Answer:
7/2
Step-by-step explanation:
7x – 2y = 10
using ( y = mx + b) as our guideline
where m is the slope
7x – 2y = 10
subtract 7x from both sides
7x – 7x – 2y = 10 – 7x
–2y = 10x – 7x
when arranged in slope form
–2y = –7x + 10
divide both sides by (–2) to get y
[tex] \frac{ \\ - 2y}{ - 2} = \frac{ - 7x}{ - 2} + \frac{10}{ - 2} [/tex]
[tex]y = \frac{ \\ 7y}{2} - 5[/tex]
[tex]the \: slope \: will \: be \: \frac{ \\ 7}{2} [/tex]
This is our answer.

Answer:
[tex]x = 58[/tex]
[tex]y = 90[/tex]
Step-by-step explanation:
This is a rhombus becuase it a quadralterial and it has four right triangles, and it diagonals bisect each others so it cant be a trapezoid, and paralleolgram. and it doesnt have four right corner angles so it cant be a square or rectangle or kite.A rhombus inner angle measure is 90 degrees.
So
[tex]y = 90[/tex]
This means the upper left angle of the top triangle measure is 58 becuase triangle interior theorem.
Since a rhombus bisects angles, angle x measure 58.

Answer:
x axis
Step-by-step explanation:
Answer:
y=-5x+4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-(-6))/(1-2)
m=(-1+6)/-1
m=5/-1
m=-5
y-y1=m(x-x1)
y-(-6)=-5(x-2)
y+6=-5(x-2)
y=-5x+10-6
y=-5x+4

How the Earth rotates around the sun and moon?
The Earth orbits the Sun and rotates around its own axis. The Moon orbits the Earth and is held in place by the Earth’s gravity. This is why the length of a day is gradually increasing over time.
The Moon’s gravitational pull causes the tides, which is why the ocean’s water level rises and falls. The gravitational pull of the Moon also affects the Earth’s rotation by slowing it down slightly. This is why the length of a day is gradually increasing over time.

3. A sample of 10 networking sites for a specific month has a mean number of visits of 26.1 and a sample standard deviation of 4.2. Find a 99% confidence interval of the population mean.
The confidence interval is (22.68,29.52).
In statistics, a confidence interval describes the likelihood that a population parameter would fall between a set of values for a given percentage of the time. Confidence ranges that include 95% or 99% of anticipated observations are frequently used by analysts. Therefore, it can be concluded that there is a 95% probability that the true value falls within that range if a point estimate of 10.00 is produced using a statistical model with a 95% confidence interval of 9.50 - 10.50.
n = 10
x = 26.1
s = 4.2
Two-sided confidence interval :
CI = [tex](x-\frac{z*s}{\sqrt{n}},x+\frac{z*s}{\sqrt{n} } )[/tex]
= [tex](26.1-\frac{2.576*4.2}{\sqrt{10}},26.1+\frac{2.576*4.2}{\sqrt{10}} )[/tex]
= (26.1−3.42,26.1+3.42)
= (22.68,29.52)
Hence, the confidence interval is (22.68,29.52).

The unknown number deduced by solving the equation 4x - 1 = 6x +9 is -5.
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
Let the unknown number be x.
First multiply the number by 4 = 4x
Then subtract 1 from it = 4x -1
This results in the same number as when the number is multiplied by 6 and 9 is added to it = 6x + 9.
So the equation will be -
4x - 1 = 6x +9
4x - 6x = 9 + 1
-2x = 10
-x = 10/2
x = -5
Therefore, the number obtained is -5.

Miguel has three times as many dimes as he has quarters. He has as many nickels.as he has dimes and quarters.combined. The total amount of money he has is $3.00. How many of each coin does Miguel have?
Answer:
Step-by-step explanation:
fter solving the algebraic equation, Miguel has 4 quarters, 12 dimes and 16 nickels.
What is algebra?
One of the earliest areas of mathematics that deals with number theory, geometry, and analysis is algebra. Algebra is also defined as the study of mathematical rules and symbols through the manipulation of those mathematical symbols.
The number of quarters is taken to be x, then the number of dimes will be 3x, and the number of nickels will be 3x + x = 4x
$3.00 when converted to cents is 300 cents.
The value of nickels is 5 x 4x=20x.
The value of dimes is 10 x 3x=30x.
The value of quarters is 25x.
As the total value of money Miguel has is 300 cents, then the algebraic equation will be -
20x + 30x + 25x = 300
Solve to get the value of x -
75x = 300
x = 4
Therefore, the amount of quarters is x = 4 quarters.
The amount of dimes is x = 3x = 3 x 4 = 12 dimes.
The amount of nickels is 4x = 4 x 4 = 16 nickels.

Which of these characteristics of a star make it most likely to become a black hole? Select the two correct answers.
A. Its mass is equal to that of the sun.
B. It has an abundant supply of hydrogen.
C. Its mass is greater than 20 times the mass of the sun.
D. It is dying.
The two characteristics of a star to become a black hole are:
Its mass is greater than 20 times the mass of the Sun.It is dying.The correct options are C and D.
When a star has consumed all its fuel (like hydrogen), that is to say, when it is at the end of its life, it can become a black hole. For this to happen, the mass of the star must be greater than 20 times the mass of the Sun. If a star is at the end of its life cycle but has a mass that is less than 20 times the Sun's mass, it will not become a black hole.
The given options:
A. Its mass is equal to that of the sun. False
Its mass must be greater than 20 times the mass of the Sun.
B. It has an abundant supply of hydrogen. False
When it has an abundant supply of hydrogen, the star is at the beginning or the middle of its life cycle, and to become into a black hole it must be at the end of it.
C. Its mass is greater than 20 times the mass of the Sun. True
Yes, its mass must be greater than 20 times the mass of the Sun.
D. It is dying. True
The star must have no more fuel to continue its life cycle.
Therefore, options C and D are correct.

What is the difference between a problem and an algorithm?
A problem is just a function or even a mapping of inputs to outputs. An algorithm is a recipe for solving a problem with concrete and unambiguous steps.
What is algorithm?In mathematics and computer science, an algorithm is a finite sequence of rigorous instructions used to solve a class of specific problems or perform a computation.
Algorithms are data calculation and processing specifications. More advanced algorithms can use conditionals to divert code execution through various paths (referred to as automated decision-making) & deduce valid inferences (referred to as automated reasoning), eventually achieving automation.
Alan Turing used metaphorical terms like "memory", "search," and "stimulus" to describe machines.
