Absolute value equation for a straight horizontal line with marked points and x-axis intercepts. Therefore, the absolute value equation that has the given solution set is:y + 1 = | x + 3 | .

How to write an absolute value equation that has the following solution set?

To find the absolute value equation that corresponds to the given solution set, we need to determine the axis of symmetry of the V-shaped graph formed by the absolute value function. The axis of symmetry is the vertical line that passes through the vertex of the graph. Since the vertex of the graph is located at the midpoint of the two given points, which is at x = -3, the axis of symmetry is x = -3.

The equation of the absolute value function can be written as:

b + | x - a |  

= y

where a is the x-coordinate of the vertex and b is the y-coordinate of the point where the graph intersects the y-axis. In this case, the y-coordinate of the point where the graph intersects the y-axis is -1, so we have b = -1.

Substituting the value of a and b in the equation above, we get:

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

Simplifying the equation, we get:

y + 1  = | x + 3 |

Therefore, the absolute value equation that has the given solution set is:

y + 1 = | x + 3 | .

Answer:

(56 3/4 + 1 3/8) + 1 1/5 = 58 + 23/5 = 293/5 or 58.6

Step-by-step explanation:

The sum of (56 3/4 + 1 3/8) + 1 1/5 can be calculated as follows:

First, we need to add the whole numbers:

56 + 1 + 1 = 58

Next, we add the fractions:

3/4 + 3/8 = (6/8) + (3/8) = 9/8

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 1:

9/8 ÷ 1/8 = 9

Finally, we add the last fraction:

9 + 1/5 = (45/5) + (1/5) = 46/5

Again, we can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 2:

46/5 ÷ 2/2 = 23/5

Therefore , the solution of the given problem of fraction comes out to be 1600 grams of 30% sulfuric acid were created using 1200 grams of 20% sulfuric acid and 400 grams of 60% sulfuric acid.

Any arrangement of components of the same size can be used to depict the whole. Quantity is referred to as "a portion" in a specific measure in Standard English. 8, 3/4. Fractions are included in wholes. In mathematics, numbers are represented by the ratio, and these is the ratio's divisor. These are all examples of basic fractions that might be divided by whole integers. The remainder is a difficult fraction despite the amount itself includes a fraction.

Here,

Assume that 1600 grams of a combination of 30% sulfuric acid and 60% sulfuric acid were created using x grams of 20% sulfuric acid and y grams of 60% sulfuric acid.

Equation 1: 1600 = x plus y (total amount of solution)

Equation 2: 0.3(1600) = 0.2x + 0.6y (total amount of solute)

By condensing Equation 2, we obtain:

=>  0.2x + 0.6y = 480

=>  2x + 6y = 4800

=>  x + 3y = 2400

Formula 3:

=>  x + y = 1600

=>  x + 3y = 2400

=>  2y = 800

=>  y = 400

=>  x + 400 = 1600

=> x = 1200

Answer: To write the proportional relationship between books and months, we can use the formula:

unit rate = (total books) / (total months)

Let's calculate the total books and months for Estelle's reservations:

Two years ago: 24 books in 4 months

Last year: unknown number of books in 36 months

This year: 18 books in 3 months

To find the total number of books for last year, we can use a proportion:

24 books / 4 months = x books / 36 months

Cross-multiplying, we get:

24 * 36 = 4 * x

x = 24 * 9

x = 216

So Estelle reserved 216 books in 36 months last year.

Now we can calculate the unit rate:

unit rate = (total books) / (total months)

unit rate = (24 + 216 + 18) / (4 + 36 + 3)

unit rate = 258 / 43

unit rate = 6

Therefore, the proportional relationship between books and months is:

books = 6 * months

Step-by-step explanation:

Step-by-step explanation:

The area of each part of the figure and the whole figure is Rectangle A = 15 square units
Triangle B = 6 square units
Rectangle C = 8 square units
Whole figure = 29 square units

To find the area of each part of the figure, we need to use the formula for the area of a rectangle and the area of a triangle.

Let's start with Rectangle A. We can see from the figure that its length is 5 units and its width is 3 units. To find its area, we use the formula A = l x w, where A represents the area, l represents the length, and w represents the width. So, for Rectangle A, we have:

A = 5 x 3 = 15 square units

Next, let's move on to Triangle B. We can see from the figure that the base of the triangle is 4 units and the height is 3 units. To find its area, we use the formula A = (1/2) x b x h, where A represents the area, b represents the base, and h represents the height. So, for Triangle B, we have:

A = (1/2) x 4 x 3 = 6 square units

Finally, let's find the area of Rectangle C. We can see from the figure that its length is 4 units and its width is 2 units. To find its area, we use the same formula as for Rectangle A:

A = 4 x 2 = 8 square units

Now that we have the area of each part, we can add them up to find the whole figure. So, we have:

Whole figure = Rectangle A + Triangle B + Rectangle C
Whole figure = 15 + 6 + 8
Whole figure = 29 square units

Therefore, The area of each part of the figure and the whole figure are as follows:
Rectangle A = 15 square units
Triangle B = 6 square units
Rectangle C = 8 square units
Whole figure = 29 square units

The probability of not seeing the ad given that the person purchased the game is 0.388.

Probability is a number between 0 and 1, where 0 represents impossibility and 1 represents certainty.

Let A be the event that a person has seen the advertisement, and B be the event that a person has purchased the game. We want to find the probability of not seeing the ad given that the person purchased the game, i.e. P(A' | B).

From the problem, we know that:

P(A) = 0.24 (24% of the market has seen the ad)

P(B | A) = 0.42 (42% of those who see the ad have purchased the game)

P(B | A') = 0.07 (93% of those who have not seen the ad have not purchased the game)

We can use the law of total probability to find P(B), the probability of purchasing the game:

P(B) = P(B | A) * P(A) + P(B | A') * P(A')

       = 0.42 * 0.24 + 0.07 * 0.76

       = 0.1296 + 0.0532

       = 0.1828

Now, we can use Bayes' theorem:

P(A' | B) = P(B | A') * P(A') / P(B)

Substituting the values we have:

P(A' | B) = 0.93 * 0.76 / 0.1828

             = 0.388

The answer of the given question based on circle  is ,  the width of the shaded region is 4 inches, and the answer is (a).

Radius is distance from center of  circle to any point on circle. It is a fixed length and is the same for all points on the circle. The radius is usually denoted by the letter "r".

The radius is an important parameter of a circle and is used in many geometric calculations, like finding the circumference, area, diameter, chord length, and arc length of a circle. The diameter of a circle is twice the radius, and the circumference of a circle is equal to 2π times the radius.

The area of shaded region is equal to area of the outer circle minus area of inner circle. We are given that the area of the shaded region is 56π in², and the radius of the inner circle is 5 in.

Let radius of outer circle be " r ". Then we have:

Area of the shaded region = Area of the outer circle - Area of the inner circle

56π = πr² - π(5²)

56π = π(r² - 25)

r² - 25 = 56

r² = 81

r = 9

So, the radius of the outer circle is 9 inches.

The width of the shaded region is the difference between the radius of the outer circle and the radius of the inner circle:

Width of shaded region = 9 in - 5 in = 4 in

Therefore, the width of the shaded region is 4 inches, and the answer is (a).
