Question

Write a system of equations for this situation. Currently, John has a collection of 32 CDs and William has a collection of 24 CDs. John is adding 1 CDs per month to his collection, while William plans to add 2 CDs per month. is it a or is it b
A.y = x + 32
y = 2x + 24
B.y = x + 24
y = 2x + 32

Answer 1

well what do you think you do first?

Answer 2

what do u mean..?

Answer 3

what do you think one of your equations will be? also you omited the actual question and only gave the background info I think

Answer 4

no i think i posted what i ment to post and i ment to post a question that has two awnesers to pick from simple as that

Answer 5

Let's focus on John

If x = # of months and y = # of CDs

then

y = 1x + 32

How did I get this? Well this is in y = mx+b form where m = 1 and b = 32

The slope is 1 because this is how much his CD collection is changing: he's adding 1 CD a month, so that's why the slope is 1

The y-intercept is 32 because this is the amount he starts with

Answer 6

So John's equation is

y = 1x + 32

which is the same as

y = x + 32

Answer 7

Because of your answer choices, you can easily see which one it is

but I recommend going through the same steps to find William's equation

Answer 8

ok thanks so much
