Vanessa purchased a smart TV for $1,500 on a payment plan. Four months after purchasing the TV, her balance was $1,200. 7 months after purchasing the TV, her balance was $975. Find an equation that models the balance B(t) after t months. How many months will it take her to pay off the TV loan?

B(t) = 1500 - 75(t)

It will take her 20 months to pay off her debt.

Step-by-step explanation:

Vanessa purchased a smart TV for $1500 on a payment plan. 4 months after purchasing the TV her balance was $1200. This means for the 4 months period she paid $300 . This simply translate to her paying $75 each month for the 4 month duration.

7 months after her balance was $975 . For 7 months duration her balance was $975 which simply means she paid 7 × 75 = $525 during the 7 months period.

The equation to model the balance B(t) after t months can be represented below.

Each month she pays $75 to dislodge her debt. For t months her balance will be

B(t) = 1500 - 75(t)

The number of month it will take her to pay off her loan means her balance will be $0.

B(t) = 1500 - 75(t)

-1500 = -75t

t = -1500/-75

t = 20

It will take her 20 months to pay off her debt.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
