Welcome to OpenStudy! What's your question? :)

Answer 2

oh let me get it

Answer 3

Cheyanne is saving for a car. The amount she has saved for the car, f(x), can be represented by the function f(x) = 65x + 750, where x is the number of weeks she has saved. Suppose 750 changed to 700. What does this mean in the context of the problem?

Changing 750 to 700 means the initial amount she saved decreased.
Changing 750 to 700 means the initial amount she saved increased.
Changing 750 to 700 means the amount she saves each week decreased.
Changing 750 to 700 means the amount she saves each week increased.
I picked the last one but idk if its correct

Answer 4

750 or 700 is the constant

That's the amount she has already saved

65 is the amount she will be saving every single week

so what do you think the answer will be? :)

Answer 5

last answer choice

Answer 6

no, the amount she saves each week is modelled by 65x since x is how many weeks she is saving for

the first week she saves a total of 65 * 1 = 65 dollars
in two weeks she saves a total of 65 * 2 = 130 dollars

Answer 7

first choice?

Answer 8

and then you have to add whatever she had already saved up which is 750

but you're making that now 700

what answer choice does that make it? :P

Answer 9
