Answer:
Step-by-step explanation:
Let the number of months = x
It is given that,
Carson deposits $70 each month and has $450 in his bank account.
So, the initial deposit is $450 and monthly deposit is 40x.
Let Carson's bank balance = y (in dollars).
Thus, the linear function representing the bank balance is,
Let’s find the unit rate of the problem
If we divide both $15 and 3 by 3 we get $5 and 1.
That means every package costs $5, so the COP or k =5
b. Using 5 as the k in y=kx, the equation is y=5x
Answer:
the top two
Step-by-step explanation:
For a function to be invertible, it must pass the "horizontal line test." That is, there can be no horizontal line that will intersect the graph in more than one place. The bottom two graphs fail this test, so do not represent invertible functions.
The two top graphs show invertible functions.
