Elena L [17]3 years ago

Answer:

y=1/4x+2.75

Step-by-step explanation:

two coordinates are: (5,4) and (-3,2)

the linear function is y=mx+b

m=slope

b=y-intercept

first, find the slope

the formula to find the slope is y2-y1/x2-x1

2-4/-3-5=

-2/-8=

1/4

Now you know 1/4 is the slope.  Plug that into the function

y=1/4x+b

Now find the y-intercept

to do that, take one of your coordinates and plug the x and y values into the function.

I will use (-3,2)

2=1/4(-3)+b

2=-3/4+b

11/4=b

(or 2.75 decimal form)

Plug the y-intercept into the function and you're done

y=1/4x+2.75

Una persona camina 7 kilómetros hacia el norte, después 3 kilómetros hacia el este y, luego, 3 kilómetros hacia el sur. ¿A qué d
qaws [65]

Answer:

La persona está a 5 kilómetros con respecto al punto de partida.

Step-by-step explanation:

Considérese que la dirección norte coincide con el semieje +y y que la dirección este coincide con el semieje +x. A continuación, obtenemos las formas vectoriales equivalentes de cada afirmación:

(i) Una persona camina 7 kilómetros hacia el norte:

\vec r_{1} = 7\,\hat{j}\,[km]

(ii) Después 3 kilómetros hacia el este:

\vec r_{2} = 3\,\hat{i}\,[km]

(iii) Y luego, 3 kilómetros hacia el sur:

\vec r_{3} = -3\,\hat{j}\,[km]

El vector resultante de desplazamiento se construye a partir de la siguiente suma de vectores:

\vec R = \vec r_{1}+\vec r_{2} + \vec r_{3} (1)

\vec R = 3\,\hat{i} + 4\,\hat{j}\,[km]

Asumiendo que la distancia coincide con el desplazamiento resultante, calculamos la distancia con respecto al punto de partida mediante el Teorema de Pitágoras:

\|\vec R\| = \sqrt{3^{2}+4^{2}}

\|\vec R\| = 5\,km

La persona está a 5 kilómetros con respecto al punto de partida.

Determain the equation, in slope intercept form, of the line of the line that has a slope of -6 and passes through the point P(-
Vinil7 [7]

Answer:

<h2>         y = -6x - 16</h2>

Step-by-step explanation:

The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:

m = -6

(-3, 2)    ⇒   x₀ = -3,  y₀ = 2

The point-slope form of the equation:

y - 2 = -6(x + 3)

So:

y - 2 = -6x - 18         {add 2 to both sides}

y = -6x - 16             ←  the slope-intercept form of the equation

Andrea constructed a triangle. Angle 1 and 3 are the same size and angle 2 has a measurement of 70 degrees. What is the measurem
Verdich [7]

Answer:

Step-by-step explanation:

By triangle sum theorem,

Sum of all angles of a triangle is 180°.

m∠1 + m∠2 + m∠3 = 180°

(m∠1 + m∠3) + m∠2 = 180°

2(m∠1) + 70° = 180° {Given → m∠1 = m∠3]

2(m∠1) = 110°

m∠1 = 55°

Therefore, m∠1 = m∠3 = 55°

CAN SOME ONE HELP ME ITS URGENT
aniked [119]

As we can observe from given information,

  • UT = ST

  • 2x + 5 = x + 12

  • 2x - x = 12 - 5

  • x = 7

now, let's solve for y

  • RU = RS

  • y - 4 = x + 5

  • y - 4 = 7 + 5

  • y = 12 + 4

  • y = 16

hope it helped...
