Question

Missy is organizing the seating arrangements for a concert in her local park. The first row's seats are modeled by the function f(x) = 10. To give everyone a good view, each row must have two more seats than the row before it. The number of additional seats a row has is modeled by the function s(x) = 2(x - 1).

Explain to Missy how to create an equation to predict the number of seats in any row. Describe how to determine the number of seats in the 20th row. Use complete sentences.

Answer 1

@Abhisar @Luigi0210 or @paki please hep me ): so confused

Answer 2

Do you know the equation?

Answer 3

no ): completely lost its like s(x)=(1-1) something like that

Answer 4

ok so fx=10 thats the first part of your equation
\[x=10\]

Answer 5

like I don't know what numbers to plug in and what number to multiply and subtract to get my answer in a non confusing way

Answer 6

oh im confused i go the equation but i dont know if i got it right because i got a = 10 + (19)2
because fx=10 and then since shes in the 20th row you plug in \[s(x)=2(20-1)=~x=10+19(2)\]

Answer 7

im pretty sure thats correct and now you just have to solve

Answer 8

Do you get that?

Answer 9

Pooja why do you hate me \[D:\]

Answer 10

@izthewiz7 are you understanding what i said?

Answer 11

I honestly don't understand this..... this is really depressing me, I've been on the same freaking question )):

Answer 12

ok lets do this step by step
\[x=10\] you know this info already
\[s(x) = 2(x - 1)\] this is the formula given to find the number of additional seats
\[s(x)=2(20−1)\] we plug in 20 because that the only info you have on the seats disregarding the numbers 2 and all of that
\[s(x)=2(20−1)= x=10+19(2)\] combine the solution of the equation with x=10
\[x=10+19(2)\] solve the equation to get answer

Answer 13

Ik how you feel, Ive been on open study for two days and I know right now you just want the answer. You don't care about how you get it. I know you can get stuck on one question for a long time, but I assure you. Once you earn the answer and you get the feeling of accomplishment it Is so worth it. :) Just hang in there

Answer 14

@izthewiz7 do you get it now?

Answer 15

@pooja195 48? and @EinsteinPart2 yeah, I've been on this problem for 2 hours, I just need to understand because I kave another question like this /:

Answer 16

No its not 48 you did something wrong

Answer 17

I give up /: thanks though, I really appreciate it..

Answer 18

no dont give up you just have to solve that last equation :D come on you can do it :D

Answer 19

I get so confused at the part of when you got to s(x)= 2(20-1) = x = 10 + 19(2)
