The number line in the image below shows the solution to the inequality 3x - 8 > 7.

How to Create a Number Line that Shows the Solution of an Inequality?

Before we can create a number line that represents the solution of an inequality, we have to solve to find the solution first.

Given the inequality 3x - 8 > 7, solve for x:

3x - 8 + 8 > 7 + 8 (addition property of equality)

3x > 15

3x/3 > 15/3 (division property of equality)

x > 5

The solution is x > 5, therefore, the image attached below shows the number line of the solution.

Liling will end up with four triangles if she starts with two tiny squares of material and cuts them on the diagonal. Knowing the areas of each of the four triangles will help us calculate the size of the larger square quilt block.

We are aware that the area of a square can be calculated by multiplying one side's length by itself (A = s2). Each of the small squares' ensuing triangles has a base and height that are equal to one-half of its side because the small squares were cut on the diagonal. Therefore, each triangle has a surface area of (1/2) x (1/2) x s2 = (1/4) x s2 = (s2)/4.

If the large quilt block is made up of four of these triangles, then the area of the quilt block is 4 x (s^2)/4 = s^2. Since the area of the large quilt block is 36 square inches, we can set up the equation:

s^2 = 36

To find the length of one side of the large quilt block (s), we can take the square root of both sides of the equation:

s = √36

s = 6 inches

So, the length of one side of the large quilt block is 6 inches, and the area of the block is 36 square inches.

The amount of trace element collected by Owen is 59.3 g.

To calculate the amount of trace element collected by Owen, we first need to find the volume of the container. Given the radius of 6.7 cm and the height of 13.3 cm, the volume of the cylinder is given by:

V = π * r^2 * h = π * (6.7)^2 * 13.3 = 615.96 cm^3

Since there are 0.097 grams of the trace element per cubic centimeter of water, the amount of trace element in the container can be calculated as:

m = V * 0.097 g/cm^3 = 615.96 cm^3 * 0.097 g/cm^3 = 59.32 g

The average velocity is 94.6km / hour

Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs. The average velocity can be positive or negative depending upon the sign of the displacement. The SI unit of average velocity is meters per second (m/s or ms-1).

therefore average velocity = change in displacement / change in time

change in displacement = 485 - 154 = 331 km

change in time = 4:30-1:00 = 3 hours 30minutes = 3½ hrs

Answer:

[tex]\displaystyle{(-1)^aa^{2a} b^a}[/tex]

Step-by-step explanation:

The following expression can be rewritten as:

[tex]\displaystyle{\left((-1)\cdot a^2 \cdot b\right)^a}[/tex]

In this case, we have to separate -1 out of a² since if a becomes even, the value of (-a)ª will become positive while (-a)ª becomes negative when a is odd.

We can apply the law of exponent when:

[tex]\displaystyle{\left(a \cdot b \cdot c \right)^m = a^m \cdot b^m \cdot c^m}[/tex]

Therefore:

[tex]\displaystyle{\left((-1)\cdot a^2 \cdot b\right)^a = (-1)^a\cdot a^{2a}\cdot b^a}\\\\\displaystyle{\left((-1)\cdot a^2 \cdot b\right)^a = (-1)^aa^{2a} b^a}[/tex]

This will make when a = even numbers, the expression is positive while negative when a is odd.

And no, the answer is not [tex]-a^{2a} b^a[/tex] since this will make the expression negative only but the problem can be positive when a = even number which is why we have to separate -1 out of -a² so that it meets the condition.

Hence, the answer is [tex]\displaystyle{(-1)^aa^{2a} b^a}[/tex]

The perimeter should be multiplied by 1/3

The side length of the square, which is 7.3 inches,

The square's surface area

Side x Side is Area = 7.3 x 7.3 = 53.29

The square's new area is multiplied by 1/9,

so area is equal to

1/9 x 53.29 and s is equal to 2.4333.

Using the length of the new square as the new perimeter, the square's new perimeter is equal to 9.733 times its side times.

