Answer:
It seems that the slope of this line is 1/5, yet none of the answers correspond to this. Double-check by finding two points on the line, and use the slope formula: (y2-y1/x2-x1). Also, remember that slope is rise/over run. I hope this can guide you!
Answer: the answer is not included in the options
Step-by-step explanation:
The slope of the line can be depicted by the following formulas: 1. Rise/run 2. Y1-y2/ x1-x2
If we were to use the second formula and “plug” in numbers for the variables, the slope we calculate is less than 1

The money collected from a Saturday car wash are directly proportional to the number of cars washed. The total money collected after 7 cars is $140. Write an direct variation equation relating the money collected (m) and the number of cars washed
Answers
Answer:
[tex]m=20c[/tex]
Step-by-step explanation:
Let m represent the total money collected and c represent the amount of cars washed.
We know that the money collected is directly proportional to the number of cars washed. So, we can write the following equation:
[tex]m=kc[/tex]
Where k is a constant.
We know that the money collected after 7 car washes is $140. So, let's find our k by substituting 140 for m and 7 for c. This yields:
[tex]140=7k[/tex]
Find k. Divide both sides by 7:
[tex]k=20[/tex]
So, the value of k is 20.
We can now substitute k back into our direct variation equation:
[tex]m=20c[/tex]
This means that every car costs $20 to wash.
And we're done!

Step-by-step explanation:
Agustín y Bárbara salen al mismo tiempo y del mismo lugar, por el mismo camino. Agustín camina a 5km/h y Bárbara a 3km/h. Luego de recorrer 7km, Agustín emprende el regreso, ¿a qué distancia de la partida se encuentra con Bárbara? Si en el momento del encuentro también Bárbara emprende el regreso, ¿cuántos minutos después que Agustín llega Bárbara al punto de partida?
Answers
Answer:
Ok, primero Agustín camina a 5km/h.
Cuando el recorre 7km, el regresa.
El tiempo en el que sucede esto es a:
7km/5km/h = 1.4 h
La ecuación para Agustín es:
A(t) = 5km/h*t para 0h ≤ t ≤ 1.4h (ida)
A(t) = 7km - 5km/h*(t - 1.4h) para 1.4h ≤ t. (vuelta)
Hacemos lo mismo para Barbara:
7km/3km/h = 2.5h
La ecuación para ella es:
B(t) = 3km/h*t para 0h ≤ t ≤ 2.5h (ida)
B(t) = 7km - 3km/h*(t - 2.5h) para 2.5h ≤ t. (vuelta)
a) ¿a qué distancia de la partida se encuentra con Bárbara?
Tenemos que ver cuando A(t) = B(t).
Para ello comparamos la vuelta de Agustín con la ida de Barbara.
7km - 5km/h*(t - 1.4h) = 3km/h*t
7km - 5km/h*T + 7km = 3km/h*T
14km = 8km/h*t
14/8 h = 1.75h = t.
Entonces la posición en la que se encuentran es:
B(1.75h) = 3km/h*1.75h = 5.25km
Ellos se encuentran a 5.25 kilómetros de el punto de partida.
b) Si en el momento del encuentro también Bárbara emprende el regreso
(Es decir, en este momento Barbara comienza a regresar).
Entonces ella para regresar al punto de inicio tiene que recorrer 5.25km con una velocidad de 3km/h.
Tb = 5.25km/3km/h = 1.75h
Barbara tarda 1.75 horas en regresar.
Agustín también tiene que recorrer 5.25 km para regresar, pero su velocidad es 5km/h.
Ta = 5.25km/5km/h = 1.05h.
La diferencia entre los tiempos es:
Tb - Ta =1.75h - 1.05h = 0.7h
Entonces Barbara llega al punto de partida 0.7 horas después que Agustín.
Pero queremos esto en minutos.
1 hora = 60 minutos.
0.7 horas = 0.7*(60 min) = 42min
Barbara llega 42 minutos después que Agustín.

how do I solve this equation 5x+7=3x-5
Answers
Answer:
x = -6
Step-by-step explanation:
Simplifying
5x + 7 = 3x + -5
Reorder the terms:
7 + 5x = 3x + -5
Reorder the terms:
7 + 5x = -5 + 3x
Solving
7 + 5x = -5 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
7 + 5x + -3x = -5 + 3x + -3x
Combine like terms: 5x + -3x = 2x
7 + 2x = -5 + 3x + -3x
Combine like terms: 3x + -3x = 0
7 + 2x = -5 + 0
7 + 2x = -5
Add '-7' to each side of the equation.
7 + -7 + 2x = -5 + -7
Combine like terms: 7 + -7 = 0
0 + 2x = -5 + -7
2x = -5 + -7
Combine like terms: -5 + -7 = -12
2x = -12
Divide each side by '2'.
x = -6
Simplifying
x = -6
The solution to the equation 5x + 7 = 3x - 5 is x = -6.
We have,
To solve the equation 5x + 7 = 3x - 5, we need to isolate the variable x on one side of the equation.
Here's how we can do that:
Start by subtracting 3x from both sides of the equation to move all the x terms to one side:
5x + 7 - 3x = 3x - 5 - 3x
Simplifying, we get:
2x + 7 = -5
Next, subtract 7 from both sides of the equation to isolate the term with x:
2x + 7 - 7 = -5 - 7
Simplifying, we get:
2x = -12
Now, to solve for x, we divide both sides of the equation by 2:
(2x)/2 = (-12)/2
Simplifying, we get:
x = -6
Thus,
The solution to the equation 5x + 7 = 3x - 5 is x = -6.

Derek can do 50 pushups. Roger can do

Answers
Answer: 40
Step-by-step explanation: 50x0.8=40
Okay, maybe im wrong? But i dont see how its 4 thats more than half.
Rodger can do 46 pushups.
50 * 0.92 = 46
Edit: To better clarify, 0.92 is from 1.00 - 0.08.
... 8 percent fewer than 100 percent is 92 percent; 1.00 - 0.08 = 0.92
Keep in mind that:
1.00 = 100%
0.08 = 8%
0.92 = 92%
After finding this you may multiply 50 * 0.92 to get 46.
