13x - 5y (if x = 10 and y = 6)​

Answers

Answer 1

Answer:

13(10) - 5 (6)

130 - 30

= 100

Step-by-step explanation:

You replace the x with 10, and the y with 60 and answer normally

13(30) = 130

5(6) = 30

130 - 30 = 100

Answer 2
The answer would be 130x-30y

Andre and Diego were each trying to solve `2x+6=3x-8`. Describe the first step they each make to the equation.



The result of Andre's first step was `-x+6=-8`.

Answers

He subtracted 3x from both sides. the next step would be to subtract 6 from -8 which would leave you with -x=-14 now you divide -14 by -x (-1) and you’ll get 14. x=14

Step-by-step explanation:

This is not a function because every x value has more than one y value. Think about it this way. If you have a person and you are telling them to go to three different places at once, they can't. That means this isn't a function. Hope this helps!

Answer: That is not a function

En cierto cultivo, inicialmente había 1000 amebas que se reproducen por biparticion cada día ¿Cuántas amebas habrá al cabo de 30 días después que se inició el cultivo ?

Answers

Answer: 1,073,741,824,000 amebas

Step-by-step explanation:

Bipartición significa que la población de amebas se duplica cada día.

Entonces si inicialmente hay 1000, después de un día van a haber:

2*1000.

Después del segundo día se vuelven a duplicar, entonces van a haber:

2*(2*1000) = (2^2)*1000

Después del tercer día, lo mismo:

2*(2^2)*1000 = (2^3)*1000.

A esta altura ya se puede ver el patrón, podemos concluir que después de N días, la población de amebas va a ser:

P(N) = (2^N)*1000.

Entonces respondiendo a la pregunta:

¿Cuántas amebas habrá al cabo de 30 días después que se inició el cultivo?

Tenemos que tomar N = 30

P(30) = (2^30)*1000 = 1,073,741,824,000 amebas

Find an expression for the nth term (tn) in each of the following sequence:

2, 6, 10, 14, 18…

Answers

Answer:

The answer is 34

Step-by-step explanation: I just have a big brain

Answer: [tex]t_n = 4n - 2[/tex]

===========================================

Work Shown:

The first term is a = 2 and the common difference is d = 4, since we're adding 4 to each term to get the next term.

[tex]t_n = \text{nth term of arithmetic sequence}\\\\t_n = a+d(n-1)\\\\t_n = 2 + 4(n-1)\\\\t_n = 2 + 4n - 4\\\\t_n = 4n - 2[/tex]

Which is the answer.

--------------------------------

If you were to plug in say n = 3, then we get

[tex]t_n = 4n - 2\\\\t_3 = 4(3) - 2\\\\t_3 = 12 - 2\\\\t_3 = 10[/tex]

showing that 10 is the third term, which matches with what the original sequence shows. I'll let you check the other values of n to fully confirm the answer.
