Answers
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
Find f. Write your answer as a whole number or a decimal. DO NOT ROUND
Answers
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

Find the m∠ULE in the triangle below.
please
Answers
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°.

In the figure below, m angle WXZ=113°, and m angle2 is 3° more then m angle1 Find m angle1
Answers
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°

Find the perimeter
Answers
Answer:
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.

Which statement is true? Select all that apply.
Answers
The true statements are:
1) The relationship is proportional
2) y = -3x is equation of the line.
3) The slope is negative.
What is a slope?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.

Harper simplemente encendió una vela nueva y luego la dejó arder hasta la nada. La longitud de la vela que permanece sin quemar, en pulgadas, se puede modelar mediante la ecuación L = 15-1.5t, L = 15−1.5t, donde tt representa el número de horas desde que se encendió la vela. ¿Cuál es la pendiente de la ecuación y cuál es su interpretación en el contexto del problema?
Answers
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.
