Answer:

15/2 or 7.5

Step-by-step explanation:

-4(x-1)+6x=2(17-x) PEDMAS

-4x+4+6x=34-2x combine terms

2x+4=34-2x subtract 4 and add 2x

4x=30  divide by 4

x=15/2

Answer:

Step-by-step explanation:

-4x + 4 + 6x = 34 - 2x

Solving like terms

2x + 4 = 34 - 2x

Bringing like terms on one side

2x + 2x = 34 - 4

4x = 30

x = 30/4

x = 15/2

ANSWER

GIVEN:

OA= 3x-1 , OC= 5x-3, OD= 6x-5 , BO = 2x+1

AO/OC = BO/OD

[The diagonals of a Trapezium divide each other proportionally]

(3x-1)/(5x-3) =( 2x+1)/(6x-5)

(3x-1) (6x-5) = (5x-3) ( 2x+1)

3x(6x-5) -1 (6x-5) = 2x(5x-3)+1(5x-3)

18x² -15x -6x +5 = 10x² -6x +5x -3

18x² -21x +5 = 10x² - x -3

18x² -10x² -21x + x +5+3 =0

8x² - 20x +8= 0

4(2x² -5x +2) = 0

2x² -5x +2 = 0

2x² -4x -x +2= 0

[By factorization]

2x(x-2) -1(x-2)= 0

(2x-1) (x-2) = 0

(2x-1) = 0 or (x-2) = 0

x = ½ or x = 2

If we put x= ½ in OD , The value of OD is negative.

Hence, the value of is x = 2.

What you do is you plug the y equation on top and you substitute it in for the y on the equation below. You have -3x=-2(-5x+8)-10

Answer:

m∠ULE = 60°

Step-by-step explanation:

To find the measure of ∠ULE we will use the property of exterior angle of a triangle.

Since, measure of an exterior angle of a triangle is equal to the sum of two opposite interior angles.

m∠LUR = m∠LEU + m∠ULE

109° = 49° + m∠ULE

m∠ULE = 109 - 49

             = 60°

Therefore, measure of angle ULE is 60°.

Answer:

La pendiente de la ecuación es -1.5 y su interpretación en el contexto del problema es que en este caso este valor indica que la longitud L de la vela luego de t horas desde que se encendió la decrece en 1.5 unidades por cada hora.

Step-by-step explanation:

La función lineal se define por la ecuación

f(x) = mx + b

o

y = mx + b

donde m es la pendiente de la recta y b es la ordenada al origen.

La gráfica de una función lineal es siempre una recta.

Como se mencionó, la m es la pendiente de la recta. La pendiente es la inclinación con respecto al eje x, que es el eje de abscisas.

La pendiente m significa que si aumentamos la x en una unidad, la y aumenta en m unidades. Si m es positiva (m > 0), entonces la función es creciente. En cambio, si la m es negativa (m < 0), entonces la función es decreciente.

En este caso, siendo L=1.5 - 1.5t y comparando con la expresión y=mx + b, podes observar que el valor de la pendiente m es -1.5. Como m es un número negativo, entonces se trata de una función decreciente. En este caso este valor de pendiente indica entonces que la longitud L de la vela luego de t horas desde que se encendió la decrece en 1.5 unidades por cada hora.

La pendiente de la ecuación es -1.5 y su interpretación en el contexto del problema es que en este caso este valor indica que la longitud L de la vela luego de t horas desde que se encendió la decrece en 1.5 unidades por cada hora.

Answer:

m∠1 = 55° ; m∠2 = 58°

Step-by-step explanation:

Let m∠1 = x° , then m∠2 = x° + 3°

m∠1 + m∠2 = 113°

x° + x° + 3° = 113°

2x + 3 = 113

2x = 110

x = 55°

m∠1 = 55° and m∠2 = 58°

The value of m∠[tex]1[/tex] is [tex]55[/tex]° and m∠[tex]2[/tex] is [tex]58[/tex]°

In the given figure m∠WXZ = [tex]113[/tex]° and m∠[tex]2[/tex] is [tex]3[/tex]° more than  m∠[tex]1[/tex].

What is angle?

An angle is formed when two rays are joined together at a common point.

Now,

Let  m∠[tex]1[/tex] = x° and m∠[tex]2[/tex] = x° + 3°

According to given figure;

m∠[tex]1[/tex] +  m∠[tex]2[/tex] = 113°

x° + x° + 3° = 113°

2x° + 3° = 113°

2x° = 110°

x° = 55°

Hence, the value of  m∠[tex]1[/tex] = x° = 55° and m∠[tex]2[/tex] = 55° + 3° = 58°

Answer:

f = 8 feet

Step-by-step explanation:

In Δ EBC

∵ DF ⊥ BE

∵ CB ⊥ BE

∴ DF // CB

∵ D is the mid-point of CE

∵ DF // CB

∴ F is the mid-point of EB

∵ DF joining the mid-points of EB and EC

∴ DF = [tex]\frac{1}{2}[/tex] CB

∵ CB = f and DF = 4 ft

∴ 4 = [tex]\frac{1}{2}[/tex] f

→ Multiply both sides by 2

∴ 8 = f

∴ The value of f is 8 ft

The true statements are:

1) The relationship is proportional

2) y = -3x is equation of the line.

3) The slope is negative.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction

A graph of the line is given.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

And line passes through the points (4, -12) and (6, -18).

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

m = -3

The slope is negative.

Then the equation of the line is,

y + 12 = -3(x -4)

y + 12 = -3x + 12

y = -3x

This equation shows the proportional relationship.

Therefore, all the required values are given above.
