Answer:
The distance of the line is 10.82
Step-by-step explanation:
Distance Between two Points in the Plane
Given two points A(x1,y1) and B(x2,y2), the distance between them is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The graph clearly shows the points (-5,4) (4,-2), thus the distance is:
[tex]d=\sqrt{(4-(-5))^2+(-2-4)^2}=\sqrt{9^2+(-6)^2}[/tex]
[tex]d=\sqrt{81+36}=\sqrt{117}=10.82[/tex]
The distance of the line is 10.82

What is the significance of a correlation coefficient of -0.97?
A. The points all lie very close to the line of fit, and the
line is decreasing.
B. The points all lie very close to the line of fit, and the
line is increasing.
C. The points do not follow the line of fit and, the line is
decreasing.
D. The points do not follow the line of fit, and the line is
increasing.
Answer:
It's A. The points all lie very close to the line of fit, and the line is decreasing.
Step-by-step explanation:
The points all lie very close to the line of fit, and the line is decreasing option (A) is correct.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
It is given that:
The value of the correlation coefficient r = -0.97
As we know,
If the value of the correlation coefficient is positive it represents the line of best-fit increasing.
If the value of the correlation coefficient is negative it represents the line of best fit decreasing.
If the value of r is close to 1 then we can say that the correlation between the two variables is very strong.
Thus, the points all lie very close to the line of fit, and the line is decreasing option (A) is correct.

Which math PROPERTY is this? If 12 = 17 - 5, then 17 - 5 = 12
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.
Tip: The symmetric property of equality states that no matter what side the equations and answer are it will still be equal, but it only works for the equal sign.
The math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.
What is Number system?A number system is defined as a system of writing to express numbers.
Given that 12 = 17 - 5, then 17 - 5 = 12
we need to check which property will be used.
The math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.
The symmetric property of equality is really quite simple. This property states that if a = b, then b = a. That is, we can interchange the sides of an equation, and the equation is still a true statement.
Hence, the math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.

In the diagram below, find the value of y....
Answer:
y = 130
Step-by-step explanation:
(4x+8) + (3x-19) + (x+7) = 180
4x + 8 + 3x - 19 + x + 7 = 180
(4x + 3x + x) + (8 -19 + 7) = 180
8x - 4 = 180
8x -4 +4 = 180 +4
8x = 184
8x/8 = 184/8
x = 23

Answer:
T=38
Step-by-step explanation:
t−8+13=43
Step 1: Simplify both sides of the equation.
t−8+13=43
t+−8+13=43
(t)+(−8+13)=43(Combine Like Terms)
t+5=43
t+5=43

