If we notice, the decrease in payment after 3 and 5 months, it is a multiple of 150.

So, the equation that models balance b after m months is:

b = 1800 - 150m

Here, - 150 is the slope and it indicates the amount being decreased every month.

Answer:

balance (b) = 1800 - 150m, where "m" is the number of months.

Step-by-step explanation:

Zachary purchased a computer for 1800 on a payment plan.

After 3 months, his balance = 1350

Reduced amount = 1800 - 1350 = 450

So, 1 month payment = 450 ÷ 3 = 150

After 5 months, his balance = 1050

The reduced amount = 1800 - 1050 = 750

So, 1 month payment = 750 ÷ 5 = 150

Therefore, the rate of change = -150. It is negative because the amount getting reduced.

Therefore, the model is

balance (b) = 1800 - 150m, where "m" is the number of months.

Simon says "five time my age 4 years ago is the same as three time my age in 2 years" how old is simon
omeli [17]

Simon is 13 years old

Let x be Simon's age

Thus 4 years ago his age was (x - 4) and 2 years from now his age is (x + 2)

Hence 5(x - 4) = 3(x + 2)

distributing both sides gives

5x-20 = 3x + 6

subtract 3x from both sides of the equation

5x - 3x - 20 = 6

2x - 20 = 6

add 20 to both sides

2x = 6 + 20 = 26

divide both sides by 2

x = \frac{26}{2} = 13

Simon is 13 years old
