What is an equation of the line that passes through the point (1, -2) and is parallel

Mathematics
1 answer:
Oliga [24]3 years ago
6 0

Answer:

y = -6x + 4

Step-by-step explanation:

2 parallel lines should have equal slope

Rewrite 6x + y = 92

It is now y = -6x + 92. Slope is -6

So the new equation should also have -6 as the slope.

y = -6x + b

Substitute (1,-2) into this equation

-2 = -6(1) + b

-2 = -6 + b

4 = b

So equation is y = -6x + 4

Explicație pas cu pas:

Care este cel mai mic număr între 95.999; 96.959; 99.595 și 99.995, unde numărul de mii este 5

95.999 = Nouăzeci și cinci de mii nouă sute nouăzeci și nouă

96.959 = Nouăzeci și șase de mii nouă sute cincizeci și nouă

99595 = Nouăzeci și nouă de mii cinci sute nouăzeci și cinci

99995 = Nouăzeci și nouă de mii, Nouă sute nouăzeci și cinci.

The ratio of boys to girls at the beach cleanup was 7:8. If there were 42 boys, how many girls were there?
lesantik [10]

It would be 48 girls. 42 divided by 7 equals 6 so then you just times 6 by 8 to figure out how many girls there will be.

PLEASE HELP FAST!! WILL MARK BRAINLIEST!!!!
Aleonysh [2.5K]
In 4 days Bryn sells 24 tickets (50-26)
So in 1 day he sells 6 tickets --> B is right
The +33 in the equation means, that Eddie sold 33 tickets oon the first day
--> So C.) and D.) are right
When you replace the x in the equation with 1, you'll get the tickets, that eddie sold on the first day. --> y = 5 *(1)+33 = 38
38 tickets - 33tickets = 5 tickets ( the rise)
-->A.) is wrong, because Bryn sold two tickets more as Eddie per day

solo el 20% de los empleados de la población civil que está en una base militar restringida porta su identificación personal. Si
prisoha [69]

Usando la distribución binomial, hay una probabilidad de 0.8926 = 89.26% de que el guardia de seguridad encuentre al menos uno en la base militar restringida.

<h3>¿Qué es la distribución binomial?</h3>

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

C_{n,x} = \frac{n!}{x!(n-x)!}

Los parámetros son:

  • n es el número de ensayos.
  • p es la probabilidad de éxito en un ensayo
  • x es el número de éxitos

En este problema, hay que:

  • 20% de los empleados de la población civil que está en una base militar restringida porta su identificación personal, o sea p = 0.2.
  • Llegan 10 empleados, o sea, n = 10.

La probabilidad de que el guardia de seguridad encuentre al menos uno en la base militar restringida es dada por:

P(X \geq 1) = 1 - P(X = 0)

En que:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 0) = C_{10,0}.(0.2)^{0}.(0.8)^{10} = 0.1074

Por eso:

P(X \geq 1) = 1 - P(X = 0) = 1 - 0.1074 = 0.8926

Hay una probabilidad de 0.8926 = 89.26% de que el guardia de seguridad encuentre al menos uno en la base militar restringida.
