Answers
Answer: y = 1/12x
Step-by-step explanation:
(24, 2)
(12, 1)
find slope (y2 - y1) / (x2 - x1)
2 - 1 / 24 - 12
1 / 12
find y intercept
y = mx + b
1 = 1/12(12) + b
1 = 1 + b
b = 0
y = 1/12x + 0
y = 1/12x
Step by step
First let’s find slope using slope formula
y2 - y1 over x2 - x1
We know the minutes are x
We know the cups of water is y
Points (12, 1) and (24, 2)
2 - 1 over 24 - 12
1 over 12 or 1/12 slope
Now we can write an equation using point slope formula. Y - y1 = m (x - x1) using any set of points, let’s use (12, 1)
y - 1 = 1/12 (x - 12)
y - 1 = 1/2x - 1
Add 1 to both sides to isolate y
y -1 + 1 = 1/12x -1 + 1
y = 1/12x
This is your answer
So your relationship between x and y is
y is equal to 1/12 of x
Let’s check our work
x = 12
1/12 x 12 = 1, so y = 1 when x = 12, this is true according to your chart
x = 24
1/12 x 24 = 2, so y = 2 when x = 24, this is true according to your chart.
What is the solution of the linear-quadratic system of equations? { y = x 2 + 5 x − 3 y − x = 2
Answers
The two solutions for the system of equations:
y = x^2+ 5x - 3
y - x = 2
Are:
(-5, -7) and (1, -1)
How to solve the system of equations?Here we have the following system of equations:
y = x^2+ 5x - 3
y - x = 2
We can replace the first equation into the second one to get:
(x^2+ 5x - 3) - x = 2
x^2 + 4x - 3 = 2
x^2 + 4x - 3 - 2 = 0
x^2 + 4x - 5 = 0
Using the quadratic formula, we will get the solutions:
[tex]x = \frac{-4 \pm \sqrt{4^2 - 4*1*-5} }{2} \\\\x = \frac{-4 \pm 6}{2}[/tex]
The two solutions are:
x = (-4 - 6)/2 = -5
x = (-4 + 6)/2 = 1
To find the values of y, we can evaluate the linear equation:
when x = -5
y - (-5) = -2
y + 5 = -2
y = -2 - 5 = -7
So one solution is (-5, -7)
when x = 1
y - 1 = -2
y = -2 + 1 = -1
The other solution is (1, -1)

System of Linear EquationThe system of linear equations is the set of two or more linear equations involving the same variables. Here, linear equations can be defined as the equations of the first order, i.e., the highest power of the variable is 1. Linear equations can have one variable, two variables, or three variables. Thus, we can write linear equations with n number of variables.
In the problem, given the system of linear equations are

When Kelsey is not on the moving sidewalk, she can walk the length of the sidewalk in 3 minutes. If she stands on the sidewalk as it moves, she can travel the length in 2 minutes. If Kelsey walks on the sidewalk as it moves, how many minutes will it take her to travel the same distance? Assume she always walks at the same speed.
Answers
Answer:
1.2 minutes
Step-by-step explanation:
Kelsey moves 1/3 length per minute. The sidewalk moves 1/2 length per minute. Walking on the sidewalk, Kelsey moves (1/3+1/2) = 5/6 lengths per minute, or 6/5 minutes per length.
So it takes Kelsey 1 1/5 minutes to walk the length on the moving sidewalk.

What is congruent triangle?When two triangles are congruent, their three sides and their three angles match precisely.If there is a turn or a flip, the equal sides and angles might not be in the same place, but they are still present.Formally speaking, two sets of points are said to be congruent if—and only if—they can be changed into one another by an isometry, which is a combination of rigid motions like translation, rotation, and reflection. Therefore, if two separate plane figures on a piece of paper can be cut out and then perfectly fitted up, they are congruent.It is given that
O is the midpoint of NP,
NP is perpendicular to MN, and
NP is perpendicular to PQ.

What is division?One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division.
The other operations are multiplication, addition, and subtraction.
In mathematics, the division is the process of dividing a number into equal parts and calculating the maximum number of equal parts that may be formed.
For instance, dividing 15 by 3 results in the division of 15 into 3 groups of 5 each.
The division sign, "," or occasionally "/," is used in computer code.
So, we know that: Total seeds are 2700 and the total rows are 9
If there are the same amount of seeds in each row.
Following that, the number of seeds will be put in each row.
= (Total seeds) ÷ (Total rows)
= 2700÷9
= 300
Therefore, using division we know that (D) 2700÷9=300 is the basic fact using which John will get t know how many seeds will be planted in a row.

The line parallel to the given line 2x+2y=-12 is also -1.
Define slope.
Slope of a line refers to the measure of the steepness and the direction of a line.
Illustrate y= m x+ c.
y = mx + c refers to an equation of a line having a gradient of m and a y-intercept of c. This equation is often referred to as the slope-intercept form of the equation of a line.
We know that,
The general equation of a line is y=m x+ c,
where m = slope and b = y-intercept, c is a constant
Now, the equation of the given line is,
2x+2y=-12
⇒x + y=-6
Now expressing the equation in the form of y=m x+ c
So, y=-6-x
Further, on rearranging we get y= (-1) x-6
y = mx + c
So, according to the equation,on comparing we get
m=-1 and c=-6
On comparing, the slope of the given line is -1.

The equation to model the cost 'y' based on the number of movies streamed 'x' would be 14 = 2x and 20 = 6x.
What is a linear equation in one variable?
The linear equation in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
For the first case:
If 2 movies are streamed, the cost is $14 per month
So the cost = number of movies * cost per movie
y = 2*x
14 = 2x
For the second case:
If 6 movies are streamed, the cost is $20 per month
So the cost = number of movies * cost per movie
y = 6*x
20 = 6x
Hence the equation to model the cost 'y' based on the number of movies streamed 'x' would be 14 = 2x and 20 = 6x.

The decibel level of the noise from a motorcycle with intensity 10⁻² watts per square inch (W/in²) is equal to 50 dB.
What is sound intensity?In Science, sound intensity can be defined as a measure of the power of a sound wave per unit area. This ultimately implies that, sound intensity is a quantity that is typically be used for measuring the energy of sound and its unit of measurement is Watts per square meter (W/m²) or .
How to calculate the sound intensity level?Mathematically, sound intensity level or decibel level can be calculated by using this formula:
[tex]\beta = 10 log(\frac{I}{I_{ref}} )[/tex]
Note: The reference value of sound intensity is equal to 1.0 × 10⁻¹² watts per square inch (W/in²).
Since the intensity of the noise from this motorcycle is 10⁻² W/in², the decibel level (in dB) would be calculated as follows:
Decibel level, β = 10 × log(10⁻²/10⁻¹²)
