Answer:

x = ⅔

Step-by-step explanation:

step 1

add -4 to both left hand side and right hand side

then you get the equation : | 3x-2| = 0

step 2

you solve the absolute value which is: | 3x-2 |

and that is : 3x-2 = 0 (possibility 1)

3x-2 +2 = 0 +2 ( add 2 to both sides )

then you get : 3x = 2

step 3

you divide 3 on both side : 3x by 3 = ⅔ ( 2 by 3)

then you get your answer as : x = ⅔

Answer:

2

Step-by-step explanation:

The equation that is perpendicular to the line is x = -1

The line equation is given as

y = 3

The point is also given as:

(x, y) = (-1, 3)

A linear equation is represented as

y = mx + c

Where m represents the slope

This means that y = 3 can be represented as

y = 0x + 3

So, the slope is 0

Since the slope is 0, the equation of the perpendicular line must be

x = xt

Where

(xt, y) = (-1, 3)

By comparison, we have

x = -1

Hence, the equation that is perpendicular to the line is x = -1

Step-by-step explanation:

1.

OA/OD = 36/64 = 9/16

OB/OC = 27/48 = 9/16

m<AOB = m<COD

triangle AOB ~ trianlge DOC

m<BAO = m<CDO

AB || CD

2.

AB/CD = OA/OD

AB/80 = 36/64

AB/80 = 9/16

16AB = 9 × 80

AB = 9 × 5

AB = 45

AB = 45 cm

3.

AB = 45

BC = OC + OB = 48 + 27 = 75

AB² + AC² = BC²

45² + AC² = 75²

AC² = 5625 - 2025

AC = √3600

AC = 60 cm

hauteur = 5 × 2 cm + 4 × 60 cm

Answer:

How do you explain a linear equation?

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of linear equation is y=mx + b. "Linear equation."

Step-by-step explanation:

In mathematics, a linear equation is an equation that may be put in the form where are the variables, and are the coefficients, which are often real numbers. The coefficients may be considered as parameters of the equation, and may be arbitrary expressions, provided they do not contain any of the variables.

Answer:

B) <

Step-by-step explanation:

Since both numbers are being multiplied by 10^-5, we can completely cut that part out of the inequality and instead just compare the values 3.2 and 4.6. It is obvious when looking at the problem that 3.2 is smaller than 4.6, so we will use the less than symbol <.

Hopefully that's helpful! Good luck on your quiz. :)

Answer:

D

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Yes, there is a continuous utility function that represents a rational preference relation when it is both continuous and monotone.

In a two-commodity framework, let's assume the two commodities are represented by X and Y. We can construct a diagram with the axes representing the quantities of X and Y. The indifference curves, which represent the bundles of X and Y that yield the same level of utility, can be plotted on this diagram.

Since the preference relation is continuous and monotone, we can draw the indifference curves as smooth, upward-sloping curves without any gaps or jumps. The upward slope reflects the monotonicity, indicating that more of either X or Y is preferred to less.

To represent this preference relation with a continuous utility function, we can assign utility levels to different bundles of X and Y. For example, we can assign a utility level of 1 to a specific bundle (X₁, Y₁), and higher utility levels to bundles that are preferred to (X₁, Y₁).

By assigning utility levels in a continuous manner across the diagram, we can construct a continuous utility function that represents the rational preference relation. This function will map each bundle of X and Y to a corresponding level of utility.

In conclusion, for a rational preference relation that is continuous and monotone in a two-commodity framework, there exists a continuous utility function that represents this preference relation. The utility function can be constructed by assigning utility levels to different bundles of commodities, and the resulting indifference curves on a diagram will be smooth, upward-sloping curves. This relationship between the utility function and the preference relation allows us to mathematically model and analyze the choices and preferences of individuals in economics.

Step-by-step explanation;

Split the equation into two.

x2(x-6)-9(x-6)

(x-6) is seen as one of the tiles. Now work on x2-9

x2-9 is a difference of squares meaning the last two are (x+3) and (x-3).

Answer: If the least value of n is 3, the inequality that shows all possible values of n would be: n ≥ 3

This is because "≥" means "greater than or equal to", so any value of n that is equal to or greater than 3 would satisfy the inequality.

Given :

Finley makes one batch of orange paint using 5 L of yellow paint.

To Find :

How many batches of orange paint she can make using 15 L of yellow paint.

Solution :

We need to find how many batches of orange paint she can make using 15 L of yellow paint.

Now , 1 batch requires 5 L of yellow paint .

So , 15 L of paint will make 3 batches .

Let , number of batches be N .

\(N=1 \times\dfrac{15}{5}\ batches\\\\N=3\ batches\)

Therefore, number of batches produced is 3 .

Hence, this is the required solution .

The general solution for the second differential equation is y = \(e^[(1/2)x^2 + C2] - 4\)

1. \(dy/dx = 2x/y\)

Step 1: Separate variables. To do this, multiply both sides by y and divide both sides by dx:
\(y dy = 2x dx\)

Step 2: Integrate both sides:
\(∫y dy = ∫2x dx\)

Step 3: Evaluate the integrals:
\((1/2)y^2 = x^2 + C1\), where C1 is the constant of integration.

Step 4: Solve for y to obtain the general solution:
\(y^2 = 2x^2 + 2C1\\y = ±√(2x^2 + 2C1)\)

So, the general solution for the first differential equation is \(y = ±√(2x^2 + 2C1\)).

2. \(dy/dx = x(y+4)\)

Step 1: Separate variables. To do this, divide both sides by (y+4) and multiply both sides by dx:
\(dy / (y+4) = x dx\)

Step 2: Integrate both sides:
\(∫[1 / (y+4)] dy = ∫x dx\)

Step 3: Evaluate the integrals:
\(ln|y+4| = (1/2)x^2 + C2\), where C2 is the constant of integration.

Step 4: Solve for y to obtain the general solution:
\(y+4 = e^[(1/2)x^2 + C2]\\y = e^[(1/2)x^2 + C2] - 4\)

So, the general solution for the second differential equation is y = \(e^[(1/2)x^2 + C2] - 4\)

The relation J on all positive integers is defined as follows: For all x, y in positive integers, xJy if x is a factor of y (i.e., x divides y) and the answers to the given examples are: a. False, b. True, c. True, d. False, e. True.

a. To determine if 1 J 2 is true, we need to check if 1 is a factor of 2. Since 1 does not divide 2 without leaving a remainder, 1 J 2 is false.

b. To determine if 2 J 1 is true, we need to check if 2 is a factor of 1. Since 2 does divide 1 without leaving a remainder (i.e., 2 × 0 = 1), 2 J 1 is true.

c. To determine if 3 J 6 is true, we need to check if 3 is a factor of 6. Since 3 does divide 6 without leaving a remainder (i.e., 3 × 2 = 6), 3 J 6 is true.

d. To determine if 17 J 512 is true, we need to check if 17 is a factor of 512. Since 17 does not divide 512 without leaving a remainder, 17 J 512 is false.

e. Another example of x and y in relation J could be 4 J 20, where x = 4 and y = 20. To determine if 4 J 20 is true, we need to check if 4 is a factor of 20. Since 4 does divide 20 without leaving a remainder (i.e., 4 × 5 = 20), 4 J 20 is true.

Therefore, the relation J on all positive integers is defined by whether x is a factor of y, and the answers to the given examples are: a. False, b. True, c. True, d. False, e. True.
