The compound inequality for the graph is -5 ≤ x ≤ -1

On the graph, we have the following endpoints

Also, the region between endpoints is shaded.

This means that the endpoint is a union inequality

So, we have the compound inequality to be

Endpoint 1 ≤ x ≤ Endpoint 2

This gives

-5 ≤ x ≤ -1

Hence, the compound inequality for the graph is -5 ≤ x ≤ -1

Answer:

x = 1/2 and

x = -15/2

Step-by-step explanation:

First, get the absolute value alone on one side if the equation.

2 |2x + 7 | = 16

Divide both sides by 2.

| 2x + 7 | = 8

Once the absolute value sign is by itself, you will separate the equation into two separate equations.

2x+7=8 and 2x+7=-8

Solve these two equations separately and get two solutions.

2x + 7 = 8

Subtract 7.

2x = 1

Divide by 2.

x = 1/2 Here is one solution.

2x + 7 = -8

Subtract 7.

2x = -15

Divide by 2.

x = -15/2 Here is a second solution.

Answer:

x = - [tex]\frac{15}{2}[/tex] , x = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

2 | 2x + 7 | = 16 ( divide both sides by 2 )

| 2x + 7 | = 8

the absolute value function always gives a positive result, but the expression inside can be positive or negative , that is

2x + 7 = 8 ( subtract 7 from both sides )

2x = 1 ( divide both sides by 2 )

x = [tex]\frac{1}{2}[/tex]

or

- (2x + 7) = 8

- 2x - 7 = 8 ( add 7 to both sides )

- 2x = 15 ( divide both sides by - 2 )

x = - [tex]\frac{15}{2}[/tex]

As a check

substitute these values into the left side and if equal to the right side then they are a solution

x = [tex]\frac{1}{2}[/tex]

2 | 2([tex]\frac{1}{2}[/tex] ) + 7 | = 2 | 1 + 7 | = 2 | 8 | = 16 = right side

x = - [tex]\frac{15}{2}[/tex]

2 | 2(- [tex]\frac{15}{2}[/tex] ) + 7 | = 2 | - 15 + 7 | = 2 | - 8 | = 2 | 8 | = 16 = right side

then x = - [tex]\frac{15}{2}[/tex] and x = [tex]\frac{1}{2}[/tex] are the solutions

The orange will fall 64 feet in 8 seconds.

Distance:

Distance is defined as how much ground an object has covered despite its starting or ending point.

Given,

The distance a falling object travels towards the earth is directly proportional to the square of the time that it falls.

And an orange falls 16 feet in 4 seconds.

Here we need to find the how far it will fall in 8 seconds.

Based on the given details,

We know the that distance is,

D = kt²  

where

k is the constant of proportionality.  

To find the value of k we have to apply the given values on the equation.

=> 16 = k x (4)²

=> 16 = k x 16

=> k = 16/16

=> k = 1.

So, in 8 seconds it will fall at

=> D = 1 x (8)²

=> D = 1 x 64

=> D = 64 feet.

Therefore, the orange will fall at 64 feet in 8 seconds.

The volleyball team ended up practicing for 1.2 hours on Friday.

The total number of hours the volleyball team practiced on Monday, Tuesday, Wednesday, and Thursday can be determined by adding the values given in the statement.

Therefore,

the total number of hours the team practiced on Monday, Tuesday, Wednesday, and Thursday=0.5 hours+1.3hours+2.2hours+0.8hours= 4.8 hours

Total number of hours the team practiced last week = 6 hours

The number of hours they practiced on Friday can be calculated by subtraction of the total number of hours of the week from the total number of hours on Monday, Tuesday, Wednesday, and Thursday.

Hence, the number of hours the team practiced on Friday = 6 - 4.8= 1.2 hours.

No, the Adoncia drawing will not fit on the drawing sheet.

Given adoncia is drawing to scale, she uses a 15-foot scale in the 1-inch monument. And in the drawing, the front of the monument is about 80 feet high and 200 feet long.

The given parameters are;

The scale of the drawing in the front of the monument is 15 ft = 1 in.

Actual size of the monument;

Height = 80 feet

Length = 200 feet.

So we have;

Required size of  paper height = 80/15 = 16/3 = 5.33 in.

Required size of  paper length = 200/15 = 40/3 = 13.33 in.

The size of the paper is 11 in. about the size of a standard 8.5-inch sheet of letterhead. equals 11 in.

Design length, 13.33" > Paper length > 11".

The dimensions of the original photo are 6 x 6.

A rectangle is a quadrilateral having four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.

The formula for a square's area, A = s², is the side length raised to the power of two. The 256 in2 section of the larger image was made available to us. Additionally, it was mentioned that the length of the expanded image is equal to the original image's length plus ten inches.

We can therefore create an equation to solve for x, which stands for the length of the original snapshot, based on the aforementioned statements.

The right answer is that there are four electrons.

The charge number of an atomic nucleus is the chemical element's atomic number, also known as the nuclear charge number.

For conventional nuclei, this is comparable to the proton number, or the number of protons found in the nucleus of each atom of that element.

Equal numbers of protons and electrons make up a neutral atom. This figure establishes the atom's atomic number.

The fourth element on the periodic table is beryllium.

Number of protons in Be-atom = 4

Number of electrons in Be-atom = 4

Here we need to use the general relation:

Distance = Speed*Time.

Here we know that Alisa's speed is 55 miles per hour, and she drives for 1.8 hours, then we can replace:

Speed = 55 mi/h

Time = 1.8 hours

Rita, John, and Kareem sent  17, 7, and 68 messages, respectively.

Use algebraic expressions to solve this problem.

Let x, y, and z be the number of messages sent by Rita, John, and Kareem, respectively.

If Rita, John, and Kareem sent a total of 92 text messages during the weekend, then:

x + y + z = 92

If Kareem sent 4 times as many messages as Rita, then:

z = 4 * x

z = 4x

If John sent 10 fewer messages than Rita, then:

y = x - 10

Evaluating z = 4x and y = x - 10 to the first equation:

x + y + z = 92

x + (x - 10) + 4x = 92

x + x - 10 + 4x = 92

6x = 92 + 10

6x = 102

x = 17

Recall that y = x - 10:

y = 17 - 10

Option B) is correct that is shape 2 is congruent to shape 1 because shape 2 is reflection of shape 1.

We know that two figures or objects are congruent if they have the same shape and size or they are the mirror image of each other.

Translation : It simply means moving. Every point should be moved in same distance and in same direction

Rotation : It means turning around a center.

Reflection : In this, the image is of the same size as the pre-image.

So according to the given figure we can see that the shape is not translated or rotated from a center but is reflected as shape 1 is the image of shape 2.
