Gabriella needs 120120 meters of fence to surround a rectangular garden. The length of the garden is three times its width, ww. How wide is the fence?.
The rectangular garden's width is 15 units, and Gabriella needs 120 meters of fence to enclose it.
The perimeter of a rectangle is the length of its side boundaries. A rectangle's perimeter is equal to twice the product of its length and width.
[tex]P=2(l+w)[/tex]
In this case, the rectangle's length is (l) and its width is (w).
Assume for a moment that the garden is l units long. The garden is three times longer than it is wide, w. Thus,
[tex]l=3w[/tex]
Gabriella requires 120 meters of fencing to enclose a square garden. The perimeter of the rectangular garden is the same height as this fence. Thus,
[tex]P=2(l+w)\\120=2(l+w)[/tex]
Add this equation with the length value from equation 1.
[tex]120=2(3w+w)\\3w+w=\frac{120}{2} \\4w=60\\w=\frac{60}{4} \\w=15[/tex]
Gabriella needs 120 meters of fence to enclose the rectangular garden, which has a width of 15 units.

what is the slope between (-9,3) and (-1,1)
Answer:
m = -1/4
Step-by-step explanation:
The slope is rise/run or (y2 - y1) / (x2 - x1)
We see the y decrease by 2 and the x increase by 8, so the slope is
-2/8 = -1/4
Answer:
Slope = -1/4
Step-by-step explanation:
Now we have to,
→ find the needed slope.
Formula we use,
→ Slope(m) = (y2 - y1)/(x2 - x1)
Then the slope will be,
→ m = (y2 - y1)/(x2 - x1)
→ m = (1 - 3)/(-1 -(-9))
→ m = -2/(-1 + 9)
→ m = -2/8
→ [ m = -1/4 ]
Hence, the slope is -1/4.

Determine the largest integer value of x in the solution of the following inequality.
2x+6<-4
Answer: -6
Step-by-step explanation: To determine the largest integer value of x in the solution of the inequality 2x+6<-4, we first need to isolate x on one side of the inequality. We can do this by subtracting 6 from both sides of the inequality, which gives us 2x<-10. Next, we can divide both sides of the inequality by 2, which gives us x<-5. Since the inequality has a strict inequality symbol, we can conclude that the largest integer value of x that satisfies the inequality is -6.
What is the equation in slope intercept form of the line that is parallel to the given line?
The equation in slope intercept form of line , parallel to the line 6x - y = 1 and passing through point (-2,2) is y = 6x + 14 .
When the two line are parallel , then their slopes are same .
the required line is parallel to the given line 6x - y = 1 ,
rewriting it , we get ;
y = 6x - 1 ;
on comparing it with the slope intercept form of line , "y = mx + c" ,
we get ,
slope(m) ⇒ 6 .
So , the equation of the required line becomes ⇒ y = 6x + c ;
Since this line passes through the point (-2,2) ,
we get ,
2 = 6(-2) + c ;
2 = -12 + c ;
c = 12 + 2 ;
c = 14 .

Consider the mathematical sentence 2 ≠ 3.
Is there any variable or constant that you could add to or subtract from both sides, or
multiply or divide both sides by using the Properties of Equality to make both sides equal?
Choose variables and constants to create new mathematical sentences to justify
your conclusion.
Answer:
It is not possible to make both sides of the mathematical equation 2 ≠ 3 equal by using the Properties of Equality. This is because the equation is already in reduced form and there is no way to simplify it further.
If we try to apply the Properties of Equality to this equation, we can see that it is not possible to make both sides equal. For example, if we try to add or subtract a constant or variable to both sides, the result will not be modified. If we try to multiply or divide both sides by a constant or variable, the result will also not be modified.
Therefore, it is not possible to make both sides of the mathematical equation 2 ≠ 3 equal using the Properties of Equality.
What is the factored form of 3x² 14x 8?
The factored form of 3x² + 14x + 8 is (3x + 4)(x + 2).
What is factor?Factor is a number that can be divided evenly into another number. Factors are used in mathematics to simplify equations, calculate percentages, and solve problems. Factors can also be used to identify the greatest common factor (GCF) between two or more numbers. Factors can also be used to find the least common multiple (LCM) of two or more numbers.
This is the product of the two binomials (3x + 4) and (x + 2),which are the factors of the equation.
The process of factoring an equation involves breaking it down into its component parts,
which in this case are 3x² + 14x + 8. The factors of this equation are determined by first finding the greatest common factor (GCF) of the terms, which in this case is 3x + 4.
Then, the GCF is divided by each of the terms to determine the other factor. For example, 3x² / 3x + 4 =x + 2.
When the two factors are multiplied together, the result is the original equation.

