What x value makes this equation true -12x - 2(x+9) = 5(x+4)

A. -2
B. 13/19
C. 5
D. -1/3

Answers

Answer 1

Answer:

A. -2, x= -2

Step-by-step explanation:

Answer 2

Answer:

A

Step-by-step explanation:

Given

- 12x - 2(x + 9) = 5(x + 4) ← distribute parenthesis on both sides )

- 12x - 2x - 18 = 5x + 20 , that is

- 14x - 18 = 5x + 20 ( subtract 5x from both sides )

- 19x - 18 = 20 ( add 18 to both sides )

- 19x = 38 ( divide both sides by - 19 )

x = - 2 → A

Answers

Answer:

Step-by-step explanation:

y=3x-14

standard  form : 3x-y=14 ( move variable together on one side )

convert y-6=-1/3 (x-9) to standard form :

first : y-6 = -1/3 x -1/3(-9)

y-6=-1/3 x +9/3

y-6=-1/3x+3

y+1/3x =3+6

y+1/3x=9 ( common denominator)

(3y+x)/3=9 ( cross multiplication)

3y+x=3(9)

3y+x=27

Convert 3x+y=9 (standard form) to slope intercept form (y=mx+b)

3x+y=9

y=-3x+9

Becky leaves school to go home. She walks 6 blocks North and then 8
blocks west. How far is Becky from the school?

Answers

Answer:

10 blocks

Step-by-step explanation:

The distance of Becky from the school is 10 blocks.

What is Pythagoras's theorem?

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

We have been given that Becky leaves school to go home. She walks 6 blocks North and then 8 blocks west.

According to the given situation, we can plot the diagram which has been attached below.

As per the figure, we have a right triangle that has :

AB = 8 blocks, and BC = 6 blocks

The distance of Becky from the school is equal to the length of AC.

By Pythagoras's theorem,

AC² = AB² + BC²

AC² = 8² + 6²

AC² = 64 + 36

AC² = 100

AC = 10 blocks

Therefore, the distance of Becky from the school is 10 blocks.

-10y = -90

y = 9 and x = 94 9%2A9%2B13

and...checking

sum = 103

Step-by-step explanation:

The two numbers are 9 and 94.

What are simultaneous equations?

In mathematics, a set of simultaneous equation, also known as a system of equations or an equation system, is a set of equations for which common solutions are sought.

Let the two numbers be x and y.

Then according to question,One number is 13 more than the product of 9 and another number we have ,

13 + 9x = y  

or,9x - y = -13...(i)

Also,the sum of the two numbers is 103. So we have,

x + y = 103 ...(ii)

Adding equation (i) and (ii) we get,

10x = 90

or, x = 9

Put the value of x in equation (ii), we get

9 + y = 103

or, y = 103 - 9

or, y = 94

Hence the two numbers are 9 and 94.

Find the distance between the two points. (round to the nearest hundredths)



distance:

Answers

Answer:

d = 5.10

Step-by-step explanation:

The distance between two points is given by

d = sqrt( ( y2-y1)^2 + ( x2-x1)^2 )  where ( x1,y1) and ( x2,y2) are the two points

d = sqrt( ( 5-6)^2 + (8-3)^2 )  

d = sqrt( ( -1)^2 + (5)^2 )  

d = sqrt(  1+25)

d = sqrt(26)

d = 5.099019514

Rounding to the nearest hundredth

d = 5.10

Answer:

[tex]d=\sqrt{26}\approx5.10[/tex]

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

We can see that Point R is at (3,6), and Point E is at (8,5).

Let's let (3,6) be (x₁, y₁) and let's let (8,5) be (x₂, y₂). So, substituting them into our formula, we'll get:

[tex]d=\sqrt{(8-3)^2+(5-6)^2[/tex]

Subtract:

[tex]d=\sqrt{(5)^2+(-1)^2[/tex]

Square:

[tex]d=\sqrt{25+1}[/tex]

Add:

[tex]d=\sqrt{26}[/tex]

Approximate. Use a calculator:

[tex]d=\sqrt{26}\approx5.10[/tex]

So, the distance between RE is approximately 5.1 units.

And we're done!

The sum of five consecutive integers is five. What is the product of the five integers?

Answers

The first integer = x

The second integer = x + 1

The third integer = x + 2

The fourth integer = x + 3

The fifth integer = x + 4

Since they all add up to 5, let's set them equal to 5

x + x + 1 + x + 2 + x + 3 + x + 4 = 5

Combine like terms

5x + 10 = 5

Subtract 10 from both sides

5x = -5

Divide each side by 5

x = -1

The first integer = x = -1

The second integer = x + 1 = -1 + 1 = 0

The third integer = x + 2 = -1 + 2 = 1

The fourth integer = x + 3 = -1 + 3 = 2

The fifth integer = x + 4 = -1 + 4 = 3

We can check this by adding all the integers together and making sure we get 5

3 + 2 + 1 + 0 - 1 = 5

Answer:

0

Step-by-step explanation:

If the sum of the integers is 5, then the arithmetic mean of the integers is [tex]$\frac{5}{5}=1$[/tex] .  In five consecutive integers, the arithmetic mean is equal to the middle integer, which means the integers are -1, 0, 1, 2, 3 and the product is [tex]$\boxed{0}$[/tex].

Se sabe que los catetos de un triangulo rectangulo miden 0,4 cm y 0,3 cm. Micaela dice que su perimetro es igual a 1,2 cm ¿Sera cierto? De no ser asi , determina el valor del perimetro correcto

Answers

Answer:

El perímetro es de 1.2 cm

Step-by-step explanation:

La formula del perímetro de un triángulo rectángulo es:

p = cateto1 + cateto2 + hipotenusa

Para determinar el valor de la hipotenusa usamos el Teorema de Pitágoras:

hipotenusa² = cateto1² + cateto2²

hipotenusa² = 0.4² + 0.3²

hipotenusa² = 0.16 + 0.09

hipotenusa² = 0.25

√hipotenusa² = √0.25

hipotenusa = 0.5

entonces, el perímetro es:

p = 0.4 + 0.3 + 0.5

p = 1.2cm

por tanto

Micaela tiene razón, el perímetro es de:

1.2 cm
