i need this pleaseeeee!!!!
(a) The population of a certain city decreased by 4000 people. Write a signed number to represent this population change.
and also b!!!!​

Answer:

[tex]x=13[/tex]

Step-by-step explanation:

By the definition of an angle bisector, we have that [tex]8x-23=5x+16[/tex].

We can add [tex]23[/tex] to both sides to get [tex]8x=5x+39[/tex].

We can then subtract [tex]5x[/tex] from both sides to get [tex]3x=39[/tex].

We can finally divide both sides by [tex]3[/tex] to get [tex]\boxed{x=13}[/tex]

answer

is 13.21 because i did the promble on the calculatoor

Answer:

16 times

Step-by-step explanation:

Membership cost:

C = 135 + 2x

Non-members:

C = 11x

____

135 + 2x = 11x

135 = 9x

x = 15

The cost would be the same after renting 15 times, so after 16 times the cost would be cheaper for a member.

It's A.

1. The closed circle connects to the x≥1 function, so that rules out B and C.

2. The x≥1 piece has a positive slope on the graph, so that rules out D.

Answer:

A. Acute and B. Equilateral

Step-by-step explanation:

Find the slope of the perpendicular line

When two lines are perpendicular, the product of their slopes is -1. This means that the slopes are negative-reciprocals of each other.

            ⇒  if the slope of one of the lines =  - 6

                 then the slope of the perpendicular line (m) = ¹/₆

Determine the equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

                              ⇒  y - 20 =  ¹/₆ (x - (-12))

                               ∴  y - 20 = ¹/₆ (x + 12)

We can also write the equation in the slope-intercept form (y=mx+c) like the equation in the question by making y the subject of the equation and expanding the bracket to simplify:

                          since   y - 20 = ¹/₆ (x + 12)

                                      y - 20 =  ¹/₆x + 2

                                              y =  ¹/₆x + 22

∴ the slope-intercept equation of the perpendicular line is y =  ¹/₆ x + 22.

To test my answer, I have included a Desmos Graph that I graphed using the information provided in the question and my answer.

Answer:

1/2

Step-by-step explanation:

For three coin tosses, the posible outcomes are:

[(HHH), (HHT), ( THH), (HTH), ( THT), (TTH), (HTT), (TTT)

The outcomes where there are at least 2 tails are:

(TTT), (TTH), (THT), (HTT)

So, the probability that the coin will land tails at least 2 times is 4/8 or 1/2

Step-by-step explanation:

Answer:

angle OPN, angle PON, angle NOP, angle PNO

Step-by-step explanation:

Essentially, this simply asks what angles contain the line OP. If we draw the triagnle NOP (in that order starting at the top), we can see that all these angles include the line OP within their angles.

(note: Im not sure if it is asking for the line OP in that order. If so, it would only be angles 1 and 3, as those have OP in that order)

Height / Width = 1.2in / 2.1in

Height / Width x / 84in (7feet)

Solve for X using cross multiplation

2.1x = 1.2 * 84

2.1x = 100.8

x (height) = 48 inches or 4 feet.

He is making $2.50x (x = amount of drinks sold)

Than we subtract the amount of money he lost - $15

$2.50x - $15

Hope this helps.

Step-by-step explanation:

Given the function, f(x) = -3x + 4, you basically need to choose any input (x-value) and substitute those values into the function.

       f(0) = -3(0) + 4

       f(0) = 0 + 4

       f(0) =  4 [this is the value of your final column, in the f(x)].

   2. f( 1 ) = -3( 1 ) + 4, where the input is x = 1.

       f( 1 ) = -3( 1 ) + 4

       f( 1 ) = -3 + 4

       f( 1 ) =  1 [this is the value of your final column, in the f(x)].

   3. f(2) = -3(2) + 4, where the input is x = 2.

       f(2) = -6 + 4

       f(2) = -2 [this is the value of your final column, in the f(x)].

All you need to do is plot the following points on your graph:

{(0, 4), (1, 1), (2, -2)}

Answer:

y=[tex]-\frac{3}{2}x-5[/tex]

Step-by-step explanation:

Use the point slope formula

[tex]y-y_1=m(x-x_1)[/tex]

y-1=[tex]-\frac{3}{2}[/tex](x-4)

Multiply -3/2 by (x-4) which equals -3/2x-6

Move the 1 by adding to both sides

The gives us y=[tex]-\frac{3}{2}x-5[/tex]

Answer:

Exact area = 1800 - 450pi  square cm

Approximate area = 387 square cm

I used 3.14 for pi to get the approximate value.

============================================================

Explanation:

Check out the diagram below.

As the diagram shows, the largest radius possible is half of the shortest dimension of this rectangle. So the radius of each identical circle is 30/2 = 15 cm. The radius cannot exceed this value, or else the circle will spill outside the rectangle.

The area of one circle would be

A = pi*r^2

A = pi*15^2

A = pi*225

A = 225pi

Two identical circles like this combine to a total area of 2A = 2*225pi = 450pi square cm.

The area of the brown shaded region in the figure, aka the amount of cardboard leftover, is exactly 1800 - 450pi. The 1800 is from the computation of 60*30 = 1800, which is the area of the original rectangle before we made any cuts.

If we wanted to find the approximate area, then we could use pi = 3.14 to get

1800 - 450pi = 1800 - 450*3.14 = 387

The approximate area remaining is 387 square cm. This value is approximate because pi = 3.14 is approximate. If you were to use more decimal digits of pi, then you'd get some other approximate area.