How to obtain the length of AB?The length of AB, from the sketch of the triangle given by the image at the end of the answer, is obtained using the law of cosines, as follows:
x² = a² + b² - 2abcos(C).
The parameters from the triangle are given as follows:
a = 8, b = 15, C = 70º.
Hence the length of AB is given as follows:
x² = 8² + 15² - 2 x 8 x 15 x cos(70º)

x = square root of 207
x = 14.387.
How to obtain te measure of angle BAC?
The measure of angle BAC is obtained using the law of sines, as follows:
sin(x)/15 = sin(70º)/14.387
sin(x) = 15 x sin(70º)/14.387

What is 5x 2y 3 in slope intercept form?
The line's equation is written as y = (-5/2)x + (3/2) in slope-intercept form.
According to the slope-intercept form, in the equation for a straight line, y=mx+b, the slope is the quantity represented by m that is multiplied on the x, and b is the y-intercept, i.e., the point where the line crosses the vertical y-axis.
To put the equation 5x + 2y = 3 in slope-intercept form, you need to rearrange the equation to have the form y = mx + b, where m is the slope and b is the y-intercept.
To do this, you can start by isolating the y term on one side of the equation:
5x + 2y = 3
2y = -5x + 3
y = (-5/2)x + (3/2)

The line 2y + x = 1 is perpendicular to a line L. Line L passes through point (2, -1). Determine the equation of L in the form y = mx + c, where m and c are constants.
The equation of the perpendicular line is y = 2x - 5
How to determine the perpendicular line equation?From the question, we have the following parameters that can be used in our computation:
2y + x = 1
Make y the subject
y = -1/2x + 1/2
Also, from the question;
We have the following points
Point = (2, -1) i.e. (x, y) = (2, -1)
The equation of a line can be represented as
y = mx + c
Where
Slope = m
By comparing the equations, we have the following
m = -1/2
This means that the slope is -1/2
The slopes of perpendicular lines are opposite reciprocals
This means that the slope of the other line is 2
The equation of the line is then calculated as
y = m(x - x₁) +y₁
Where
m = 2
(x₁, y₁) = (2, -1)
So, we have
y = 2(x - 2) - 1
Evaluate
y = 2x - 5
Hence, the line has an equation of y = 2x - 5

Define regression.A statistical measure that identifies the link or co-relationship between two variables. explains the relationship between an independent variable and a dependent variable. The scatter of data points around the regression line plays a key role in estimating the slope's uncertainty in regression analysis. The data points are more dispersed and the estimation of the slope is less accurate when there is a lot of scatter. Because the estimation of the slope is based on the data points, it is less accurate when there is greater scatter in the data points.
Given
When I. there is a lot of scatter around the regression line, b1 is higher.
I am higher. The uncertainty surrounding the slope estimate, b1, increases with the amount of scatter around the regression line. The calculated slope is less dependable when there is a lot of scatter than when there is very little scatter.
When there is a large amount of scatter around the regression line, the uncertainty associated with the slope estimate, b1, is higher. This is due to the fact that the estimate of the slope depends on the data points, and when there is a lot of scatter, the data points are more dispersed, making the estimate of the slope less accurate.
