What is the solution to the linear equation?
4b + 6 = 2 - 6 + 4

Answer:

C

Step-by-step explanation:

When we set the numerator equal to 0 and solve for x, that value is the horizontal asymptote (a line the graph come towards, but never crosses).

Looking at the graph, the horizontal asymptote is x = 2, so which one of the 4 functions has a horizontal asymptote of 2? Let's check.

A) 2x - 1 = 0

x = 1/2

B) same, x = 1/2

C) 2x -4 = 0

x = 2

D) same as A,B, x = 1/2

As we can see, option C has the right horizontal asymptote and A,B,D are eliminated. So answer is C.

Answer:

A

Step-by-step explanation:

3x-5≥19

Add 5 to each side

3x-5+5≥19+5

3x ≥ 24

Divide each side by 3

3x/3 ≥24/3

x ≥8

Since this is greater than or equal to there is a closed circle at 8

greater than means the line goes to the right

Answer:

The answer is 9

Step-by-step explanation:

When you divide 54 by 6 you get 9 because 10 times 6 equals 60 so if you minus 6 you get 54 which equals 6 times 9. :)

Answer:

9 or 9/1

Step-by-step explanation:

To convert improper fractions to whole numbers, you have to divide the numerator by the denominator.

So, 54 divided by 6 is 9

So 54/6 as a whole number 9

If you want to keep as a fraction it would be 9/1

Answer:

[-∞, 3)

Step-by-step explanation:

We are given the following inequality which we are to express as a set using the interval notation:

[tex] - 2 x + 3 0 > 4 x + 1 2 [/tex]

Rearranging the inequality by adding the like terms together to get:

[tex] - 2 x - 4 x < 1 2 - 3 0 [/tex]

[tex] - 6 x < - 1 8 [/tex]

[tex]x<\frac{-18}{-6}[/tex]

[tex]x<3[/tex]

Since the values of [tex]x[/tex] are lesser than [tex]3[/tex] so we can express this in interval notation as:

[-∞, 3)

Answer:

y+1 = 2/5(x+3)

Step-by-step explanation:

We have a point and a slope so we can use point slope form

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

y--1 = 2/5 (x--3)

y+1 = 2/5(x+3)

Answer:

-6

Step-by-step explanation:

f(g(-1)) means we need to find g(-1) and then plug that result into f(x).

So let's start:

g(-1) means to replace the input variable in g(x)=x^2 with -1.

So we replace x with -1.  

g(-1)=(-1)^2

g(-1)=1

Now that we have g(-1) can be replaced with 1, we can further evaluate f(g(-1)).

So let's do that:

f(g(-1))

f(1)=1-7   ; I replaced the x in f(x)=x-7 with 1 to find f(1).

f(1)=-6

----

Putting altogether

f(g(-1))=f((-1)^2)=f(1)=1-7=-6.

Answer:

f(g(-1)) = -6

Step-by-step explanation:

* Lets explain how to solve the problem

- The problem is about the composite function

- A composite function is a function that depends on another function.

- A composite function is created when one function is substituted into

 another function.

- Ex: f(g(x)) is the composite function that is formed when g(x) is

 substituted for x in f(x)

* lets solve the problem

∵ f(x) = x - 7

∵ g(x) = x²

- We want to find f(g(-1))

* At first lets find g(-1) by substitute x in the function g(x) by -1

∵ g(x) = x²

∵ x = -1

∴ g(-1) = (-1)² = 1

* Now we want to find f(g(-1)), then we will substitute x in f(x) by

 the value of g(-1)

∵ g(-1) = 1

∵ f(x) = x - 7

∴ f(g(-1)) = f(1)

∵ f(1) = 1 - 7 = -6

∴ f(g(-1)) = -6

i have answered ur question

The Perimeter of the given polygon can be calculated using the distance formula for each of its sides. The calculated distances are added to give a total perimeter of approximately 18.5 units.

The Perimeter of a polygon is calculated by adding the lengths of all its sides. Here, we need to calculate the distance between each pair of points, which gives the length of the sides of the polygon.

The distance between two points (x1, y1) and (x2, y2) is given by the formula sqrt((x2-x1)² + (y2-y1)²) .

To find the Perimeter of the polygon, we calculate the distances between each pair of vertices and then add them up:

Adding these distances, we get a perimeter of approximately 5 + 4.1 + 3.2 + 4.2 + 2 = 18.5 units, rounded to the nearest tenth of a unit.

Step-by-step explanation:

expand the form

Answer:

x = 6, x = -5, x = 9

if f(x)=(x-6)(x+5)(x-9)

Step-by-step explanation:

The zeros of a polynomial in factored form can be found by setting the polynomial equal to zero and then realizing if a product is zero, then at least one of it's factors is zero.

