What is the equation of a line that is parallel to −2x+3y=−6 and passes through the point (−2, 0)?



Enter your answer in the box.

[tex]2x = 76[/tex]

Due to alternate angles

[tex] \frac{2x}{2} = \frac{76}{2} \\ x = 38[/tex]

40°+(y-8)°+76°=180°(sum of angles in a triangle)

[tex]40 + y - 8 + 76 = 180 \\ y + 108 = 180 \\ y = 180 - 108 \\ y = 72[/tex]

ATTACHED IS THE SOLUTION.

Answer:

x = 38 ; y = 72

Step-by-step explanation:

180 = 76 + 40 + (y - 8)

180 = 108 + y

72 = y

The triangle has parallel lines, so the uppermost right angle is also 90 degrees.

90 - 76 = 14

180 = 90 + 14 + 2x

180 = 104 + 2x

76 = 2x

38 = x

Approximately 34% of people sleep more than 8.5 hours per night.

According to the Empirical Rule states for a normally distributed random variable: 68% of the measures are within 1 standard deviation of the mean, 95% of the measures are within 2 standard deviations of the mean and 99.7% of the measures are within 3 standard deviations of the mean. According to the question, Mean = 7 and Standard deviation = 1.5. Also, in the question the normal distribution is symmetric, which means that 50% of the measures are below the mean and the rest 50% are above the mean. Now, the mean is 7 and 8.5 is 1 one standard deviation above the mean. So, by the Empirical Rule, of the 50% of the measures that are above the mean, 68% are within 1 standard deviation of the mean (more than 8.5 hours). So, we get

0.5*0.68 = 0.34 which is equal to 34%.

Step-by-step explanation:

The vertical component of the force is 69.28  N and the horizontal component of the force is 40 N.

Resolution of forces is the process of separating a force into two or more pieces so that the combined effect on the body is the same as if it had been a single force. We can analyze motion individually in different directions thanks to the resolution of forces.

Given that a heavy box is pulled across a wooden floor with a rope. The rope forms an angle of 60.0° with the floor. A tension of 80.0 N is maintained on the rope.

The vertical component and the horizontal component will be calculated as:-

Vertical component = 80sin60=69.28 N

Horizontal component = 80cos60 = 40 N

Therefore, the vertical component of the force is 69.28  N and the horizontal component of the force is 40 N.

The area of Rectangle is length times of width

Let us find the areas of two rectangle larger and smaller.

Area of the larger rectangle:

60×90=5400 square feet.

Now divide the larger square area by the smaller square area:

Area of the smaller rectangle

40×50=200 square feet.

Now divide larger rectangle with smaller

5400/200 =27

27 is the ratio of the difference

The value that represents the variable x in the trapezoid is 108 degrees

From the question, the trapezoid represents the given parameter

We can see that the trapezoid is an isosceles triangle

This means that the angle x and y are congruent

The sum of angles is a trapezoid is 360 degrees

So, we have the following summation equation

x + x + 72+ 72 = 360

Evaluate the like terms

So, we have

2x + 144= 360

This gives

2x = 216

The rate of interest on the given principal is 7.5%.

Given that, simple interest = $56.25, principal = $300 and time period = [tex]2\frac{1}{2}[/tex] years.

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.

Simple interest is calculated with the following formula: S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years.

Now, 56.26 = (300 × R × 2.5)/100

⇒ 5625 = 750R

⇒ R = 7.5%

Therefore, the rate of interest on the given principal is 7.5%.

Step-by-step explanation:

The possible values of x that satisfies the given dimensions and the condition that the volume must be no more than 280 cubic feet is x = [1,5]

The dimensions of the aquarium is: 2x ft , (x -1) ft, and (x + 2) ft. Since the volume must be no more than 280 ft³, it means:

V = 2x (x - 1) (x + 2) ≤ 280

Divide both sides by 2:

x (x - 1) (x + 2) ≤ 140

x³ + x² - 2x - 140 ≤ 0

(x - 5) (x² + 6x + 28) ≤ 0

Since x² + 6x + 28 is always greater than zero then x that satisfies the above inequality is:

x - 5  ≤ 0

or x  ≤ 5

Using the interval notation, x = (-∞, 5]

However, remember that the dimension is always a positive number.

