[tex]( {x}^{2} + 6x + 8)( {x}^{2} + 6x + 13) =0 \\ [/tex]

_________________________________

[tex] {x}^{2} + 6x + 8 = 0 [/tex]

[tex](x + 2)(x + 4) = 0[/tex]

##############################

[tex]x + 2 = 0[/tex]

[tex]x = - 2[/tex]

##############################

[tex]x + 4 = 0[/tex]

[tex]x = - 4[/tex]

[tex]∆ = {b}^{2} - 4ac [/tex]

[tex]a = coefficient \: \: of \: \: {x}^{2} = 1 [/tex]

[tex]b = coefficient \: \: of \: \: x = 6[/tex]

[tex]c = the \: \: alone \: \: number \: = 13 \\ [/tex]

Thus ;

[tex]∆ = ({6})^{2} - 4 \times (2) \times (13) [/tex]

[tex]∆ = 36 - 104[/tex]

[tex]∆ = - 68[/tex]

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

Point :

Remember from now on ,

In quadratic functions ;

if :

[tex]∆ > 0[/tex]

The function has two roots

if :

[tex]∆ = 0[/tex]

The function has just one root

if :

[tex]∆ < 0[/tex]

The function doesn't have any root.

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

Thus , ( x² + 6x + 13 ) doesn't have any root.

So ; ( x = - 2 ) & ( x = - 4 ) are the only roots.

Step-by-step explanation:

The coefficient is the number before the degree. In this equation, it looks to be that the number before the 6th degree is 14.

Answer:

It moves the x value 5 units to the left.

Step-by-step explanation:

"x - 5" means that we are subtracting 5 to whatever x value we are given. The "y" value doesn't change.

Since we are subtracting to the x value, we are going to move left 5 units.

Let's say we had the point (5, 5).

If we use the translation rule;

(5 - 5, 5)

(0, 5)

We moved the x value 5 units to the left.

Answer:

after 2 hours, they will have the same fee.

they will have been payed 11$

Step-by-step explanation:

if you say  h = hours of tutoring,

Rakim charges 7 + 2h

Joan charges 3 + 4h

since you want them to be the same, you can write the following equation:

7 + 2h = 3 + 4h

subtract 2h from each side

7 = 3 + 2h

subtract 3 from each side

4 = 2h

divide both sides by 2.

h = 2

after 2 hours, they will have the same fee.

they will have been payed 11$

"they will have been payed" ah yes the grammar.

Answer:

42°

Step-by-step explanation:

The angle measure of 295° just means we are working with a circle.

A circle totals to 360°.

If we add what we are given; 295 + 23 = 318°

We have the total angle measure we are given and "b" which we need to solve.

We can subtract 360 by what we are given to find angle "b"

360 - 318 = 42°

Answer:

$4900

Step-by-step explanation:

It is given that,

According to health insurance policy, hospital expenses are subject to a $750 deductible and $150 per day copay.

If a person hospitalized for 4 days, it would mean that charges will be ($150 × 4 = $600 per day).

Total amount given by insurance policy = $750 + $600 = $1350

The bill for 4 days come out to be $6,250.

The person have to pay ($6,250-$1350) = $4900 itself.

Answer:

Part A - Yes; y=5/3w        Part B - No; e=h+2

Step-by-step explanation:

The tables show the numbers of white and yellow flowers Cara and Hector used in 5 different arrangements.

Cara’s Flower Arrangements            Proportional

White 3 6 9 12 15

Yellow 5 10 15 20 25

Hector’s Flower Arrangements          Not Proportional

White 4 8 12 16 20

Yellow 6 10 14 18 22

Part A

Are the numbers of white and yellow flowers in Cara’s arrangements proportional?

Which equation relates the number of white flowers, w, to the number of yellow flowers, y?

Yes; y=3/5w

Yes; y=5/3w CORRECT ANSWER

No; y=3w+5w

No; y=5+3w

Part B

Are the numbers of white and yellow flowers in Hector’s arrangements proportional?

Which equation relates the number of white flowers, h, to the number of yellow flowers, e?

