By using the property of linear pair we can prove that m∠2=m∠3 .
Let us use the template that is provided to find the solution.
1. ∠1 and ∠2 are supplementary (Linear pair)
∠3 and ∠4 are supplementary.
2.m∠1 + m∠2 = 180° (definition of supplementary angles.)
3.m∠3 + m∠4 = 180° (definition of supplementary angles.)
4.m∠1 + m∠2 = m∠3 + m∠4 (Substitution property)
or, m∠1 + m∠2 = m∠1 + m∠3
5. m∠1 =m∠4 (given)
6. m∠2 = m∠3 ( Subtraction property)
Therefore we can see that the two angles are equal due to the properties of linear pair and substitution property.
A linear pair of angles is formed when two straight lines intersect at only 1 single point. The angles are known to be a linear pair if they exactly follow the point where the two straight lines intersect only in a straight line. The sum of the angles in a pair of linear equations is always equal to 180°.

Here, we are given 3 pairs of expression. Let us evaluate them one by one.
[tex]9^{-2}[/tex] _ [tex](\frac{1}{9}) ^{-1}[/tex]
The negative exponent means that the base is the reciprocal raised to a positive power. Thus, [tex]9^{-2}[/tex] can be written as- [tex](\frac{1}{9}) ^{2}[/tex] = 1/81
similarly, [tex](\frac{1}{9}) ^{-1}[/tex] can be written as- [tex](9}) ^{1}[/tex] = 9
Thus, the expression becomes-
1/81 _ 9
clearly we can see that 1/81 < 9
Now, we have [tex](\frac{1}{9}) ^{-1}[/tex] _ [tex](\frac{1}{9}) ^{-2}[/tex]
As shown above, the expression can be simplified as-
[tex](9) ^{1}[/tex] _ [tex](9) ^{2}[/tex]
9 _ 81
clearly we can see that 9 < 81
Next, we have- [tex]9^{-1}[/tex] _ [tex]9^{-2}[/tex]
we can write this as-

How is a coordinate plane defined simply?A coordinate plane is just a two-dimensional plane that is created when two number lines cross. These number lines include the x-axis, a horizontal number line, and indeed the y-axis, a vertical number line.
The coordinate plane where is it?In a coordinate plane, which is a two-dimensional number line, the vertical line is known as the y-axis and the horizontal line as the x-axis, as you might recall from pre-algebra. These parallel lines cross one another at their zero points. The origin is where we start from.
According to the given data:Equation:

Write an equation in slope - intercept form for the line that passes through the given paint andis parallel to the given equation.(9, 12), y = 13x-4
Answers
The equation of a line is given by
[tex]y-y_1=m(x-x_1)[/tex]where m is the slope of the line and (x1,y1) is a point where the line passes through.
In our case we have a point but we don't have the slope yet, so we have to find it. To do this we have to remember that two lines are parallel if and only if their slopes are equal, that is
[tex]m_1=m_2[/tex]We know that the line we are looking for is parallel to the line
[tex]y=13x-4[/tex]we notice that this line in written in the slope-intercept form
[tex]y=mx+b[/tex]then its slope is 13.
Since the line is parallel to the one we are looking for, our slope is also 13.
Using the point (9,12) and the slope the equation of the line is
[tex]y-12=13(x-9)[/tex]now we have to write in the slope-intercept form
[tex]\begin{gathered} y-12=13x-117 \\ y=13x-117+12 \\ y=13x-115 \end{gathered}[/tex]Therefore the line is

In mathematics, a relationship between two expressions or values that are not equal to each other is called inequality.In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.Graphing inequalities is the process of showing what part of the number line contains values that will "satisfy" the given inequality. A graph of this inequality will show what numbers may be used to replace x in our inequality to make a true statement.Linear inequalities can be graphed on a coordinate plane.The solutions for a linear inequality are in a region of the coordinate plane. A boundary line, which is the related linear equation, serves as the boundary for the region.Linear inequalities are different than linear equations, although you can apply what you know about equations to help you understand inequalities.

Answers
The length of the diameter of the circle is found as the 2×(√5).
What is termed as the equation of the circle?The equation of circle offers an algebraic method for describing a circle given its center and radius length. The equation of a circle differs from the formulas used to calculate a circle's area or circumference. The standard equation for a circle with a radius r and a center at (x1,y1) is: (x−x1)²+(y−y1)²=r².,
For the given question;
The equation of the circle is given as;
(x-4)^2+(y-2)^2=5
Comparing the equation of the circle with the standard form.
Radius r² = 5
Then, r = √5

A hot air balloon is a lighter in weigh than air. It is an object made up of an envelope-like bag that holds heated air. A wicker basket, gondola, or capsule suspended below transports people and a heat source, typically an open flame produced by burning liquid propane. A capsule also carries passengers in some long-distance or high-altitude balloons.
Lets understand with the help of a right angle triangle, The point from where the hot air balloon taken off be point A, and the point where Isabelle is standing is point B, and the point where the balloon is point C.
The AB= distance between Isabelle and the point from where hot air balloon taken off = base of the imagined triangle,
AC = height at which hot air balloon is floating = perpendicular of the imagined triangle
BC = distance between Isabelle and hot air balloon = Hypotenuse of the imagined triangle
Applying Pythagoras theorem,
(BC)² = (AC)² + (AB)²
(BC)² = (20)² + (21)²
BC = 29

So we can write out the following ratios:
