  The photo and poster of known dimensions are similar figures at a ratio of 4.

A proportion is a value that allows us to know variable values of a set of elements that are related by means of a constant.

  If we want to know if these two figures are similar or proportional, they must be at a ratio, (both dimensions), for this we formulate the following:

 This will generate an equation:

Step-by-step explanation:

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)

(1,7)→(3,3)

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

G(-3,-4,6) and H(5,-3,-5)

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])

m = (1 , -7/2 ,1/2)

Therefore, the midpoint is at (1 , -7/2 ,1/2)

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.

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

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 %

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.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. [1] The letter m is frequently used to represent slope; the reason for this usage is unclear, although it can be found in O'Brien's (1844)[2] and Todhunter's (1888)[3] formulations of the equation for a straight line as "y = mx + b" and "y = mx + c," respectively.

We have to simplify the expression.

A mathematical expression can be simplified by replacing it with an equivalent one that is simpler (often shorter), for example. Algebraic expressions are simplified in computer algebra. Logic optimization involves the simplification of Boolean expressions.

Now simplify:

9w – 4y – 8w + 1 + y – 12 – 2w

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

y = -1.5x - 9

Step-by-step explanation:

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
