15.839 rounded to the nearest tenth is 15.8. This is because when we round it to the nearest hundredth it becomes 15.84 and then to the tenth it becomes 15.8, since 4 is less than 5.

Answer:

15.839 redondeado a la décima más cercana es 15.8.

Step-by-step explanation:

Esto se debe a que cuando lo redondeamos a la centésima más cercana se convierte en 15.84 y luego a la décima se convierte en 15.8, ya que 4 es menor que 5.

To find the population 8 years ago, we can set up an equation and solve for the original population. The population 8 years ago was approximately 37,000 people.

To find the population 8 years ago, we need to calculate the original population before the 35% increase. Let's assume the population 8 years ago was P.

Since the population has increased by 35% over the last 8 years, we can set up the equation: P + 0.35P = 50100

Simplifying the equation, we have: 1.35P = 50100

Divide both sides of the equation by 1.35 to solve for P: P ≈ 37000

Therefore, the population 8 years ago was approximately 37,000 people.

Answer:

it would be Y= -2x+4

Step-by-step explanation:

To begin, we know that the b value is 4, because that is the x-intercept that is information given, so we can atomatically put that in.

Next we need to find the m value, which can be found by knowing the rules of a perpendicular eqution. to change it you must change the 1/2 and flip the equation and change the signs

soooooo  1/2 would change into 2/1   which is 2 and we would addd the negative sign so

Y=-2x+4

Answer:

the desired equation is y = -2x + 8.

Step-by-step explanation:

Given a line with slope 1/2, we find the negative reciprocal of that to obtain the slope of a line perpendicular to the given line:  m = -2.

Recall that at an x-intercept, y = 0.  Here we're told that the x-intercept is (4, 0).  Therefore, y = mx + b becomes 0 = -2(4) + b, or b = 8.

Then the desired equation is y = -2x + 8.

Answer:

a. The ordered pair is (2 , 18)

b. The number of people jogging in year 2002 was 18 millions

c. There will be 39 millions joggers in year 2023

Step-by-step explanation:

* Lets explain how to solve the problem

- The equation y = x + 16 represents the number of people jogging

   in millions from year 2000 to 2009 where y is the number of people

   and x is the number of years after 2000

- That means at year 2000 the value of x = 0 and the number of people

   jogging was 16 millions

- The equation represented graphically by line

a.

- The ordered pair (2 , ?) means x = 2 and we need to find y when x = 2

- Substitute x by 2 in the equation

∵ y = x + 16

∵ x = 2

∴ y = 2 + 16 = 18

* The ordered pair is (2 , 18)

b.

∵ y represents the number of people jogging in millions

∵ x represents the number of years from year 2000

- That means the number of people jogging in year 2002 was 18

  millions

* The meaning of the answer of part (a) is :

  The number of people jogging in year 2002 was 18 millions

c.

-  If this trend​ continues means the equation will be the same for years

   after 2009

∵ In year 2023 ⇒ x = 23

∵ y = x + 16

∴ y = 23 + 16 = 39

* There will be 39 millions joggers in year 2023

The sale price of an item with a 33% discount is calculated by subtracting 33% of the list price from the list price itself. The equation for such a calculation is Sale Price = L - (33/100)*L.

The question is dealing with the calculation of a discount on an item's list price. When an item has a list price 'L' and the discount rate is 33%, you would calculate the sale price by subtracting 33% of the list price (L) from the list price itself. It is given by the equation Sale Price = L - (33/100)*L. This calculation will give you the final price that needs to be paid for the item after the application of the discount.

To find the value of the rational number, set up an equation using the representation of the integer as 10 times the difference of the rational number and 5. Solve the equation to find the value of the rational number, which is 17.4.

To find the value of the rational number, we can use the given equation: An Integer = 10 times the difference of the rational number and 5.

Let's denote the rational number as x. According to the equation, the integer can be represented as 10(x - 5).

Since the value of the integer is 124, we can set up the equation: 10(x - 5) = 124.

Solving for x, we can divide both sides of the equation by 10 to isolate x: x - 5 = 12.4.

Finally, add 5 to both sides to find the value of x: x = 17.4.

