Which of the following shows the quadratic formula correctly used to solve the
polynomial equation 3x^2 - 2 =11x

Answers

Answer 1

[tex]3{x}^{2} - 2 = 11x \\ + 11x \: \: \: \: \: \: + 11x \\ 3 {x}^{2} + 11x- 2 = 0 \\ quadratic \: formula \: goes \: fom \: this \: : a {x}^{2} + bx + c = 0 \\ to \: this : x = \frac{- b \ \frac{ + }{ \: } \: \sqrt{ {b}^{2} - 4ac } }{2a} [/tex]

so now you just plug in the numbers to their corresponding letter:

[tex]x = \frac{ - 11 \frac{ + }{ \: } \sqrt{ {11}^{2} - 4(3)( - 2)} }{2(3)} [/tex]

If 3/4=x/16, then x =

Answers

Answer:

12

Step-by-step explanation:

We can try and get both sides to have a common denominator. If we multiply the left side by 4, we get 12/16=x/16. Here, it is clear that x=12.

Answer:

x is equal to 12/16

Step-by-step explanation:

If you divide 12/16 by 4 you will realize that it is equal to 3/4. Therefore x is equal to 12. That is a really explanation, but hope it helps!

If the fifth term of an arithmetic sequence is 11 and the common difference is​ 4, then the sixth term of the sequence is​ _______.

Answers

Answer:

15

Step-by-step explanation:

11+4=15

The sixth term of an arithmetic sequence with fifth and common difference of 11 and 4 respectively is 15

Arithmetic sequence formula

aₙ = a + (n - 1)d

where

a = first termd = common differencen = number of terms

Therefore,

11 = a + 4d

d = 4

Hence,

11 = a + 4(4)

11 = a + 16

a = 11 - 16

a = -5

Therefore, the sixth term is as follows

a + 5d = a₆

-5 + 5(4) = a₆

a₆ = -5 + 20

a₆ = 15

9. The Osbornes have an annual income of $66,000 and monthly expenses of $5300, and they
are trying to determine whether or not they qualify for Chapter 7 bankruptcy. Their annual
income is greater than that of the median annual income of their state, but they still may be
eligible according to the means test. Help the Osbornes through the steps of the means test to
see if they qualify.
Part I: What is the Osbornes' monthly income?
I
Part II: What is the Osbornes' monthly income minus monthly expenses?
Part III: What is 60 times the answer to Part II?
Part IV: Is the answer to Part III greater than or less than $10,000?
Part V: Are the Osbornes eligible for Chapter 7 bankruptcy according to the means test?

Answers

A family qualifies for bankruptcy if the difference between their monthly income and expenditure, multiplied by 60 is greater than $10,000. So, The Osbornes qualify for chapter 7 bankruptcy.

We have the following parameters:

[tex]Annual\ Income = \$66000[/tex]

[tex]Monthly\ Expenses = \$5300[/tex]

To calculate the monthly income, we simply divide the annual income by 12 (12 is the number of months in a year)

So, we have:

[tex]Monthly\ Income = \$66000 \div 12[/tex]

[tex]Monthly\ Income = \$5500[/tex]

The difference between the monthly income and the expenses is:

[tex]Difference = Monthly\ Income - Monthly\ Expenses[/tex]

[tex]Difference = \$5500 - \$5300[/tex]

[tex]Difference = \$200[/tex]

The above result multiplied by 60 is:

[tex]Product = Difference \times 60[/tex]

[tex]Product = \$200 \times 60[/tex]

[tex]Product = \$12000[/tex]

$12000 is greater than $10000

Since $12000 is greater than $10000, then they are eligible for chapter 7 bankruptcy.

someone, please help !! these are direct and inverse variations, algebra 2. i need them asap !

Answers

Answer:

3, 20, 2, and 2.5

Step-by-step explanation:

For each question, they gave you an x and y value. If you substitute them into the equation and then solve for k, you get your answer.

On the first one, x is 12 and y is 1/4. If you put those into the equation they gave you y = k/x, you get 1/4 = k/12

3/12 is 1/4 so the first k is 3.

Second one y = k/x. x is 4 and is 5. So 5 = k/4

20/4 is 5, so the second k is 20.
