Answer: 3/32
Step-by-step explanation:
Here's the complete question:
Helen used 1/4 of her savings for her first year of college. 3/8 of that money was spent on her housing and meals. Which equation shows the fraction of her total savings that was spent on her housing and meals?
Since we are told that Helen used 1/4 of her savings for her first year of college and that 3/8 of that money was spent on her housing and meals.
To calculate the fraction of her total savings that was spent on her housing and meals, we would multiply 1/4 by 3/8. This will be:
= 1/4 × 3/8
= 3/32

Respuesta:
El punto A(-3, 3) pertenece a la recta.
El punto B(0, -15) no pertence a la recta.
Explicación paso a paso:
Consideremos la siguiente ecuación de la recta en forma estandar.
-4x - y + 15 = 0
Para verificar si los puntos A y B pertencen a la recta, primero la transformaremos a la forma explícita.
-4x - y + 15 = 0
-4x + 15 = y
y = -4x + 15
El punto A(-3, 3), tiene coordenada x -3 y coordenada y 3. Reemplazaremos x en la ecuación de la recta y veremos si obtenemos el mismo valor de y.
y = -4(-3) + 15 = 3
El punto A(-3, 3) pertenece a la recta.
El punto B(0, -15), tiene coordenada x 0 y coordenada y -15. Reemplazaremos x en la ecuación de la recta y veremos si obtenemos el mismo valor de y.
y = -4(0) + 15 = 15
El punto B(0, -15) no pertence a la recta.

Answer:
Step-by-step explanation:
Coordinate points: (18, -7) and (18,2)
m= rise / run or 
m = slope
(x1, y1) = coordinates of first point in the line
(x2, y2) = coordinates of second point in the line
So your rise is...
2 - (-7)
and you run is...
18 -18
Rise = 9
Run = 0
Now, do you see the issue...
You can not have a number over 0 (* a great way to remember is N/0 spells no: "N" being number and "0" being zero)
The slope or the equation 9 / 0 (9 divided by 0 or 9 over 0) is ERROR in the calculator which means the slope of these points are undefined
The line is vertical when this happens
*Side Note: if you were to have 0 as you rise and 9 as your run, 0/9 is ok because that means you have a zero slope meaning that you have a horizontal line
0 divide by 9 is zero