Therefore, the value of the rational number is 17.4.

f = 40 + 20 => f = 60.

f = 30 + 50 => f = 80.

y2 = y/x

y1 = 1

x2 = 1/y

x1 = 1/x

Formula

m = (y2 - y1) / (x2 - x1)

Solution

m = (y/x - 1) / (1/y - 1/x)

m = ( (y - x)/x ) / ((x - y)/xy)

m = (-(x - y) / x) / ( (x - y) / xy)

Invert the denominator and multiply

m = ( - (x - y) / x ) * x*y / (x - y)      Notice x - y cancels.

m = ( - 1 / x ) * (x*y)                        Notice the xs will cancel.

m = ( - 1 / y)                                   There are no xs anywhere. The slope is - 1/y

Answer: Hello there!

If you have the set of points (x1, y1) and (x2, y2), the slope of the segment whit this endpoints is:

[tex]a = \frac{y2 - y1}{x2 - x1}[/tex]

Now, we have the endpoints (1/x, 1) and (1/y, y/x), the slope of this segment is:

[tex]a = \frac{y/x - 1}{1/y - 1/x}[/tex]

Let's simplify it:

[tex]\frac{y/x - 1}{1/y - 1/x} = \frac{(y-x)/x}{(x - y)/x*y} = \frac{\frac{y-x}{x} }{\frac{-(y-x)}{y*x} }= y*\frac{\frac{y-x}{x} }{\frac{-(y-x)}{x} }  = y*(-1) = -y[/tex]

Then the slope of the segment is a = -y, and it does not depend of x

Answer:

7.3 in

Step-by-step explanation:

area = 27 = 54/2 = (x^2)/2

so what squared is 54?

7.34 whatever inches.

round it down, that's 7.3.

Answer: 7.3 in

Step-by-step explanation:

To find the the value of x, we will simply use the formula of area of a triangle, substitute the values and then solve.

From the diagram above, the height of the triangle is x and also the base of the triangle is also x, the area of the triangle is  27 sq. in

Area of a triangle =  [tex]\frac{1}{2}[/tex]  base × height

              27             =  [tex]\frac{1}{2}[/tex]   ×   x ×  x

              27               = [tex]\frac{1}{2}[/tex]   ×       x²

                27              =    [tex]\frac{x^{2} }{2}[/tex]

          cross  multiply

                    2   ×  27   =  x²

                        54    =    x²

Take the square roots of both-side

                    √54       =       √x²

                      7.3        =         x

                       x         =       7.3

Therefore the value of x is 7.3 in.

Answer:

A.

Explanation:

Just plug in the points to each equation.

A.  x + 2y = 2

Plugging in (-6,4) (-6) + 2(4) = 2 ---> -6 + 8 = 2

Plugging in (2,0)  (2) + 2(0) = 2 ---> 2 + 0 = 2

B. 2x + y = -16

Plugging in (-6.4)  2(-6) + (4) = -16 ---> -12 + 4 = -16 --> -8 [tex]\neq -16[/tex]

Because the first point didn't work there is no need to check the second one.

C. x + 2y = -8

Plugging in (-6,4)  (-6) + 2(4) = -8 ---> -6 + 8 = -8 --> 2[tex]\neq -8[/tex]

Again, because the first point didn't work there is no need to chek the next.

D. 2x + y = 4

Plugging in (-6,4)  2(-6) + (4) = 4 ---> -12 + 4 = 4 --> -8[tex]\neq 4[/tex]

Even though the answer was A. you should still check each on of them because there can always be a mistake in your work.

Answer:

A

Step-by-step explanation:

To find the equation of a line, the first thing that must be determined is the lines gradient. This can be determined by using the formula:

m = (Δy) / (Δx)

m = (4-0) / (-6-2)

m = 4 / -8

m = -0.5

The gradient has been determined, now we determine the y-intercept by using a point it passes through (either point cant be used because the line will pass through bother coordinates given)

y = mx + c       (Using the point (2,0))

0 = (-0.5)(2) + c

c = 1

Since we have the y-intercept, a formula can be created for the line, and rearranging it, we can then find the correct option.

y = mx + c

y = (-0.5)x + 1

2y = -x + 2

x + 2y = 2
