(-10, -3)
Step-by-step explanation:
() excludes -10 and -3 so it only includes the numbers in between.
The set builder notation is {x: x ∈ Z⁻, -10 < x < -3} and the set is {-9, -8, -7, -6, -5, -4}
Set-builder notation The set notation consists of symbols like ': - such that', '∈ - belongs to', ' <, >, ≤, ≥', and all these are enclosed in flower braces. The Capital letter that is used in this represents the category or the set to which the given values are related. A variable is used for representing the given set of data values.Set-builder notation is a mathematical notation for describing a set by representing its elements or explaining the properties that its members must satisfy.
It is given the set of numbers that are greater than -10 and less than -3.
Since they are negative integers, so all the required numbers also belong to the same category of numbers.
So, it is represented by Z⁻
Then, the set builder notation is
{x: x ∈ Z⁻, -10 < x < -3} and
The set is {-9, -8, -7, -6, -5, -4}

D)-5x = -10
Step-by-step explanation:
The equation results from adding the equations in this system is -5x = -10.
Option D is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 7 is an equation.
We have,
-8x + 8y = 8 _____(1)
3x - 8y = -18 _____(2)
Now,
Adding (1) and (2) we get,
-8x + 8y + 3x - 8y = 8 - 18
-5x = -10
Thus,
-5x = -10 is the equation.

A company manufactures handband a wirleless
Answers
Answer:
1. 21 represents the cost of manufacturing one handband.
3. The initial start up cost is $15000.
5. The company spends $57000 to manufacture 2000 handbands.
Step-by-step explanation:
We are given the cost function for manufacturing 'h' amount of handbands and it is provided that there was initial start up costs involved.
Now, as the cost function is given by, C(h) = 21h + 15000.
We can see that the initial start up cost is $15000.
As, 'h' is the number of handbands being made. So, 21h in C(h) is the cost of manufacturing 'h' handbands.
Therefore, 21 is the cost of manufacturing one handband.
Since, C(h) = 21h + 15000.
Substituting h = 2000, we get,
C(2000) = 21×2000 + 15000.
i.e. C(2000) = 42000 + 15000.
i.e. C(2000) = 57000.
The company spends $57000 to manufacture 2000 handbands.
Since, we are provided with only cost function, we can not talk about the profit.
Hence, option 1, 3 and 5 are correct.
PLEASE MARK ME BRAINLIST!

1. 21 represents the cost of manufacturing one handband.

a box in the shape of a rectangular prism has the dimensions shown. what length of the interior diagonal of the box? round to the nearest tenth.
100 cm
80 cm
60 cm
Answers
Answer:
I keep getting 141.421... so rounded it would be 141.4
Step-by-step explanation:
The length of the interior diagonal of the box is approximately 141.4 cm.
How to find the volume and base's area of a right rectangular prism?Suppose the base of the prism has length = l units, and width = w units.
Suppose that the height of the prism is of h units, then:
[tex]v = \dfrac{l \times w \times h}{3} \: \rm unit^3[/tex]
is the volume of that prism.
The base is a rectangle with length = L units, and width = W units, so its area is:
[tex]b = l \times w\: \rm unit^2[/tex]
We are given that;
Height= 100cm
Width=80cm
Length=60cm
Now,
Using the Pythagorean theorem, we can find the length of the interior diagonal as:
diagonal = sqrt(l^2 + w^2 + h^2)
diagonal = sqrt(100^2 + 80^2 + 60^2)
diagonal = sqrt(10000 + 6400 + 3600)
diagonal = sqrt(20000)
diagonal ≈ 141.4
Therefore, the length of the diagonal of prism will be 141.4

On the first day it was posted online, a music video got 1750 views. The
number of views that the video got each day increased by 20% per day. How
many total views did the video get over the course of the first 5 days, to the
nearest whole number?
Answers
To find the total views a music video got over the first 5 days with a 20% daily increase, calculate the views for each day using a geometric sequence formula and sum them, resulting in approximately 13023 views.
Explanation:To calculate the total views a music video got over the course of the first 5 days with a 20% daily increase starting at 1750 views, we use the geometric sequence formula V = V0 × (1 + r)n, where V0 is the initial number of views (1750), r is the daily increase rate (0.20), and n is the day number. The total views (TV) over 5 days is calculated by summing the individual daily views.
Day 1: 1750 views
Day 2: 1750 × (1 + 0.20) = 2100 views
Day 3: 1750 × (1 + 0.20)2 = 2520 views
Day 4: 1750 × (1 + 0.20)3 = 3024 views
Day 5: 1750 × (1 + 0.20)4 = 3628.8 views, rounded to 3629 views
The total views over the five days is the sum of daily views: 1750 + 2100 + 2520 + 3024 + 3629 = 13023 views.

Please help me :( solve for x and y. y = 4x and 3x + 2y = 55
Answers
Final answer:
To solve the system of equations y = 4x and 3x + 2y = 55, you can substitute 4x for y in the second equation, simplify to find x = 5, and then calculate y = 20.
Explanation:
To solve for x and y using the equations y = 4x and 3x + 2y = 55, you can use substitution or elimination. Let's use substitution since we already have y expressed in terms of x.
Substitute 4x for y in the second equation: 3x + 2(4x) = 55.
Simplify and solve for x: 3x + 8x = 55 becomes 11x = 55, so x = 5.
Substitute x back into the first equation to find y: y = 4(5), so y = 20.
Therefore, the solution to the system of equations is x = 5 and y = 20.

Find the point slope equation for the line that passes through the points ( -2, -20 ) and (9, 79). Use the first point in your equation y+ =
Answers
The point-slope equation for the line passing through (-2, -20) and (9, 79), is y = 9x - 2.
To find the point-slope equation for the line that passes through the points (-2, -20) and (9, 79), we first need to calculate the slope (m). The formula for the slope is given by:
m = (Y2 - Y1) / (X2 - X1)
Using the given points, we get:
m = (79 - (-20)) / (9 - (-2)) = 99 / 11 = 9
Now, using the point-slope form of the equation y - y1 = m(x - x1), and the first point (-2, -20), we have:
y - (-20) = 9(x - (-2))
Simplifying this, we get:
y + 20 = 9(x + 2)
Or
y = 9x + 18 - 20
y = 9x - 2
This is the point-slope equation for the line that passes through the points.

The height of a cylinder is 12 inches and the radius is 3.5 inches. What is the approximate volume of the cylinder?
Answers
Answer:
V≈461.81in³ That is the answer!
V = pi*r^2*h
V = pi*(3.5)^2*12
V = pi*12.25*12
V = pi*147
V = 147pi .... exact volume in terms of pi
V = 461.8141200777 is the approximate volume (use a calculator here)
The units for the volume are in cubic inches
Side note: If you use pi = 3.14, then you'll get an approximate volume of 147*pi = 147*3.14 = 461.58 which is a bit off from the other value we got earlier due to the fact pi = 3.14 is not as accurate as using the calculator's internal value of pi.
