What is the best approximation of the solution to the system to the nearest integer values? ( 1 , -6 ) ( 2 , 7) ( -6 , 1 ) ( 0 , -7 )

Answer:

A,C,E,F

Step-by-step explanation:

when it is 0=0 it means it is true for all.  or x=x.

The true statements for x are letters: A,C, E, and F.

Here it is important to remember the rules for the  addition of integers numbers:

+  +   Add  Final result (+)  - Final result (+)  

-   -   Add  Final result (-)  - Final result (-)  

+  -   Subtract - Final result (the sign of the integer having a greater value)

-   +  Subtract - Final result (the sign of the integer having a greater value)

The rules for multiplication of numbers are:

The result presents a positive sign (+) because the signs are the same.

The result presents a negative sign (-) because the signs are different.

For solving this question, you should apply the rules presented previously. And after that check, if your result is the same that the question gives.

7x + (2x + 7) = 9x + 7

7x+2x+7

9x+7=9x+7

True

7x + (2x - 1) = 9x + 1

7x+2x-1

9x-1≠9x + 1

False

3x + (10 - 3x) = 10

3x+10-3x

10=10

True

5x – (8 - 6x) = -x - 8

5x-8+6x

11x-8≠-x - 8

False

4x - (2x + 8) = 2x - 8

4x-2x-8

2x-8=2x-8

True

6x - (2x - 4) = 4x + 4

6x-2x+4

4x+4=4x+4

True

Answer:

5x -2

Step-by-step explanation:

literally did this in my head but

2 * x = 2x

2 * -1 = -2

2x + 3x = 5x -2

Answer:

5x-2

Step-by-step explanation:

3x+2(x-1)

Answer:

The top door is .25 feet taller than the bottom one.

Step-by-step explanation:

8. Conduction.  (Conduction is the transfer of heat that happens when particles  collide with each other. It can happen in solids, liquids, and gases.)

Before the pan is placed on the burner, its particles are moving at  the same average speed. The whole pan is at the same  temperature. The hot burner is at a much higher temperature. In  other words, the particles that make up the burner are moving at a greater average speed and  therefore have greater thermal energy.

8b. Convection.  During convection, however, the particles themselves move. This  happens only in liquids and gases because the particles in solids are stuck in place and cannot  move.

Answer:

8. Conduction happens it transfers the heat when particles collide with each other. Before the pan is placed on the burner, its particles are moving at the same average speed. The whole pan is at the same  temperature. The hot burner is at a much higher temperature, than the pan which causes the particles to move at a uneven speed.

8 b. Convection.  During convection, the particles move. This happens only to liquids and gases particles because in solid objects the particles get stuck which doesn’t allow them to move around.

[tex]x = \frac{72}{12} [/tex]

[tex]x = 6[/tex]

Answer:

x=2

Step-by-step explanation

The First step is to distribute the '2" into the parenthesis.

thus, you have 8x + 8 = 24

now we need to get x by itself so we will subtract 8 from both sides to get 8x by itself.

we know have 8x = 16

now divide by 8 to get x

x=2

Answer:

2/5% 1/8 1.125

Step-by-step explanation:

prove me wrong

Answer:

2/5%, 1/8, 1.125

Step-by-step explanation:

1/8 in a decimal would be 0.125

2/5% in a decimal would be 0.004

Pattern x. Starting number: 8, add 4.

Add 4 each time to the number, to get the answers:

8 + 4 = 12

12 + 4 = 16

Order:

x: 8 , 12 , 16

Pattern y. Starting number: 4, add 2.

Add 2 each time to the number, to get the answers:

4 + 2 = 6

6 + 2 = 8

Order:

y: 4 , 6, 8

Answer:

Answer:

17x + 4

Step-by-step explanation:

The -(- would be turned into a positive due to the rule of two negatives makes a positive. You wouldn't add the 4 into either of the numbers with a variable, you would only add the 10x and 7x.

Answer:

3x+4

Step-by-step explanation:

Apply the distributive property to get 10x - -4-(7x). Now we can turn the two negatives into a positive to get 10x+4-7x. Now, subtract 7x from 10x to get 3x. This will leave you with 3x+4.

Answer:

Just read explanation

Step-by-step explanation:

In Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. It can also be defined as an equiangular quadrilateral, since equiangular means that all of its angles are equal. It can also be defined as a parallelogram containing a right angle. A rectangle with four sides of equal length is a square. The term oblong is occasionally used to refer to a non-square rectangle. A rectangle with vertices ABCD would be denoted as ABCD.

To figure out the area of a parallelogram, we need to identify its formula. However, I do know the formula, which is Area = Base x Height.

Area = Base x Height

Area = 8 x 12

        = 96 cm squared

Therefore, the answer it 96 cm squared. By the way, I recommend that you review and comprehend the topic regarding area. Try memorizing all formulas for the shapes.

Rectangle & Square: Area = length x width

Triangle: Area = base x height

                                    2

Trapezoid: Area = (Base 1 + Base 2) x h

                                             2

Pararellogram: Area = base x height

Circle: Area = pi x r sqaured

Those are all the formulas I can recall; however, there might be more.