Yes; e=3/2h

Yes; e=2/3h

No; e=h+2 CORRECT ANSWER

No; e=h−2

They are correct because Part A is 1.666667  thats more than 1 so it cant be the first, and Part B, its the White flowers plus 2 to be Yellow flowers, not -.

Following are the solution to the given question:

                   [tex]\bold{White (w) }\\\\\bold{Yellow (y)}[/tex]

                    [tex]\bold{y = kw } \\\\\bold{5 = 3k}[/tex]

                  [tex]\bold{White (h) }\\\\\bold{Yellow (e)}\\\\[/tex]

               [tex]\to \bold{e = h + 2}[/tex]

Answer:

2 pounds = 0.9072 kilograms

Step-by-step explanation:

Answer:

it is b

Step-by-step explanation:

Answer:

yes they are equivalent

Answer: B) No, because not all of the pairs represent the same ratio

For each row, divide y over x

Row 1:  y/x = 5/3 = 1.67 approximately

Row 2: y/x = 7.4 = 1.75

Row 3: y/x = 10/6 = 1.67 approximately

Row 4: y/x = 15/9 = 1.67 approximately

We see that row 2 has a ratio different from the others. If we were able to ignore this row, then the answer would be "yes x and y are proportional". However, we cannot ignore this row so that's why the answer is choice B.

We want to see if the relationship between x and y is proportional or not.

We will see that the correct option is B:

"No, because not all of the pairs represent the same ratio."

Let's see how to solve this.

First, a proportional relationship is something of the form:

y = k*x

Where k is the constant of proportionality.

So to see if the relationship between x and y is proportional, we can input the pairs on the general proportional relationship.

For the first pair, we have x = 3 and y = 5, then:

5 = k*3

Now we can find the value of k:

k = 5/3 = 1.667

Now let's do the same for the second pair of points, we should get the same constant of proportionality.

7 = k*4

k = 7/4 = 1.75

So we got different constants of proportionality for two different x-y pairs, thus, the relationship is not proportional.

Because k is defined as the ratio between y and x, we can say that the relationship is not proportional because not all of the pairs represent the same ratio.

Thus the correct option is B.

The required expanded form of three hundred twenty-six thousand, five hundred eight and nine hundredths, 300,000 + 20,000 + 6,000 + 500 + 80 + 0.09.

Given that,
To determine the expanded form: Three hundred twenty-six thousand, five hundred eight and nine hundredths.

A number system is described as a technique of composing to represent digits. It is the mathematical inscription for describing the numbers of a given set by using numbers or other characters in a uniform method. It delivers a special presentation of every digit and describes the arithmetic structure.

Here,
Three hundred twenty-six thousand, five hundred eight and nine hundredths = 326580.09
The expanded form of a number is the sum of the digit with the intrinsic value of the digit placed in the number,
Expanded form = 300,000 + 20,000 + 6,000 + 500 + 80 + 0.09.

Thus, the required expanded form of three hundred twenty-six thousand, five hundred eight and nine hundredths, 300,000 + 20,000 + 6,000 + 500 + 80 + 0.09.

Answer:

No

Step-by-step explanation:

19 is a prime number but 95 is not.

95= 1x95

       5x19

Step-by-step explanation:

19 is a prime number. Factors of 19 up to 100 are 19, 38, 57, 76, 95. ... Thus, there are 95 co-prime numbers to 19 exists between 1 and 100.

Answer:

(2a - 5) • (3a - 2)

step by step explanation:

Step-1 : Multiply the coefficient of the first term by the constant 6 • 10 = 60

Step-2 : Find two factors of 60 whose sum equals the coefficient of the middle term, which is -19 .

-60 + -1 = -61

-30 + -2 = -32

-20 + -3 = -23

-15 + -4 = -19 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and -4

6a2 - 15a - 4a - 10

Step-4 : Add up the first 2 terms, pulling out like factors :

3a • (2a-5)

Add up the last 2 terms, pulling out common factors :

2 • (2a-5)

Step-5 : Add up the four terms of step 4 :

(3a-2) • (2a-5)

Which is the desired factorization

Final result :

(2a - 5) • (3a - 2)
