Graph the line with the slope 1/3 and x-intercept 3

The solution of the equations: 2x+3y=3, 3x+2y=7​ is x =0  and y =1.

Equation:

An equation is a mathematical formula containing two algebraic expressions on either side of an equal sign (=). It shows the equivalence relation between the formula written on the left and the formula written on the right. In any formula, L.H.S = R.H.S (left side = right side). We can solve equations to find the values ​​of unknown variables that represent unknown quantities. If a statement doesn't have an equals sign, it means it's not an equation. considered to be an expression.

According to the question:

Given in the question:

2x+3y=3                         --------------------------------------- (1)

3x+2y=7                         ---------------------------------------- (2)

Multiplying Equation (1) by 3 and (2) by 2, we get:

6x + 9y = 9                                 --------------------------------- (3)

6x + 4y = 14                                --------------------------------- (4)

Now,

Subtracting equation (4) from (3)

5y = 5

⇒ y = 1

Now, putting y = 1 in equation (1) we get:

   2x + 3 × 1 = 3

⇒ 2x + 3 = 3

⇒ x = 0

Therefore, x =0 and y=1.

Marhall made 9 ales this week, earning a base of $186 plus $15 per ale. Vickie earned a base of $48 plus $18 per ale. Since both of them earned the same amount, we can set up the equations

Marhall made 9 ales this week.

Step by explanation

We can use an equation to solve this problem.

Let x = number of ales Marhall made

Marhall's Earnings = 186 + (15 x)

Vickie's Earnings = 48 + (18 x)

Since both of them earned the same amount, we can set up the equations and solve for x:

186 + (15 x) = 48 + (18 x)

15x = 138

x = 9

Therefore, Marhall made 9 ales this week.

Marhall made 9 ales this week, earning a base of $186 plus $15 per ale. Vickie earned a base of $48 plus $18 per ale.

The arithmetic sequence function is c)f(n)=25 + 6(n-1).

What is arithmetic sequence?

An arithmetic sequence is one in which each phrase grows by adding or removing a certain constant, k. In a geometric sequence, each term rises by dividing by or multiplying by a certain constant k.

Here the given series 25,31,37,43,...

First term [tex]a_1[/tex]= 25

Now Common difference d = [tex]a_2-a_1[/tex]=31-25 = 6.

Now using arithmetic sequence formula,

[tex]f(n)=a_1+(n-1)d[/tex]

Here putting indicated value  [tex]a_1[/tex]= 25 and d=6

=> f(n) = 25 + (n-1)6

=> f(n) = 25 + 6 (n-1)

Hence the correct option is c)f(n)=25 + 6(n-1).

The value of exponential 4 is 4^4, or 256. it means that 4 should be multiplied by itself 4 times.

In mathematics, an exponential is a number that is multiplied by itself a certain number of times. For example, when 4 is used as an exponential, it means that 4 should be multiplied by itself 4 times. This is written as 4^4, or 4 to the fourth power. This means that 4 is multiplied by itself 4 times, resulting in the value of 256.

Exponentials can be used to calculate the power of a number. For example, in the case of 4^4, 4 is the base number and 4 is the exponent. An exponent is the number of times a base number is multiplied by itself. In this case, the base number (4) is being multiplied by itself 4 times, resulting in a value of 256.

In addition, exponentials can be used to solve equations. For example, if we need to solve for x in the equation 4^x = 256, we can use the exponential 4 to determine the value of x. In this case, x = 4 because 4^4 = 256.

The total cost of a pair of sandals is given by the equation A = $ 18.39

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of pair of sandals be represented as A

Now , the equation will be

The total amount spent by Bonnie = $ 77.77

The cost of one shirt = $ 11.49

So , the cost of 2 shirts = 2 x 11.49 = $ 22.98

And , the cost of 1 pair = $ 32

The total tax on the purchase = $ 4.40

So , the cost of pair of sandals A = total amount spent by Bonnie - cost of 2 shirts - cost of 1 pair - total tax on the purchase

Substituting the values in the equation , we get

The cost of pair of sandals A = 77.77 - 22.98 - 32 - 4.40

Negative of an image can be obtained by subtracting each pixel values from 1.

Pixel value is the numerical representation of a color in an image. It is the amount of brightness or darkness of a pixel in an image, usually ranging from 0 (black) to 255 (white). Pixel values are used to determine how an image should be displayed on a monitor or printed on a page.It is usually measure of brightness of pixel with the higher number indicating brighter pixel and lower number indicating darker pixel.

This can be done by subtracting the pixel values r and s from 1, so the new value of each pixel would be 1-r and 1-s. This process of subtracting each pixel value from 1 is known as “inverting”.

The correct equation for this given situation is,

⇒ d = 9.5t + 11

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

John is driving around town. When he reaches the gas station, he notes that he has traveled 11 miles.

And, He reaches home 2 hours later and notes that he has traveled 30 miles.

Now, Let d represents the distance and t represents the time, in hours

So we get;

Let the equation which model this situation,

⇒ d = a t + b

Where a and b are constant.

Let the gas station is the starting point.

So, at gas station t = 0 , d = 11

Hence,

⇒ 11 = 0 × a + b

⇒ b = 11

When he reaches home 2 hours later notes that he has traveled 30 miles.

And, with substituting with b = 20

⇒ 30 = 2 × a + 11

⇒2a = 30 - 11 = 19

⇒ a = 19/2 = 9.5

So, We get the equation,

⇒ d = 9.5t + 11

On adding the integers we get:

The collection of whole numbers and negative numbers is known as an integer in mathematics. Integers, like whole numbers, do not include the fractional portion. Integers can therefore be defined as numbers that can be positive, negative, or zero but not as fractions.

For, (-78) + (98)

Step 1: Locate the first number, which is -78.

Step 2: Locate the second number, which is 98.

Step 3: Add the two numbers together by starting with the first number and counting up or down according to the sign of the second number. In this case, 98 is positive, so we count up 98 from -78.

Step 4: The answer is 20

d. The probability that a random sample of 50 cans produces a sample mean amount of 11.9 ounces or less is 0.0386.

We do not know the shape of the distribution, so we cannot calculate the probability that a single randomly selected can contains 11.9 ounces or less. The question given have not told us that the distribution of individual cans was normal, and we cannot assume it is so; therefore, we cannot calculate its probability.

As given information the mean μx = 12.

And standard deviation σx = σ / √n = 0.4 / √50 = 0.566.

The shape of the distribution described in part b is symmetrical, because the two sides of the distribution are a mirror image of each other. Therefore, it is normal distribution.

Since the sample is large n = 50 and 50 > 30, so by CLT (Central Limit Theorem), the distribution of sample means is approximately normal N(12, 0.0566). So, P(x ≤ 11.9) = normalcdf (0, 11.9, 12, 0.0566) = 0.0386.
