A line goes through the points (8,9) (-2,4)
SIZIF [17.4K]

Answer:

y-9=1/2(x-8)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(4-9)/(-2-8)

m=-5/-10

m=1/2

y-y1=m(x-x1)

y-9=1/2(x-8)

Antonio, Lucas y Darío compraron un refresco de 5/2 (2litros y 1/2) que piensan repartir en partes iguales. a) ¿Qué fracción de
Elanso [62]

Answer:

a) A Antonio, Lucas y Darío le corresponde cada uno \frac{5}{6} litros.

b) Antonio, Lucas y Benjamín deben convidar cada uno \frac{5}{24} litros.

Step-by-step explanation:

a) Antonio, Lucas y Darío compraron un refresco, el cual reparten en tres partes iguales. Por tanto, la fracción de litro para cada persona es la capacidad del refresco dividido por el número de personas. Es decir:

x = \frac{\frac{5}{2}\,L }{3}

x = \frac{5}{6}\,L

A Antonio, Lucas y Darío le corresponde cada uno \frac{5}{6} litros.

b) En primer lugar calculamos la fracción correspondiente a cuatro personas:

x = \frac{\frac{5}{2}\,L }{4}

x = \frac{5}{8}\,L

Ahora, procedemos a calcular la diferencia entre el escenario calculado en a) y el resultado anterior:

\Delta x = \frac{5}{6}\,L-\frac{5}{8}\,L

\Delta x = \frac{40-30}{48} \,L

\Delta x = \frac{10}{48}\,L

\Delta x = \frac{5}{24}\,L

Este resultado corresponde a la fracción que Antonio, Lucas y Darío deben convidar cada uno a Benjamín. Entonces, Antonio, Lucas y Benjamín deben convidar cada uno \frac{5}{24} litros.

Which relationships describe angles 1 and 2?
Alenkasestr [34]

Answer:

Adjacent angles

complementary angles

Step-by-step explanation:

Adjacent angles are two angles that have a common side and a common vertex (corner point) but do not overlap in any way. When you break down the phrase adjacent angles, it becomes easy to visualise exactly what it is; they are two angles that are next to each other.  

If the measure of two angles add up to 90 degrees the angles are called "complementary angles". For example, A = 30. o. and B = 60.

Write the equation of the line that passes through the points (-3,2) and (-1,6)
Dmitrij [34]

Answer:

y=2x+8

Step-by-step explanation:

An equation that is most suitible for this kind of problem is the slope intercept form with is y=mx+b.

m=slope

b=y-intercept

1: Find the slope

Use the formula y2-21/x2-x1

6-2/-1-(-3)=4/2=2

m=2

2: Find the y-intercept

For me personally, I think it is easiest to just graph the points, draw the line, then find where the line meets the y-axis.

b=8

<u>y=2x+8</u>

<em>Hope this helped! Brainliest would be awesome :)</em>