Hence,

x - 1 ≥ 0

It's a math tool for solving problems about proportion. You can relate more than 2 variables and from the proportion, it's possible to find an unknown number.

In the International System Units (SI), the standard unit for time is the second (s).  For solving any exercise, you need to know the relation between the units of the time. See below:

1h=60 min = 3600s

1 min = 60 s

Now you can solve the question from the rule of three for finding the payment in dollars.

The question gives: an each 8.33 min, the payment is 10 dollars. Thus, from this relation you can write:

First, you should convert 6h to minutes, then,

1 h ----- 60 min

6h ----- x

x=60*6=360 min

After that, you should apply the rule of three for finding the payment in dollars.

   8.33 min     -----  10 dollars.

   360 min    -------  x

8.33x=360*10

8.33x=3600

x= $ 432.2

The distance between the two cyclists changing exists 38.4 meters per second.

A differential equation in mathematics exists an equation that links the derivatives of one or more unknown functions. Applications often involve functions that reflect physical quantities, derivatives that depict the rates at which those values change, and a differential equation that establishes a connection between the three.

A differential equation in mathematics is an equation that includes one or more functions and their derivatives. The rate of change of a function at a place is determined by the derivatives of the function. It is mostly employed in disciplines like physics, engineering, biology, and others.

There exists at least a couple of ways to work this. One exists to write the equation for the distance between the cyclists and differentiate it.

d² = (3900 + 32t)² + (5200 + 24t)²

simplifying the above equation, we get

(2d)d/dt = 2(3900 + 32t)(32) +2(5200 + 24t)(24)

At t = 0,

dd/dt = (32·3900 + 24·5200)/√(3900² + 5200²)

simplifying the above equation, we get

= (124800 + 124800)/√(15210000 + 27040000)

= 249600/6500 = 38.4 meters per second

Therefore, the distance between the two cyclists changing exists 38.4 meters per second.

In order to determine the true statements, we would substitute the value of x and y into the given linear equation and then evaluate. From the information provided, the constraints in this situation are modeled or represented by this linear equation:

2x + 0.50y = 120

Where:

When x = 40 and y = 60, we have:

2x + 0.50y = 120

2(40) + 0.50(60) = 120

80 + 30 = 120

110 ≠ 120 (Not a solution).

When x = 30 and y = 120, we have:

2x + 0.50y = 120

2(30) + 0.50(120) = 120

60 + 60 = 120

120 = 120 (True solution).

Therefore, if we buy 30 pounds of beans we can buy with 120 pounds of rice.

When x = 0 and y = 240, we have:

2x + 0.50y = 120

2(0) + 0.50(240) = 120

0 + 120 = 120

120 = 120 (True solution).

Therefore, if we buy no beans we can buy 240 pounds of rice.

When x = 0 - 5 and y = 240 + 20, we have:

2x + 0.50y = 120

2(0 - 5) + 0.50(240 + 20) = 120

-10 + 130 = 120

120 = 120 (True solution).

Therefore, if we buy 20 more pounds of rice, we would have to buy 5 less pounds of beans.

When x = 0 + 10 and y = 240 - 60, we have:

2x + 0.50y = 120

2(0 + 10) + 0.50(240 - 60) = 120

20 + 90 = 120

110 = 120 (Not a solution).

The equation of the required perpendicular line is x + 3y = 24.

What is the slope relation for two perpendicular lines?
For two perpendicular lines on a plane, the product of their slopes always equals (-1).
What is the equation of line with slope 'm' and passing through the point (x₁, y₁)?
The standard equation of the line with slope 'm' and passing through the point (x₁, y₁) is y - y₁ = m(x - x₁).

Given, the required line is perpendicular to line given by y = 3x + 5 with slope, m₁ as 3, on analysis with standard equation of line; also the line passes through the point (9, 5) i.e. (x₁, y₁).
Let the slope of the required line be = m₂
As per statement established in the literature above, we have:
Slope of two perpendicular lines = -1
∴m₁ × m₂ = -1 ⇒ 3m₂ = -1 ⇒ m₂ = (-1)/3
Again, equation of the required perpendicular line is:
y - 5 = [(-1)/3][x - 9] ⇒ 3y - 15 = 9 - x ⇒ x + 3y = 24
