Answer:

64 = x

Step-by-step explanation:

The angles are alternate interior angles and alternate interior angles are equal when the lines are parallel

128 = 2x

Divide each side by 2

128/2 = 2x/2

64 = x

Answer:

x = 64

Step-by-step explanation:

We know that,

If lines are parallel, the alternate angles are also equal.

Therefore,

[tex] \sf2x = 128[/tex]

Now, let us solve for x.

For that, divide both sides by 2.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles. The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of intersecting curves.

Angle can also refer to the length of a rotation or an angle. This metric represents the relationship between a circular arc's length and radius. The arc is centered at the vertex and defined by the sides in the case of a geometric angle. When there is a rotation, the arc is defined by any other point and the rotation's image, and it is centered at the rotation's center.

The transformation that took f(x) = 3x+1 to g(x) = −3x−5 is reflection and translation 4 units downwards

given data

f(x) = 3x+1

g(x) = −3x−5

Reflection

Answer:

Either of ...

Step-by-step explanation:

You want the transformations that take f(x) = 3x+1 to g(x) = -3x-5.

The x-term of the transformed function has a sign opposite that of the original function. That can be accomplished by either of (a) reflection across the y-axis (replaces x by -x), or by (b) reflection across the x-axis (replaces f(x) by -f(x)).

Either way, an additional translation is required. That translation can be either vertical or horizontal, and may be done either before or after the reflection.

Reflecting f(x) across the y-axis means it becomes ...

  f(-x) = 3(-x) +1 = -3x +1

In order to make that into -3x-5, we must add -6 to the function value:

  g(x) = f(-x) -6 = (3(-x)+1) -6 = -3x -5

F(x) will be taken to g(x) = -3x-5 by reflection across the y-axis and translation down 6 units.

Reflecting f(x) across the x-axis means it becomes ...

  -f(x) = -(3x +1) = -3x -1

In order to make that into -3x-5, we must add -4 to the function value:

  g(x) = -f(x) -4 = -(3x +1) -4 = -3x -5

F(x) will be taken to g(x) = -3x-5 by reflection across the x-axis and translation down 4 units.

__

Additional comment

As noted above, the translation can be either horizontal or vertical. For example, translating the function 2 units to the right makes it f(x-2). Then reflection across the y-axis replaces x by -x, so we have ...

  g(x) = f(-x-2) = 3(-x-2)+1 = -3x -6 +1 = -3x -5

To get g(x), we could translate right 2 units, then reflect across the y-axis.

We also note that point (-1, -2) is shared by f(x) and g(x), so reflection horizontally across the line x=-1, or vertically across the line y=-2 would also give the required transformation.

Amount of money the company expected to pay = $10400

What is expectation?

At first it is important to know about probability of an event.

Probability gives us the information about how likely an event is going to occur

Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.

Suppose x is a random variable with the probability function f(x). suppose [tex]x_1[/tex], [tex]x_2[/tex],....., [tex]x_n[/tex] are the values corrosponding to the actual occurance of the event and [tex]p_1,[/tex] [tex]p_2,[/tex]....,[tex]p_n[/tex] be the corrosponding probabilities.

Expectation is given by the formula

Option B is the correct answer.

The variable represents time. The time in which a person runs a mile will depend on the speed of that person, and that can take almost any value, thus, here the variable is continuous.

First, when a variable is discrete and when it is continuous?

A variable is discrete if it only can take some selected values on a given interval, while a variable is continuous if it can take any value (or at least a dense set) of values in that interval.

For example, the numbers that one can roll on a dice form a discrete set, because the values can only be {1, 2, 3, 4, 5, 6}, just to given an example.

Now, in this case, the variable represents time. Time almost always is a continuous variable, in this case, the time is the time in which a person runs a mile. So that variable can take almost any value (depends on the speed of the person).

So we conclude that this is a continuous variable.

The equations will be a+ y ≤ 13, since Micaela can't work more than 13 hours and also she needs to earn at least $140 each week, so other equation will be 13a + 10y ≥ 140.

Inequality, a declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.

a = number of hours spent tutoring

y = number of hours spent landscaping

Micaela can't work more than 13 hours, so a + y ≤ 13.

Also, she needs to earn at least $140 each week, so 13a + 10y ≥ 140.

Using intercepts, you may graph things in this format on paper. They must be transformed into slope-intercept form in order to be graphed on a standard graphing calculator.
