Answer:

a)  We get [tex]\mathbf{A+B=x^2-2x+1}[/tex]

So, Is the result of A+B is a polynomial:Yes

b) We get [tex]\mathbf{A-B=6x^3-7x^2+2x-1}[/tex]

So, Is the result of A-B is a polynomial:Yes

c)  We get [tex]\mathbf{A.B=9x^6+21x^5-18x^4+9x^3-3x^2}[/tex]

So, Is the result of A.B is a polynomial:Yes

Step-by-step explanation:

We are giving the polynomial equations:

[tex]A= 3x^2(x-1)\\B=-3x^3+4x^2-2x+1[/tex]

We need to find

a) A+B

[tex]A+B=3x^2(x-1)+(-3x^3+4x^2-2x+1)\\A+B=3x^3-3x^2-3x^3+4x^2-2x+1\\A+B=3x^3-3x^3-3x^2+4x^2-2x+1\\A+B=x^2-2x+1\\[/tex]

So, we get [tex]\mathbf{A+B=x^2-2x+1}[/tex]

So, Is the result of A+B is a polynomial:Yes

b) A-B

[tex]A-B=3x^2(x-1)-(-3x^3+4x^2-2x+1)\\A-B=3x^3-3x^2+3x^3-4x^2+2x-1\\A-B=3x^3+3x^3-3x^2-4x^2+2x-1\\A-B=6x^3-7x^2+2x-1\\[/tex]

So, we get [tex]\mathbf{A-B=6x^3-7x^2+2x-1}[/tex]

So, Is the result of A-B is a polynomial:Yes

c) A . B

[tex]A.B=3x^3(-3x^3+4x^2-2x+1)-3x^2(-3x^3+4x^2-2x+1)\\A.B=9x^6+12x^5-6x^4+3x^3+9x^5-12x^4+6x^3-3x^2\\A.B=9x^6+12x^5+9x^5-6x^4-12x^4+3x^3+6x^3-3x^2\\A.B=9x^6+21x^5-18x^4+9x^3-3x^2[/tex]

Answers

The set of points on this graph is a relation but not a function

We know that every function can be a relation but every relation cannot be a function.

A relation means the connection between the input and the output.

A function means that for every input there should only be one output.

Here, we have the data as:

(2,5), (1,2), (3,4), (3, 1), (6,5) and  (5,3)

We can say that it is a relation as for every input, there is an output.

But, it is not a function.

This is because the input 3 has 2 outputs as 1 and 4 which is not possible in a function.

Therefore, the set of points on this graph is a relation but not a function.

what is the value of x?
please help!!

Answers

Answer: 20

Step-by-step explanation:

Answer is x .= 70

Step by step

The two angles will equal 180 degrees as a complementary angle.

So your equation is

2x + 40 = 180

Solve for x

Subtract 40 from both sides to isolate x

2x + 40 - 40 = 180 - 40

2x = 140

Divide both sides by 2 to solve for x

2/2 x = 140/2

x = 70

Now check your work

2x + 40 = 180

2 (70) + 40 = 180

140 + 40 = 180

180 = 180

What are the domain and range of the function f(x) = x^2 + 5x + 4/ x+4

Answers

This is just a linear equation, then the domain is the set of all real numbers and the range is the set of all real numbers.

How to find the domain and range of the given function?

Here we have the function:

f(x) = (x^2 + 5x + 4)/(x + 4)

The numerator can be rewritten if we find the zeros:

x = (-5 ± √( 5^2 - 4*1*4))/(2*1)

x = (-5 ± 3)/2

Then the zeros are:

x = (-5 - 3)/2 = - 4

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

So the numerator can be rewritten to (x + 4)*(x + 1)

And the function is rewritten to:

f(x) = (x^2 + 5x + 4)/(x + 4) = (x + 4)*(x + 1)/(x + 4) = (x + 1)

This is just a linear equation, then the domain is the set of all real numbers and the range is the set of all real numbers.

Question Multiply. (−5 5/8)⋅(−2 1/3) What is the product? Enter your answer as a simplified mixed number in the box.

Answers

Answer:

[tex]13\frac{1}{8}[/tex]

Step-by-step explanation:

Given expression:

[tex]\left(-5 \frac{5}{8}\right) \cdot \left(-2 \frac{1}{3} \right)[/tex]

Convert the mixed numbers into improper fractions by multiplying the whole number by the denominator, adding it to the numerator of the fraction, and placing this as the numerator:

[tex]\implies -\dfrac{5 \cdot 8+5}{8} \cdot -\dfrac{2 \cdot 3+1}{3}[/tex]

[tex]\implies -\dfrac{40+5}{8} \cdot -\dfrac{6+1}{3}[/tex]

[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{b} \cdot \dfrac{c}{d}=\dfrac{a \cdot c}{b \cdot d}:[/tex]

[tex]\implies \dfrac{-45 \cdot -7}{8 \cdot 3}[/tex]

[tex]\implies \dfrac{315}{24}[/tex]

Convert the improper fraction into a mixed number:

[tex]\implies 315 \div 24 = 13\: \text{r}\:3[/tex]

[tex]\implies 13\frac{3}{24}[/tex]

[tex]\implies 13\frac{1}{8}[/tex]

Answer:

Product = 13 1/8

Step-by-step explanation:

The equation is,

→ (-5 5/8) × (-2 1/3)

Now the product of equation will be,

→ (-5 5/8) × (-2 1/3)

→ (-45/8) × (-7/3)

→ (-15 × -7)/8

→ 105/8

→ 13 1/8 {mixed fraction}

Therefore, the product is 13 1/8.

4.08 x 29.7 preferably show work

Answers

Answer: 121.176

Step-by-step explanation:

First, multiply out the decimal points. To get 408 from 4.08, multiply by a hundred. Likewise, with 29.7, multiply it by 10.

Then, do long multiplication with 408 and 297 (you get 121176 from that).

Finally, use your answer from the long multiplication and divide it by how many times you multiplied your original numbers. So, you have to divide by 100, and then also divide by 10.

From that, you get 121.176

What in mathematics is a linear equation?

There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.

GA= GENERAL ADMISSION =$10

Y= YOUTH =$8

GA+Y= 95

HELP ASAP

Answers

By solving a system of equations, we can see that each geranium costs 3 dollars.

What is the cost of one geranium?

First, let's define the two variables:

x = price of one rose bush.

y = price of one geranium

Now, with the information on the problem we can write two equations, thus, we will have a system of equations:

$122 = 14*x + 8*y

$120 = 12*x + 12*y

We want to solve that system, if we isolate x on the first equation we will get:

x = ($122 - 8y)/14

Now we can replace this on the other equation:

$120 = 12*($122 - 8y)/14 + 12*y

Now we can solve this for y.

14*$120 = 12*($122 - 8y) + 12*14*y

$1,680 = $1,464 + 72y

($1,680 - $1,464 )/72 = y = $3

Each geranium costs 3 dollars.

What is mean by Ratio?

A Ratio is a comparison of two or more numbers that indicates their sizes in relation to each other.

Now, The missing values are find as;

Ratio of Pounds to the weeks are;

In first column,

Pounds : Weeks = 10 : 4

In second column,

Pounds : Weeks = x : 1

In third column,

Pounds : Weeks = y : 7

Since, All ratio are equal.

Hence,

10 : 4 = x : 1

It can be written as,

10/4 = x / 1

After cross multiplication we get;

x = 10/4

x = 2.5

And,

10 : 4 = y : 7

It can be written as,

10/4 = y/7

After cross multiplication we get,
