Answer:

x= 3     y= 1

Step-by-step explanation:

4 * 3 (x)= 12 + 1 (y)= 13

5 * 3 (x)= 15 - 3*1 (y)= 15 - 3 (y)= 12

Both scenarios are now proven true.

Answer:

y = 3x - 6

Step-by-step explanation:

The equation is y = mx + b  

m = the slope

b = y-intercept

Slope = rise/run or (y2 - y1) / (x2 - x1)

Let's pick 2 points (0, -6) (2,0)

We see the y increase by 6 and the x increase by 2, so the slope is

m = 6/2 = 3

y-intercept located at (0, -6)

So, the equation is

y = 3x - 6

A line is parallel to x = -3 if and only if it has the same slope. The slope of a line perpendicular to x = -3 is undefined, because x = -3 is a vertical line, which has no slope. A vertical line is always parallel to itself.

Of 800 students in a university, 360, or 45%, live in dormitories. the 800 is an example of population size. Population size is a number that represents the total quantity of a particular group of items or people.

In this case, the population size is 800 students in a university. This population size is used to calculate the percentage of students who live in the dormitories. In this example, the percentage of students who live in the dormitories is 45% or 360 students.   Population size can be used to analyze different trends or patterns within a group of people.

For example, if the university wanted to determine the number of students who commute from home, they could use the population size of 800 students to calculate the percentage of students who commute from home. Similarly, the university could use the population size to calculate the percentage of students who live off-campus.   Population size can also be used to track changes over time.

For example, if the university wanted to determine if the number of students living in the dormitories had increased or decreased since last year, they could compare the current population size of 800 students with the population size from the previous year.

Answer:

If it's 16/(1+7) = 16/8 = 2, that'd be the answer

On solving the provided question we can say that by percentage 25% of 500 = 25/100 X 500 = 125 grams

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

The area of a circular fenced-in section for some of his animals is 240.625 square meter. So the option 1 is correct.

In the given question, we have to find the approximate area, in square meters, of the section.

Sam built a circular fenced-in section for some of his animals.

The section has a circumference of 55 meters.

As we know that, the circumference of circle = 2πr. So,

2πr = 55

Now putting, π = 22/7

2 × [tex]\frac{22}{7}[/tex] × r = 55

Multiply by 7 on both side, we get

44 × r = 385

Divide by 44 on both side, we get

r = 8.75

The area of circle = π[tex]r^2[/tex]

Now putting the value of r.

The area of circle = [tex]\frac{22}{7}\times(8.75)^2[/tex]

The area of circle = [tex]\frac{22}{7}[/tex] × 76.563

The area of circle = 240.625 square meter

Hence, the area of a circular fenced-in section for some of his animals is 240.625 square meter. So the option 1 is correct.

Answer: When two variables vary inversely, the product of their values is constant. This means that x * y = k, where k is a constant.

We are given that y = 14 when x = 3, so we can use this information to find the value of k:

k = x * y = 3 * 14 = 42

Now that we know the value of k, we can use it to find the value of y when x = 7:

y = k / x = 42 / 7 = 6

So, y = 6 when x = 7.

The width of Todor's area model is 5+3=8

The width of Todor's area model can be determined by factoring 10x² - 5x + 15. 10x², -5x, and 15 can be factored into

5(2x² - x + 3).

Since the greatest common factor of these terms is 5, Todor's area model can be represented as 5 multiplied by two rectangles.

The first rectangle would have a length of 2x² and a width of 5, and the second rectangle would have a length of x and a width of 3. Therefore, the total width of Todor's area model would be 5 + 3 = 8

Answer:

The slope of the line that passes through the points on the table is 2

Step-by-step explanation:

To find the slope, first pick any two points on the table and plug it into [tex]m = \frac{y2 - y1}{x2-x1}[/tex]

where m is the slope.

For example, let's use (x2, y2) as  (2, 1) and (x1, y1) as (1, -1)

[tex]m = \frac{1-(-1)}{2 -1}[/tex]

[tex]m =\frac{1+1}{1}[/tex]

[tex]m=2/1[/tex]

m = 2

So the slope is 2.

Therefore , the solution of the given problem of triangle comes out to be the street is 0.24 kilometers long.

A triangle is classified as a polygon since it has four or segments. It is a basic geometric form. Triangle ABC denotes a triangle having faces A, B, or C. Therefore, in Euclidean geometry, a single planar and square are produced where sides are not collinear. A triangle is a polygon if it has three sides or three corners. The points where a triangle's three sides come together are at its corners. Those three triangle angles add up to 180 degrees.

Here,

Given:

5th Avenue and 6th Avenue run parallel to one another.

The length of the main street between Fifth and Sixth Avenues shall be.

Now that we have used the triangle proportionality theory, we have:

=> 0.4 /x = 0.5/0.3

=> 0.4 - 0.3 = 0.5x

Answer: x=-3, y=-4

Step-by-step explanation:

System of equations is actually pretty simple.

Let me explain the two methods of solving a system of equations problem.

1. Elimination method

y-2x=2

-y=-x+1

In this approach, we will subtract or add the two equations together to eliminate one variable.

So in this problem, we'll organize -y=-x+1 like this:

x-y=1

Now we have

-2x+y=2

x-y=1

All we have to do now is add the two equations together and:

-x=3

x=-3

As you can see, the y variable is gone and we can find x by simply solving the rest.

Now we know that x=-3, let's plug in the value to get y.

x-y=1

-3-y=1

-y=4

y=-4

Therefore, x=-3, and y=-4

2. Substitution method

Let's go back to the problem.

y-2x=2

-y=-x+1

Now let's say that we will solve the problem using the substitution method.

In this approach, we will express one variable with the other.

So what we do is express y with x:

-y=-x+1

y=x-1

Now that we went through that process, we can plug in the y in the other equation:

x-1-2x=2

-x-1=2

-x=3

x=-3

Now that we now x=-3, let's plug that in to get y.

y=-3-1

y=-4

So the answer: x=-3, y=-4

Do you see the pattern?

System of equations problems are all about eliminating one variable and using the value of one to find the other.

Step-by-step explanation:

25 rounded to the nearest tenth would be rounded up to 30. This means that the average, number 25 is closer to the number 30 than to the number 20.

Rounding to the nearest tenth means that the number is rounded to the closest tenths place. In this case, 25 would be rounded average up to 30. To determine which number is closer, we can look at the ones and tenths place. 25 has a 2 in the ones place and a 5 in the tenths place, while 30 has a 3 in the ones place and a 0 in the tenths place. Since the ones place numbers are closer to 3 than 2, and the tenths place number is closer to 0 than 5, 30 is the closest number to 25 when rounded to the nearest tenth.

The inequality that is represented by the given graph is; y ≥ 2x - 5

The formula for equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

From the given linear graph, we see that the y-intercept is at y = -5

The slope is gotten by using two coordinates (3, 1) and (4,3) using the formula;

Slope = (y₂ - y₁)/(x₂ - x₁)

Slope = (3 - 1)/(4 - 3)

Slope = 2

Since the Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region, then this is ≤ or ≥ .

The slope of the line with the given coordinates A(-2,2) and B(0,4) is 1.

Slope is simply expressed as change in y over the change in x.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Given the data in the question;

Point A (-2,2)

Point B (0,4)

Plug the given x and y values into the slope formula and simplify.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Slope m = ( 4 - 2 )/( 0 - (-2) )

Slope m = ( 2 )/( 2 )
