How do you solve 3b(9b-27)=0

Answers

Answer 1

Answer:0

Step-by-step explanation:3b(-27 + 9b) = 0

(-27 * 3b + 9b * 3b) = 0

(-81b + 27b2) = 0

Answer 2

Answer:

[tex]b=3[/tex], or [tex]0[/tex]

Step-by-step explanation:

[tex]\mathrm{Using\:the\:Zero\:Factor\:Principle:\quad \:If}\:ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0[/tex]

[tex]b=0\quad \mathrm{or}\quad \:9b-27=0[/tex]

[tex]9b-27=0[/tex], [tex]\mathrm{Add\:}27\mathrm{\:to\:both\:sides}.[/tex]

[tex]9b-27+27=0+27[/tex]

[tex]9b=27[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}9[/tex]

[tex]\frac{9b}{9}=\frac{27}{9}[/tex]

6m - 8 = 1/2(-4m + 16)

Answers

Answer:

m=2

Step-by-step explanation:

6m - 8 = 1/2(-4m + 16)

Distribute

6m -8 = -2m +8

Add 2m to each side

6m-8+2m = -2m +8+2m

8m -8 = 8

Add 8 to each side

8m-8+8 = 8+8

8m = 16

Divide each side by 8

8m/8 = 16/8

m=2

Answer:

30°

Step-by-step explanation:

Remember, all the interior angles of a triangle add up to 180 degrees. Therefore, we can find the value of x by subtracting the values of the other angles from 180:

[tex]x = 180-97-53[/tex]

[tex]x=30[/tex]

Answer:

Soln:

x+53+97=180(sum of interior angle of a triangle is 180)

or,x+150=180

or,x=180-150

or,x=30

Hence, the value of x is 30.

ed made a large cube by gluing together a number of identical small cubes together

Answers

Answer:

thats cool not realy a question tho can I have brainlest

Step-by-step explanation:

Ed painted 95 faces of a large cube.

What is the Cubic equation?

Cubic equations are polynomials of degree 3. That means the maximum degree of the polynomial is three.

And the standard form of the cubic equation is;

f(x) = ax³ + bx² +cx +d, where a, b, c, and d are constant coefficients a ≠ 0.

Let's assume that the original cube that Ed made had n small cubes along each edge.

Then the total number of small cubes in the large cube is n³.

Let p be the number of faces that Ed painted.

Each small cube has 6 faces, and if a face is painted, it will not be visible after the large cube is assembled.

So the total number of unpainted faces is 6n³ - p.

When Nicole drops the cube, each small cube will be separated from the others, and all painted faces will become visible.  

So the total number of painted faces is equal to p minus the number of small cubes that don't have any painted faces, which is 45.

Therefore, we have a cubic equation:

p - 45 = 6n³ - p.

Simplifying this equation, we get:

2p =6n³ + 45

p = 3n³ + 22.5

We know that p is an integer, so 3n³ + 22.5 must be an integer.

This means that n³ must be a multiple of 2/3.

The smallest integer value of n that satisfies this condition is n = 3.

So Ed made a cube with 3 small cubes along each edge, and he painted:

the value of the cubic equation at 27,

p = 3n³ + 22.5 = 3(27) + 22.5 = 94.5 ≈ 95 faces of the large cube.

Therefore, 95 faces of the large cube.

The complete question:

Ed made a large cube by gluing together a number of small identical cubes and then he painted some of the faces of the large cube. His sister Nicole dropped the cube and it broke into the original small cubes. 45 of these small cubes didn't have any painted faces. How many faces of the large cube did Ed paint?

NO LINKS!! PLEASEE HELPP QUICK I POSTED THIS SO MANY TIMES AND NOBODY ANSWERS PLSSS HELP MEEE Write the slope-intercept inequality for the graph below. If necessary, use <=
fors or >= for >

Answers

Answer:

y ≤ -2x - 2

Step-by-step explanation:

Slope- intercept form is y = mx + b, m being the slope and b being the y-intercept.

The slope is the rise of the line over the run. We can choose two points that are exactly on the line. Let's try points (-1, 0) and (0, -2). The line slopes down, so we already know the slope is negative. From point (-1, 0), the line goes down 2 units and over 1 unit. So, the slope is -[tex]\frac{2}{1}[/tex]. We can also simply say that the slope is -2.

The line intersects with the y-axis at point (0, -2), so the y-intercept is -2.

Because the shading is on the left side of the line and the line is solid, we can tell that y is less than or equal to -2x - 2. So, the equation is-

y ≤ -2x - 2

Answers

Answer:

x-2 =0

x=2

Step-by-step explanation:

we take -2 to the anther side it becomes 2

Answer:

-2

Step-by-step explanation:

A function is a rule for working out the values y for the given values x

For example, h = 3x and y = x^2 are functions. The notation g(x) is read as g of x. g is the function. g(x) = 3x means the function of x is 3x

So, when solving to find the value of x, you must substitute x for any given value.

For example, f(x) = 10/x. Work out f(5), you must substitute the 5 into the denominatior of the fraction 10/x . This becomes 10/5, which equals to 2.

But for your question, to find the value of x, substitute x with 0

You end up with -2

An amusement park charges an entrance fee of $20 and the rides cost $4 each. Suppose you write a function for the total cost for entering the park and riding a. Number of the rides. What is the domain of the function based on the given context?

Answers

Answer:

With the information provided, you can say that the total cost is equal to the entrance fee plus the price per ride for the number of rides, which would be:

C(x)=20+4x,where:

x is the number of rides

The domain of the function refers to all the inputs that the function can have and in this case, the domain consists of all real numbers greater than or equal to zero since x refers to the number of rides and it can't have a negative number.

The parents liked clowns and had a big collection of them. They even had a special room for their collection. That night, the children were playing in this room. Many of the clowns were just statues, and some were life-size. The biggest clown sat in a small rocking chair. I started to feel more and more uneasy about this statue. I felt as though the eyes were looking at me all the time. I decided to call the parents. "I'm so sorry to bother you, but may I move this clown in the rocking chair. It's starting to scare the kids and me", I said."What clown are you talking about? I don't remember a big clown in the chair. Are you sure?" the mother asked hurriedly. "Yes, I'm sure, It's sitting right here. I'm looking at it right now", I said."Take the kids and get out of the house, now. Run to our neighbors. Call me immediately when you get there, the mother said. Frightened and confused, I took the kids and ran out. When I and the kids came to the neighbors, I called the mother. "What's wrong? Did anything happen? Are you all okay?" The mother asked. "Yes, we are fine, I said. "But you were in danger. It happened again. Soon we will be there with the police, I'll explain everything when we get there", said the mother. Later, the parents explained to me that for some time the next door there lived a neighbor who gave them problems. He was mentally ill. He heard voices. Many times he sneaked into their house and tried to kidnap the children. This time, he dressed up in a clown suit, painted his face, and waited quietly until he had the opportunity to take the children away. The parents informed the police many times. But they didn't have any proof. Now, it happened again. They thanked me, paid me, and drove me home. A science class is doing an experiment on how light affects the growth of plants.
