Step-by-step explanation:

Given, two straight lines intersect each other in such a way that one of the angles formed measure 90°.

We know that, lines which intersect to form a right angle are known as perpendicular lines

In the above figure , AB is perpendicular to CD

Considering ∠AOC=90°

Now,

∠AOC+∠AOD=180°     [Linear pair]

90°+∠AOD=180°

∠AOD=90°

Similarly,

∠AOC+∠BOC=180° and ∠BOD+∠AOD=180°   [Both making linear pair]

So, we get ∠BOC=90° and ∠BOD=90°

Hence, ∠AOC=∠AOD=∠BOC=∠BOD=90°

I believe it would be x = -5.

The center of dilation is outside figure A

In this question, rectangle A is dilated to rectangle B.

We know that, the center of a dilation is nothing but a fixed point about which all points are expanded or contracted.

We can observe that B = 1/2 * A

This means, the scaling factor is k = 1/2

Let's determine the center of dilation:

P'(x, y) = O(x, y) + k · [P(x, y) - O(x, y)]

Where:

O(x, y) - Center of dilation.

k - Scale factor

P(x, y) - Original point

P'(x, y) - Resulting point

(3, 1) = O(x, y) + 1/2 [(6, 2) - O(x, y)]

(3, 1) = O(x, y) - 1/2 O(x, y) + (3, 1)

1/2O(x, y) = (0, 0)

so, the center of dilation is the origin (0, 0)

So, in this case the center of dilation is outside figure A.

Therefore, the center of dilation is outside figure A

The parallel line of y=-1/2x-2 is y=-1/2x

Slope-intercept form y=mx+b of linear equations the slope-m and the y-intercept -b of a line,

here y=-1/2x-2 slope of the linear equation is m=-1/2,

whereas the y-intercept is b=-2,

Parallel lines are those lines that are equidistant from each other, the condition for representing two lines is parallel their slopes should be equal or the same.

here slope of the line is -1/2, and the fundamental equation of a line in slope intercept form is y=mx+b, taking the assumption the parallel line is passing through the origin hence the y-intercept of the parallel line is 0, b=0.

What is a function?

A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.

The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.

Given f(x)= -4x-2

g(x)=2x²+4x-5

For (f-g)(x) = -4x-2+2x²+4x-5

=2x²-9

(f-g)(x) = 2x²-9

Hence, The addition of the given two functions will be (f · g)(x) = 2x²-9

The equation of the line which is parallel to the other equation is;

[tex]y + \frac{5x}{7} +\frac{10}{7} =0[/tex].

What is the Relation between two Parallel Lines?

To determine whether two lines are parallel or not, apply the parallel line's formula. When we have the slope of two lines that we want to compare, the parallel line formula can be used. The separation between the parallel lines remains constant. Parallel lines are those that never cross each other. Since the two lines are equal in this situation and the angle is 180 degrees, they will never intersect.

In the given equation, we have:

The equation of the line is y = -5/7x-10.

and, Line k, which is parallel to the line of the equation :

[tex]y = \frac{-5x}{7} -10.[/tex]

[tex]y + \frac{5x}{7} +10. =0[/tex]

So, the equation of the line which is parallel to the line of the equation is:

[tex]y + \frac{5x}{7} +k. =0[/tex]

and since the two lines are parallels

So, the slope of equation 1 and the slope of equation two will be the same;

Also, It is given that the line includes the point  (-9, 5).

So,

[tex]5 + \frac{5 \times -9}{7} +k. =0[/tex]

⇒[tex]k = -\frac{5 \times -9}{7} -5[/tex]

⇒[tex]k = \frac{10}{7}[/tex]

So, The equation of the line which is parallel to the other equation is;

[tex]y + \frac{5x}{7} +\frac{10}{7} =0[/tex].

Hence,

The equation of the line which is parallel to the other equation is;

[tex]y + \frac{5x}{7} +\frac{10}{7} =0[/tex]..

The declaration that shows that the provided variables exist is a mathematical equation. When describing the scenario in this circumstance, two or more factors are taken into account.

The equation can be used to symbolize the price, y: Y is equal to 3 plus 2 times the weight of the package, x.

Another choice is for the buyer to pay a one-time price of $17, which is represented by the equation y = 17, in order to send the package.

We have 128 teams.

In each round, half of the teams remain, so if T is the number of teams and n is the number of rounds, we have:

and we start with n=0 so T(0)=128.

Then, we can use this recursive expression to find T after four rounds (n=4), but it is better if we derive an explicit formula for T in function of n (and not in function of the past terms of the sequence):

With the last expression we can calculate T for any value of n. Then, for n=4, we have:

Step-by-step explanation:

First of all it's important to note that all parallelograms, rhombuses and squares are quadrilateral and they meet the following properties:

- Rhombus: quadrilateral whose four sides have the same length.

- Parallelogram: quadrilateral that has two pairs of parallel sides.

- Square: quadrilateral whose four sides and internal angles have the same length/measure.

With these definitions in mind we can solve the True or False table in the picture.

The first statement is false not every quadrilateral is a rhombus. For example rectangles that are not squares are not rhombuses since their four sides aren't all equal.

The second is true, as we saw before parallelograms are quadrilaterals. The same reason applies to the third statement, squares are qudrilaterals.

Now let's see the last statement. A rhombus with four right angles is a quadrilateral that has four equal sides (because it's a rhombus) and four equal angles (all measuring 90°). These are the conditions required for a quadrilateral to be considered a square so this last statement is true.

A scale factor of 0.1  was used to create the printed photo of the sandbox

A scale factor is the size by which a shape is enlarged or reduced. It is used in increasing or reducing the size of a 2D shape, such as circle, triangle, square, rectangle, hexagon, etc.

Given that: Tess builds a sandbox in the shape of a regular hexagon in which all the sides are 40 inches long, and in the photo, the sides of the hexagon are each 4 inches long

The scale factor will be:

4/40 = 1/10 = 0.1

This means the sandbox has been reduced by 10 times the original size

Therefore, the scale factor that was used to create the printed photo of the sandbox is 0.1