So we have the zero's are the x's that satisfy

(x-6)(x+5)(x-9)=0.

We just need to solve three equations:

x-6=0

           This can be solved by adding 6 on both sides:  x=6

x+5=0

         This can be solved by subtracting 5 on both sides: x=-5

x-9=0

         This can be solved by adding 9 on both sides: x=9

The solutions are in { 6,-5,9 }.

Answer:

x = 6, x = -5, x = 9

Step-by-step explanation:

If the polynomial f(x) is written in factored form, f(x) = (x − 6)(x + 5)(x − 9), the zeros of the polynomial function are x = 6, x = -5, x = 9.

x-6=0  x = 6

x+5=0  x = -5

x-9=0  x = 9

Therefore, x = 6, x = -5, x = 9 would be the correct answer.

Let the length = x and the width = y

For the length of fence we have x +x + y = 48 = 2x +y = 48

Rewrite as y = 48 - 2x

For the area we have x * y  = 254

Replace y in the are equation:

x * 48 -2x = 254

Simplify the left side:

48x - 2x^2 = 254

Subtract 254 from both sides:

48x - 2x^2 - 254 = 0

Using the quadratic formula solve for x:

a = -2, b = 48 and c = -254

x = -48 + 4√17/-4

x = 16.123 m.

The length = x = 16.123 meters.

The width = 48 - (16.123*2) = 15.754 meters

Rounding to the nearest centimeter:

Length = 16.1 ( 16 meters and 1 cm)

Width = 15.8 ( 15 meters and 8 cm)

The answer to the question is A

first off, let's notice something, the graph seems a bit misleading, since the height of the nut is 0.5 cm, whilst the side of the base is 0.6 cm, however in the picture 0.5 appears longer.  That said

1)

the volume of the nut itself is simply the volume of a hexagonal prism, which will just be the product of the area of the hexagon and the height.

[tex]\bf \textit{area of a regular polygon}\\\\ A=\cfrac{1}{2}ap~~ \begin{cases} a=apothem\\ p=perimeter\\ \cline{1-1} a=0.5\\ p=\stackrel{0.6\times 6}{3.6} \end{cases}\implies A=\cfrac{(0.5)(3.6)}{2}\implies A=0.9 \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{volume of the hexagonal prism}}{\stackrel{\textit{hexagon's area}}{(0.9)}~~\stackrel{\textit{height}}{(0.5)}\implies 0.45}[/tex]

2)

[tex]\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} r=0.4\\ h=0.5 \end{cases}\implies V=\pi (0.4)^2(0.5)\implies V\approx 0.25[/tex]

3)

well, the composite figure is just a hexagonal nut with a cylindrical hole, so if we simply get the volume of the prism and subtract the volume of the cylindrical hole, what's leftover, is the volume of the nut alone without the hole.

[tex]\bf \stackrel{\textit{from 1)}}{0.45}~~-~~\stackrel{\textit{from 2)}}{0.25}\implies 0.20[/tex]

Answer:

4

Step-by-step explanation:

16/4 = 4

if 75% of equipment is iron then do the math.

So it would be 4(2) + 4 = 75% of 16

So if 75% of 16 is 12 you need that extra 4 to get you to 16

The number of woods are [tex]\fbox{\begin \\\math{4}\\\end{minispace}}[/tex].

Further explanation:

Consider the number of woods as [tex]x[/tex] and number of irons as [tex]y[/tex].

Since the number of irons is four more than two times the number of woods, the number of irons is calculated as follows:

[tex]y=2x+4[/tex]                                                      ......(1)

The number of equipment consists of the woods and irons, therefore, the number of equipment [tex]n[/tex] is written as the sum of number of woods [tex]x[/tex] and number of irons [tex]y[/tex] as follows:

[tex]n=x+y[/tex]                                                                  ......(2)

From equation (1), substitute [tex]2x+4[/tex] for [tex]y[/tex] in above equation.

[tex]n=x+2x+4\\n=3x+4[/tex]

Since the total equipment contains [tex]75\%[/tex] of irons, it can be written as follows:

[tex]y=0.75n[/tex]

From equation(1) and (2) substitute [tex]2x+4[/tex] for [tex]y[/tex] and [tex]3x+4[/tex] for [tex]n[/tex] in above equation.

[tex]2x+4=0.75(3x+4)\\\Leftrightarrow2x+4=2.25x+\\\Leftrightarrow4-3=2.25x-2x\\\Leftrightarrow1=0.25x\\\Leftrightarrow x=1/0.25\\\Leftrightarrow x=4[/tex]

Substitute 4 for [tex]x[/tex] in equation (1) to obtain the number of irons.

[tex]y=2(4)+4\\y=8+4\\y=12[/tex]

Thus, the number of woods are 4 and number of irons are 12.
