Question

@zepdrix Can you please help me?

Answer 1

With what? XD Post your question silly!

Answer 2

Janet told Sam that she has read 10 books this year and reads 2 books each month. Sam wants to catch up to Janet. He tracks his book reading with a table on his door. Using his table below, what month will Sam have read the same amount of books as Janet?

Answer 3

June is 3
July is 6
August 9

Answer 4

So it looks like, based on his chart, that sam is reading 3 books per month.

Janet is only reading 2 books per month ( but is 10 books ahead right now ),

so eventually sam will catch up.

Answer 5

This is the rate at which Janet is reading,
\[\Large\rm J(x)=2x+10\]Where x is the number of books each month.
2 books each month, plus 10 finished at the point where we start counting.\[\Large\rm S(x)=3x\]You can just call them J and S if the function notation is confusing.
I don't know if you've been introduced to that yet.

Answer 6

Not yet

Answer 7

So in 5 months, (plug in x=5)
J = 20
S = 15

So he hasn't quite caught up after 5 months.

To find out exactly when they have read the same amount,
we just set each function equal to one another.\[\Large\rm J=2x+10\]\[\Large\rm S=3x\]so we have:\[\Large\rm 2x+10=3x\]

Answer 8

oh i just did that on flvs lol

Answer 9

Solving for x tells us how many months it will take for them to read the same amount.