In Mathematics, you must have learned about different types of equations. Here, we are going to discuss the difference between linear and nonlinear equations. The difference between them described here with the help of definitions and examples.
We come across a lot of equations while solving maths problems. Some equations include only numbers and some consist of only variables and some consists of both numbers and variables. Linear and nonlinear equations usually consist of numbers and variables.
Definition of Linear and Non-Linear Equation
Linear means something related to a line. All the linear equations are used to construct a line. A non-linear equation is such which does not form a straight line. It looks like a curve in a graph and has a variable slope value.
The major difference between linear and nonlinear equations is given here for the students to understand it in a more natural way. The differences are provided in a tabular form with examples.
What is the difference between Linear and Nonlinear Equations?
To find the difference between the two equations, i.e. linear and nonlinear, one should know the definitions for them. So, let us define and see the difference between them.
Linear Equations
Non-Linear Equations
It forms a straight line or represents the equation for the straight line It does not form a straight line but forms a curve.
It has only one degree. Or we can also define it as an equation having the maximum degree 1. A nonlinear equation has the degree as 2 or more than 2, but not less than 2.
All these equations form a straight line in XY plane. These lines can be extended to any direction but in a straight form. It forms a curve and if we increase the value of the degree, the curvature of the graph increases.
The general representation of linear equation is;
y = mx +c
Where x and y are the variables, m is the slope of the line and c is a constant value.
The general representation of nonlinear equations is;
ax2 + by2 = c
Where x and y are the variables and a,b and c are the constant values
Examples:
10x = 1
9y + x + 2 = 0
4y = 3x
99x + 12 = 23 and
Examples:
x2+y2 = 1
x2 + 12xy + y2 = 0
x2+x+2 = 25
Note:
The linear equation has only one variable usually and if any equation has two variables in it, then the equation is defined as a Linear equation in two variables. For example, 5x + 2 = 1 is Linear equation in one variable. But 5x + 2y = 1 is a Linear equation in two variables.
Let us see some examples based on these concepts.
Solved Examples
Example: Solve the linear equation 3x+9 = 2x + 18.
Solution: Given, 3x+9 = 2x + 18
⇒ 3x - 2x = 18 - 9
⇒ x = 9
Example: Solve the nonlinear equation x+2y = 1 and x = y.
Solution: Given, x+2y = 1
x = y
By putting the value of x in the first equation we get,
⇒ y + 2y = 1
⇒ 3y = 1
⇒ y = ⅓
∴ x = y = ⅓
What is the key difference between non-linear and linear equations?
A linear equation is used to represent a straight line in a graph, whereas non-linear equations are used to represent curves.
How does the graph of linear and non-linear equations look?
A linear equation graph is a constant slope whereas the graph of the non-linear equation shows the variation in slope at different points.
How is the linear equation represented? Give an example.
The general representation of linear equation is y = mx+c,
where m = slope of the line
x and y are the variables
c is the intercept (constant value)
Example: 2x+y=1
y=-2x+1
How is the nonlinear equation formed?
A non-linear equation is generally given by ax2+by2 = c
where x and y are variables
a,b and c are constant values.

TU is parallel to IJ. So ∠I and ∠T are corresponding angles, and ∠U and ∠J are corresponding angles.
By AA similarity, ΔHTU and ΔHIJ are similar.
Write a proportion:
HT / HI = HU / HJ
Plug in values:
4 / 10 = x / (x + 9)
Cross multiply:
4 (x + 9) = 10x
4x + 36 = 10x
36 = 6x
x = 6
So HU = 6, and HJ = 6 + 9 = 15.

Answer:
The slope-intercept form is y = [tex]-\frac{3}{4}[/tex] x + 8 ⇒ B
Step-by-step explanation:
The slope-intercept form of the linear equation is:
y = m x + b, where
m is the slopeb is the y-interceptFrom the given in the question
∵ The slope of the line is [tex]-\frac{3}{4}[/tex]
∴ m = [tex]-\frac{3}{4}[/tex]
→ Substitute its value in the form of the equation above
∴ y = [tex]-\frac{3}{4}[/tex] x + b
→ To find b substitute x and y by the coordinates of any point on the line
∵ The line passes through the point (8, 2)
∴ x = 8 and y = 2
∵ 2 = [tex]-\frac{3}{4}[/tex] (8) + b
∴ 2 = -6 + b
→ Add 6 to both sides to find b
∴ 2 + 6 = -6 + 6 + b
∴ 8 = b
→ Substitute the value of b in the equation above
∴ y = [tex]-\frac{3}{4}[/tex] x + 8
∴ The slope-intercept form is y = [tex]-\frac{3}{4}[/tex] x + 8

jk 10/3, 3 1/3
The fraction 6/20 can also be simplified to 3/10, which is the same as 0.3 in decimal form.
To calculate 6 divided by 20, you simply perform the division operation. Divide the numerator (6) by the denominator (20):
6 ÷ 20 = 0.3
The result of 6 divided by 20 is 0.3. This means that if you divide 6 into 20 equal parts, each part will be 0.3.
In decimal form, the fraction 6/20 is equivalent to 0.3. Decimal notation is useful when dealing with fractions that don't easily simplify into whole numbers. In this case, the division results in a decimal less than 1, representing a fraction that is less than a whole. The fraction 6/20 can also be simplified to 3/10, which is the same as 0.3 in decimal form.
