bookB.$3.25 per bookC.$3.00 per bookD.$2.75 per bookE.$2.00 per book
Answer: $60.00 (5 books), $60.00 (6 books), $32.00 (4 books) is the data set. The answer, when used in a calculator, is 3.3777777777. From this result, I would say B or $3.25 per book.
The correct answer is option B) $2.75.
How to find mean?
The mean formula is given as the average of all the observations. It is expressed as Mean = {Sum of Observation} ÷ {Total numbers of Observations}.
By applying the formula
= 40/15
≅ 2.75
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words, it is the sum divided by the count.

The second step is
The answer is
Answer: 1
Step-by-step explanation:
(16+12x)=28
Since 4is a common factor in both terms we take out 4
4(4+3x)=28
Now take 4 to the other side
4+3x = 28/4 = 7
Similarly
3x = 7-4 =3
We end up with 3x=3
So X = 1

Write the first four terms of the recursive sequence: If a1=8 and an=a(n-1) -6
Is the recursive sequence arithmetic or geometric? Explain.
Answer:
8, 2, -4, -10.
Step-by-step explanation:
Each term (except the first one) is obtained by subtracting 6 from the previous one - that is what an = a(n -1) -6 means.
First term = a1 = 8 , so the second term = 8-6 = 2.
The first 4 terms are 8, 2, -4, -10.
This is an arithmetic sequence as there is a common difference of -6.

1. Triangle JKL is dilated by a scale factor of 1.5 with
the origin as the center of dilation. Look at each
ordered pair. Does the ordered pair represent a
vertex of the image?
Select Yes or No for A-C.
A. (-3, -4.5) O Yes No
B. (1.5,-6) O Yes O No
C. (3,0) o Yes O No
Answer:
A. yes
B. yes
C. no
Step-by-step explanation:
The coordinates of each point are (x, y).
J (-2, -3)
K (0, 2)
L (1, -4)
After being scaled by 1.5 about the origin, the coordinates are (1.5x, 1.5y).
J (-3, -4.5)
K (0, 3)
L (1.5, -6)
Examine the system of equations. y = 2x – 3, y = –3 Which statement about the system of linear equations is true?
(A) The lines have different slopes.
(B) There is no solution to the system.
(C) The lines have the same slope, but different y-intercepts.
(D) The solution is (–3, –9).
Answer: A
Step-by-step explanation:
For a system of equations to have no real solution, the lines of the equations must be parallel to each other. The correct option is A the lines have different slopes.
What is the System of equations?Inconsistent System
For a system of equations to have no real solution, the lines of the equations must be parallel to each other.
Consistent System;
For a system of the equation to be a Dependent Consistent System, the system should have multiple solutions for which the lines of the equation must be coinciding.
For a system of the equation to be an Independent Consistent System, the system should have one unique solution for which the lines of the equation must intersect at a particular.
If the two of the given system of equations are plotted on the graph, y = 2x – 3, y = –3
Then it can be seen that the two lines have different slopes. Therefore, the correct option is A.

Craig bought 96 rolls or toilet paper for 48 dollars. What is the cost of a single
roll of toilet paper?
dollars
Check
Explain
HELP ME PLEASE
Final answer:
The cost of a single roll of toilet paper is $0.50, calculated by dividing the total cost of $48 by the number of rolls which is 96.
Explanation:
To find the cost of a single roll of toilet paper, we need to divide the total cost by the number of rolls. Craig bought 96 rolls of toilet paper for $48.
To calculate the cost per roll, we use the formula:
Cost per roll = Total cost / Number of rolls
So,
Cost per roll = $48 / 96 rolls
Cost per roll = $0.50 per roll
Therefore, the cost of a single roll of toilet paper is $0.50.
Can someone please find the volume of this shape and show work for how you did it??
Answer:
[tex]221.4m^{3}[/tex]
Step-by-step explanation:
To work out the volume of this shape you will first need to work out the area of the triangle. To work out the area of the triangle you would multiply the base of 12 by the height of 4.1, which gives you 49.2. You would then need to divide 49.2 by 2, which gives you 24.6. This is because the formula for the area of a triangle is the same as that of a square, however a triangle is half of a square with the same length and width. To work out the volume you would multiply the area of the triangle, which is 24.6 by the height of 9, which gives you 221.4[tex]m^{3}[/tex]
1) Multiply 12 by 4.1.
[tex]12*4.1=49.2[/tex]
2) Divide 49.2 by 2.
[tex]49.2/2=24.6[/tex]
3) Multiply 24.6 by 9.
[tex]24.6*9=221.4m^{3}[/tex]

Write the equation of the line that is parallel to the line and through the given point y=-2x+1 point (0,5)
Answer:
y = -2x+5
Step-by-step explanation:
y = -2x+1 is in the form y= mx+b where m is the slope and b is the y intercept
-2 is the slope
Parallel lines have the same slope so our new line will have the same slope
y = -2x+b
The point given is the y intercept (value when x is zero)
b = 5
y = -2x+5

ms knight wants to throw a pizza party for all the 7th graders.in a random sample 13 ou of 20 7th graders preferred peperonie pizza the other 7 preferred cheeze. Based on the data out of 400 total 7th graders aproaxmently how many prefer peperoni
To estimate how many out of 400 seventh graders prefer pepperoni based on the sample, a proportion is used, resulting in approximately 260 students preferring pepperoni pizza.
Explanation:Ms. Knight wants to throw a pizza party for the seventh graders, and in a random sample, 13 out of 20 seventh graders preferred pepperoni pizza. To estimate how many out of 400 seventh graders would prefer pepperoni, we use a proportion. The proportion of students who prefer pepperoni in the sample is 13/20. To find the number who would prefer pepperoni out of 400, we set up a cross-multiplication:
13/20 = x/400Solving this equation for x (the number of 7th graders who prefer pepperoni out of 400) gives us:
20x = 13 * 40020x = 5200x = 5200 / 20x = 260So, approximately 260 seventh graders would prefer pepperoni pizza out of 400 based on the sample data.
