The conjecture is always true, two right angles are always supplementary.

A pair of angles are supplementary only when the sum of those angles equals to 180°. In such a case each angle is said to be the supplement of another.

In case of parallel lines  and a transversal two co-interior angles are supplementary. The opposite angles of a cyclic quadrilateral are supplementary angles .

For two angles to be supplementary only the sum of the angles matter and they should always be 180°.

The numerical value of right angle is 90° .

Therefore the sum of two right angles will be 90°+ 90° = 180°

So the conjecture which states that two right angles are supplementary will always stand as the sum of two 90°s is always 180°.

Hence the conjecture is true.

Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100.

The number 1/3 as a percentage is 33.33 %.

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The percent sign, %, is frequently used to indicate it. There is no unit of measurement for a percentage. It is a dimensionless number (pure number).

Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the whole by the whole and multiply the result by 100 to get the percentage.

Let the number be 1/3 then

1/3 = 0.3333

To find percentage multiply it by 100, we get

So, 0.3333 × 100 = 33.33 %

Therefore, the number 1/3 as a percentage is 33.33 %.

The midpoint is at (1 , -7/2 ,1/2)

In the given statement is

To find the midpoint of the line segment joining the pair of points

Midpoint:

The coordinates of the midpoint of a line segment are the average of the coordinates of the end points.

m = (A +B)/2

If we are given three points and we wish to find the midpoint of those points, we need to use the midpoint formula m =(  [tex]\frac{x_{1}+x_{2} }{2} ,\frac{y_{1}+y_{2} }{2} , \frac{z_{1}+z_{2} }{2}[/tex] )

where:

(x1 , y1 ,z1) are the coordinates of the first point:

(x2 , y2 , z2) are the coordinates of the second point:

Now, We are given the three points G(-3,-4,6) and H(5,-3,-5)

Solving for the midpoint , we have,

m = ([tex]\frac{-3+5}{2},\frac{-4+(-3)}{2} ,\frac{6+(-5)}{2}[/tex])

The slope of the line containing (4,2) and (4,-3) is 1.

The slope of a straight line can be written as follows,

m = ( [tex]y_{2} - y_{1}[/tex])/([tex]x_{2} - x_{1}[/tex])                 equation1

The line is containing the points (5,-1) and (2,-4). So, we can write

[tex]y_{2}[/tex] = -4 , [tex]y_{1}[/tex] = -1 , [tex]x_{1}[/tex] = 5 , and [tex]x_{2}[/tex] = 2 .

On substituting the values of variables in equation1, we will get

m = (-4-(-1))/(2-5) = (-3/-3) = 1.

As the slope of a line is 1 , so we can conclude that the given line is a straight line.

Here,

m = the slope of the line

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex]  ) are the first coordinates.

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex]  )are the second coordinates.

Answer:

m = 8

Step-by-step explanation:

I looked at the line 8 and looked at m and noticed they're literally the same length. so m = 8.

The sequence  1,4,9,16, . . . is neither an arithmetic nor a geometric sequence. In fact, it is a quadratic sequence. The next two terms are: 25 and 36

Given a sequence:

  1,4,9,16, . . . .

To determine whether the sequence is an arithmetic, geometric, or neither, we need to check the relation between two consecutive terms.

Arithmetic sequence:

   a(n) = a(n-1) + d

or a(n) - a(n-1) = d  for all n

where d is a constant and is usually called common difference.

Geometric sequence:

   a(n) = a(n -1) . r

or a(n)/a(n-1) = r, for all n

In the given sequence:

a(1) = 1

a(2) = 4

a(3) = 9

a(4) = 16

Check the difference:

a(2) - a(1) = 4 - 1 = 3

a(3) - a(2) = 9 - 4 = 5

Since the difference between 2 consecutive sequence is not a constant, then the sequence is not an arithmetic one.

Check the ratio:

a(2)/a(1) = 4

a(3)/a(2) = 9/4

Since the ratio of 2 consecutive sequence is not a constant, then the sequence is not a geometric one.

Thus the given sequence is neither an arithmetic, nor a geometric sequence. In fact, it is a quadratic sequence. Notice that:

a(n) = n²

Hence, the next two terms are: 25 and 36

The equation of the line in slope-intercept form is y = 4x + 11 .

The equation of a line in slope-intercept form can be written as follows,

y = mx + c                                                       equation 1

m in the above equation represents slope of the line and c represents the intercept.

The given equation is 4x = y - 11 .

To get the equation of the line in slope-intercept form we need to convert the given equation in the format of equation of a straight line i.e., equation1. So, now we will rearrange the given equation as

4x = y - 11

On adding 11 on both sides in above equation, we will get

y = 4x + 11                                                      equation 2

On equating equation 1  and equation 2, we will get

Slope of the line = m = 4

Intercept = c = 11

Answer:  shift 2 units right, and 4 units down

==================================================

Explanation:

The x+2 means to shift the point 2 units to the right.

For instance, the point (5,13) moves to (7,13) after adding 2 to the x coordinate.

The y-4 means to shift the point 4 units down. Example: (10,8) moves to (10,4) after subtracting 4 from the y coordinate.

Overall, (x,y)→(x+2,y-4) means "shift 2 units right, and 4 units down"

------------

Example:

Let's apply the rule to the point (1, 7)

(x,y)→(x+2,y-4)

(1,7)→(1+2,7-4)

x=3 4.-3/5 + x = 12/5

x= 12/5 + 3/5

x= 15/5

5. -14x = -42

x= -42/-14

x = 42/14

Based on the calculations, the coordinates of the y-intercept are (0, -9).

In Mathematics, the y-intercept of any graph (parabola) occurs at the point where the value of "x" is equal to zero (0). Similarly, the x-intercept refers to the point at which the graph of a function crosses the x-axis and the value of "y" is equal to zero (0).

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope, m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope, m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

Substituting the given parameters into the formula, we have;

Slope, m = (-4.5 - 3)/(-3 + 8)

Slope, m = -7.5/5

Slope, m = -1.5.

Mathematically, the standard form of the equation of a straight line is given by;

y - y₁ = m(x - x₁)

At point (-8, 3), we have:

y - 3 = -1.5(x + 8)

y - 3 = -1.5x - 12

y = -1.5x - 12 + 3
