Write the equation of the line that passed through the point (-1,-4) that is perpendicular to the line

у -2 +1.
Show all of your work and answer in the text box provided.
Answer:
The line that meets these conditions is y = 1.5x - 2.5
If you want to use fractions, it would be y = 3x/2 - 5/2
Step-by-step explanation:
To get a line perpendicular to y = -(2/3)x + 1, We can start by finding its slope. That's easy enough as a perpendicular slope is the negative reciprocal of the given one. As this has a slope of -2/3, our new slope has to be 3/2, or 1.5
All we need to do then is express that rate of change relative to the given point (-1, -4). We can do this by expanding the classic equation:
Δy = sΔx
We can write that as such:
y - (-4) = 1.5(x - (-1))
y + 4 = 1.5(x + 1)
y + 4 = 1.5x + 1.5
y = 1.5x + 1.5 - 4
y = 1.5x - 2.5
Or if you want to express those numbers as fractions, it would be y = 3x/2 - 5/2.
To make sure the answer's correct, we can simply plug -1 in as the x value, and see if we get y = -4:
y = 3(-1) / 2 - 5/2
y = -3 / 2 - 5 / 2
y = -8 / 2
y = -4
So we know that our answer is correct (assuming that the slope is correct, which it is - a perpendicular line always has the negative reciprocal of the other line's slope).

At an average internet speed of 15 mbps, a computer takes 4 minutes to
download an application file. If the speed slows down to 10 mbps, how
long does the computer take to download the file?
Answer:
6 minutes
Step-by-step explanation:
Speed of net = 15mbps
Time taken = 4min.
Total size of application= 15*60*4= 3600mb
Now speed = 10mbps
Time taken = 3600/10
= 360 sec = 360/6 min
= 6 min

y=4x+3
2x-3y=21
SHOW YOUR WORK
Step-by-step explanation:
y = 4x+3
2x-3y = 21
2x -3(4x+3) = 21
2x -12x -9 = 21
-10x = 21 + 9
-10x = 30

En la clase de matematicas hay un total de 50 alumnos han aprobado el 80% ¿Cuántos alumnos han reprovado
Responder:
10
Explicación paso a paso:
Dado que:
Número total de estudiantes = 50
Porcentaje que pasó = 80%
Si pasó el 80%;
luego porcentaje que falló:
(100 - 80)% = 20%
Número que falló:
20% del total de estudiantes
0,2 * 50
= 10 estudiantes reprobaron

1.When two variables are proportional which of the following is constant?
(1) their sum
(3) their product
(2) their ratio
(4) their difference
Answer:
Their Ratio
Step-by-step explanation:
You switched the numbers 2 and 3 btw
[tex]\boldsymbol{\left ( 2 \right )}[/tex] their ratio
A ratio indicates how many times one number contains another.
Two sequences of numbers, often experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, which is called the coefficient of proportionality or proportionality constant.
When two variables are proportional, [tex]\boldsymbol{\left ( 2 \right )}[/tex] their ratio is constant.
