Solve - 2x - 8> 3x + 12.Please Help!

Answers

Answer 1

Answer:

B. X < -4

Step-by-step explanation:

-2x - 8 > 3x + 12

Subtract 3x from both sides

-5x -8 > 12

Add 8 both sides

-5x > 20

Divide -5 both sides

X < -4

Answer 2

Answer: x < -4

Step-by-step explanation:

Subtract 3x from both sides

-5x - 8 > 12

Add 8 to both sides

-5x > 20

Divide both sides by -5

x < -4

Step-by-step explanation:

A point has the coordinates (0, k).

Which reflection of the point will produce an image at the same coordinates, (0, k)?

Answers

Answer:

B

Step-by-step explanation:

I took the assignmen.

The reflection of point that will produce the image at same coordinate (0, k) is across the y - axis

We have a Point with coordinates  (0, k).

We have to find the reflection that will produce the image at the same coordinate (0, k).

Consider a Point P (x, y). Find the image of the point across x - axis and y - axis.

For a Point P [tex](x,y)[/tex] the image across -

x - axis is (x, -y).y - axis is (-x, y)

We can use the above laws to find the reflection of point

For Point P(0,k) , the -

image across x - axis will be (0, -k).image across y - axis will be (-0, k), which is same as (0, k).

Hence, the reflection of point that will produce the image at same coordinate [tex](0,k)[/tex] is across the y - axis.

1. Numa escola de 670 alunos, 352 estudam Inglês, 125 fazem apenas o curso de Espanhol e 85 estudam as duas línguas. Com base nessas informações, determine: a) Quantos estudam Inglês ou Espanhol? b) Quantos fazem espanhol? c) Quantos não estudam nenhuma dessas línguas?

Answers

Answer:

a) Quantos estudam Inglês ou Espanhol?

477

b) Quantos fazem espanhol?

210

c) Quantos não estudam nenhuma dessas línguas?

193

Step-by-step explanation:

a) Quantos estudam Inglês ou Espanhol?

Inglês ou Espanhol = Quantidade de alunos que cursam inglês + Quantidade de alunos que cursam espanhol - Quantidade de alunos que cursam inglês e espanhol

= 352 + 210 - 85

= 477

b) Quantos fazem espanhol?

Isso é dado na pergunta como alunos que só aprendem espanhol = Somos informados de que o número de alunos que estudam apenas espanhol = 125

Número de alunos que cursam espanhol = Número de alunos que cursam apenas espanhol + Número de alunos que cursam espanhol e inglês

Número de alunos que fazem espanhol = 125 + 85

= 210 alunos

c) Quantos não estudam nenhuma dessas línguas?

Número total de alunos - (número de alunos que não cursam nenhum dos idiomas) = ​​Número de alunos que cursam inglês + Número de alunos que cursam espanhol - Número de alunos que cursam os dois

= 670 - (número de alunos que não estudam nenhum dos idiomas) = ​​352 + 210 - 85

= 670 - (número de alunos que não estudam nenhum dos idiomas) = ​​477

Número de alunos que não cursam nenhum dos idiomas = 670 - 477

= 193 alunos

Mr.V's trail mix uses 1/2cup of peanuts, 2 1/4 cups raisins, and he uses 2 times more sunflower seeds than raisins.How many total cups of trail mix can mix can Mr.V make

Answers

Answer:

The total number of cups is 9 1/2 cups

Step-by-step explanation:

Here, we are interested in calculating the total cups of trail mix that Mr V can make.

From the question, we are told that he used 1/2 cups of peanuts, 2 1/4 cups of raisins and 2 times more sunflower seeds than raisins.

So basically, we need to find the number of cups of sunflower seeds used.

The information we have here is that he used 2 times more of raisins;

Thus, the number of cups of sunflower would be 2 * 2 1/4 = 2 * 9/4 = 9/2. But practically is 9/2 , two times more than 2 1/4? NO!

What we should do here is to add 9/2 to 2 1/4. In that case, the difference between the two will be 2 times the cups of raisins;

So 9/2 + 9/4 = (18 + 9)/4 = 27/4

So the total number of cups of trail mix that can be made will be;

1/2 + 27/4 + 9/4 = (2 + 27 + 9)/4 = 38/4 = 19/2 = 9 1/2 cups

2|3x - 2|= 14 how would you solve this absolute value equation?

Answers

Answer: 2. |3x-2|= 14

|3x-2|=2.7/2

|3x-2|=7

x∈ {3,-5/3

Step-by-step explanation: \frac{5}{3}

Answer:

x = 3x = - 5/3

Step-by-step explanation:

2|3x - 2|= 14|3x - 2|= 7

1) 3x - 2 ≥ 0 ⇒ 3x ≥ 2 ⇒ x ≥ 2/3

3x - 2 = 73x = 9x = 3  is valid root as 3 ≥ 2/3

2) 3x - 2 < 0 ⇒ 3x < 2 ⇒ x < 2/3

- (3x - 2) = 73x - 2 = -73x = -5x = -5/3  is valid root as -5/3 < 2/3

7) A real number that is less than zero. These represent opposites.

Answers

Answer:

A negative number

Step-by-step explanation:

I know this is right. Negative numbers represent opposites. If positive represents a movement to the right, negative represents a movement to the left.In the context of negative numbers, a number that is greater than zero is referred to as positive. Thus every real number other than zero is either positive or negative, while zero itself is not considered to have a sign. Positive numbers are sometimes written with a plus sign in front, e.g. +3 denotes a positive three.

It’s a negative number because anything less then Zero is negative

Step-by-step explanation:

Scientific notation is a representation of a large number in a short form. The answer, 1*10^12 (read as ten to the twelfth power) essentially says that the number when expanded is 1 with 12 zeros appended to it. If you did a number like 7 trillion you would have 7 * 10^12.

Same thing can be applied for 1,000,000 (one million).

1 * 10^6 because one million has 6 zeros appended to it.

2) The wire length 176 cm is first bent into a square
and then into a circle
which one will have more area? (II= 22/7)

Answers

Length of Wire = 176 cm

It's bent into a square.

Side of square = 176/4 = 44 cm

Area of square = Side × Side = 44 × 44 = 1,936 sq.cm

Then it's bent into a circle.

Circumference of the circle = 2πr = 176 cm

Circumference = r = 176/2 × 7/22 = 28 cm

Area of circle = πr^2

Area = 22/7 × 28 × 28

Area = 2,464 sq.cm

The Circle will have more area than the square.
