↓↓

Step-by-step explanation:

The original value of the cellphone is $650. The function represents an exponential decay because if it was exponential growth, the function would look like this:

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

40 minutes

step-by-step explanation:

add the time and multiply by 2
