What Form is 3x + 4y = 12 in?

A. Standard Form

B. Slope-Intercept Form

C. Point-Slope Form

D. General Form

Answer:

k = - 2

Step-by-step explanation:

( 2x - y )²

Formula : -

( a - b )² = a² + b² - 2ab

Here,

a = 2x

b = y

( 2x - y )²

= ( 2x )² + y² - 2 ( 2x ) ( y )

= 4x² + y² - 4xy

So,

( 2x - y )² = 4x² + y² - 4xy

( 2x + y )²

Formula : -

( a + b )² = a² + b² + 2ab

Here,

a = 2x

b = y

( 2x + y )²

= ( 2x )² + y² + 2 ( 2x ) ( y )

= 4x² + y² + 4xy

So,

( 2x + y )² = 4x² + y² + 4xy

( 2x - y )² - ( 2x + y )²

= 4x² + y² - 4xy - ( 4x² + y² + 4xy )

= 4x² + y² - 4xy - 4x² - y² - 4xy

= 4x² - 4x² + y² - y² - 4xy - 4xy

= 0 + 0 - 8xy

= - 8xy

( 2x - y )² - ( 2x + y )² = 4xyk

- 8xy = 4xyk

Divide 4xy on both sides,

- 8xy / 4xy = 4xyk / 4xy

- 2 = k

k = - 2

Therefore, the value of k is - 2.

Answer:

n=25

Step-by-step explanation:

Using the relation that describes the measure of the angle formed by two secants being equal to half of the difference of the 2 arcs (large arc-small arc) we can establish the relation;

[tex]10 = \frac{45 - n}{2} [/tex]

[tex]20 = 45 - n[/tex]

[tex] - 45 + 20 = - n[/tex]

[tex] - 25 = - n[/tex]

[tex]n = 25[/tex]

Answer:

7m² - 11m - 2

Step-by-step explanation:

(4m² - m + 2) - (-3m² + 10m + 4)

4m² + 3m² - m - 10m + 2 - 4

7m² - 11m - 2

Answer:

10

Step-by-step explanation:

The absolute value function always gives a positive value, that is

| - a | = | a | = a

Given

| 3f - 2g |  + 2 ← substitute f = - 2 and g = 1

= | 3(- 2) - 2(1) | + 2

= | - 6 - 2 | + 2

= | - 8 | + 2

= 8 + 2

= 10

Answer:

  3/10 lb

Step-by-step explanation:

The amount needed for a fraction of a pie is that fraction times the amount needed for the whole pie:

  (4/5) × (3/8 lb) = (4·3)/(5·8) lb = (3/5)(4/8) lb = 3/(5·2) lb

  = 3/10 lb

Mr. Anderson would need 3/10 pounds of apples for 4/5 of an apple pie.

Answer:

1 and 4

Step-by-step explanation:

All you need is 2 numbers that are less than 8

Explanation:

Consider the point (1,2). If we apply the rule [tex](x,y) \to (-x,y)[/tex], then it would move to (-1,2).

The x coordinate flipped in sign from positive to negative. The y coordinate stays the same.

Another example is (-3,7) reflecting to (3,7).

Using a system of equations, it is found that Kayla will pay $54.25 for 5 adult tickets and 4 children tickets.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

Amy bought 2 adult tickets and 4 children tickets for $35.50, hence:

2x + 4y = 35.50

x + 2y = 17.75

x = 17.75 - 2y

Jane bought 3 adult tickets and 3 children tickets for $36.0, hence:

3x + 3y = 36

x + y = 12

From the first equation:

17.75 - 2y + y = 12

y = 5.75.

x = 17.75 - 2 x 5.75 = 6.25.

Hence the total paid for Kayla is given by:

T = 5 x 6.25 + 4 x 5.75 = $54.25.

Answer:

[tex]\% = 53.8 \%[/tex]

Step-by-step explanation:

Given

[tex]Yes = 483[/tex]

[tex]No = 807[/tex]

[tex]Maybe = 210[/tex]

Required

Determine percentage of "No"

First, we need to determine the total population

[tex]Total= 483 + 807 + 210[/tex]

[tex]Total= 1500[/tex]

Percentage of No is then calculated as follows:

[tex]\% = \frac{No}{Total} * 100\%[/tex]

[tex]\% = \frac{807}{1500} * 100\%[/tex]

[tex]\% = \frac{80700}{1500} \%[/tex]

[tex]\% = 53.8 \%[/tex]

therefore,this has no solutions

Answer:

1)The dependent is the number of cars produced. The independent is the amount of time

2)I know that the number of cars produced is the dependent because it will change whenever the amount of time changes

3)This relationship is linear because as you get more time, you will get more cars

4)I could create a graph because I could plot down these points and find the slope

5) I would need a couple more points to plot

p=3829.39

ur welcome

Answer:

p = 10

Step-by-step explanation:

10p - 3 = 2(12 + 4p) - 7

First, distribute within the parenthesis

10p - 3 = 24 + 8p - 7

Combine like terms

10p - 3 = 17 + 8p

Subtract 8p from both sides of the equation

2p - 3 = 17

Add 3 to both sides of the equation

2p = 20

Divide both sides by 2 to get your answer:

p = 10