Now that we have calculated the perimeter ratios, we can see that the square's side length is 7.3.

the perimeter is equal to 7.3 times 4 and equals 29.12; nevertheless,

the ratio of the perimeters of the first and second lengths is equal to

29.12/9.733 and is

And also, she buys 13 more candles every week

To find her initial number of candles purchased,

Let her initial number of purchase of candles be 'x'

According to the question,

Initial number of candles + (8 weeks * 13 candles/week) = 160 candles

Substituting x, we get

x+(13*8)=160

or, x+104=160

or, x=160-104

or, x=56

Here there is a 10% decrease in the number of streams each week after the song's release. From calculations the number of streams after sixth week is 8,503,056.

Let's look into the data given.

The initial number of streams, X₀ = 16,000,000

The percent decrease is 100- 90 = 10%

So the rate of decrease = 10/100 = 0.10

The period of time, n = 6

The equation to find the final number of streams, X =  X₀ (1-r)ⁿ

                                               = 16,000,000× (1-0.01)⁶

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given m = - 2 , then

y = - 2x + c ← is the partial equation

to find c substitute (- 4, 2 ) into the partial equation

2 = - 2(- 4) + c = 8 + c ( subtract 8 from both sides )

- 6 = c

y = - 2x - 6 ← equation of line

--------------------------------------------------------------------------

(3)

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 6 ) and (x₂, y₂ ) = (9, - 2 )

m = [tex]\frac{-2-6}{9-(-3)}[/tex] = [tex]\frac{-8}{9+3}[/tex] = [tex]\frac{-8}{12}[/tex] = - [tex]\frac{2}{3}[/tex] , then

y = - [tex]\frac{2}{3}[/tex] x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (9, - 2 )

- 2 = - [tex]\frac{2}{3}[/tex] (9) + c = - 6 + c ( add 6 to both sides )

4 = c

y = - [tex]\frac{2}{3}[/tex] x + 4 ← in slope- intercept form

3y = - 2x + 12 ( add 2x to both sides )

2x + 3y = 12 ← equation in standard form

with (x₁, y₁ ) = (0, 200) and (x₂, y₂ ) = (2, 500) ← 2 ordered pairs from the table

m = [tex]\frac{500-200}{2-0}[/tex] = [tex]\frac{300}{2}[/tex] = 150

Answer:

  (x, y) = (0.5, -3)  or  (8, 12)

Step-by-step explanation:

You want x and y such that 8, 2x, 2y is an arithmetic sequence and 2x, 2y, 36 is a geometric sequence.

The difference of successive terms is a constant for an arithmetic sequence.

  2x -8 = 2y -2x

  2x -4 = y . . . . . . . . divide by 2, add x

The ratio of successive terms is a constant for a geometric sequence.

  2y/2x = 36/2y

  y² = 18x . . . . . . . . . simplify and cross multiply

We can substitute the expression for y from the arithmetic sequence into the expression for y² in the geometric sequence:

  (2x -4)² = 18x

  4x² -16x +16 = 18x . . . . . expand

  2x² -17x +8 = 0 . . . . . . . divide by 2, subtract 9x

  (2x -1)(x -8) = 0 . . . . . . . factor

The values of x that make the factors zero are x = 1/2 and x = 8. The corresponding values of y are 2{1/2, 8} -4 = {1, 16} -4 = {-3, 12}.

The values of x and y are (1/2 and -3) or (8 and 12).

The volume of the container is 4,500 cm3.

Calculate the volume of the two cubes that make up the container.

For the cube on the left, the volume can be found by multiplying the length (15 cm) by the width (10 cm) by the height (10 cm).

15 cm × 10 cm × 10 cm = 1,500 cm3

For the cube on the right, the volume can be found by multiplying the length (20 cm) by the width (15 cm) by the height (10 cm).

20 cm × 15 cm × 10 cm = 3,000 cm3

Add the two volumes together to find the total volume of the container.
