y = -4x - 1

It is a linear function different from the constant function. Therefore, if the range is only one number, then the domain is only one number too.

Let's calculate it:

y = -25 → -4x - 1 = -25 |add 1 to both sides

-4x = -24 |divide both sides by (-4)

x = 6

Answer: The domain = {6}.

The product of a fraction and its multiplicative inverse is 1. True or False. Explain

natima [27]

True.....I am not really good at explaining, but I would try. for any fraction , if it is multiplied by it inverse it equals to one because they end up crossing out. example: 3/4 ×4/3=1
6/23×23/6=1

Answer:

No, This is not reasonable estimate.

Step-by-step explanation:

Charles wants to take out a 5 year loan on car that cost $15000.

He make rough estimate to make payment. He can afford to pay up to $200 per month.

First we find total number of months in 5 years.

Total months = 5x12= 60 months

Total estimate to pay = $60\times 200$ =$12000

we can see cost of a car $15,000 is greater than his estimation $12,000.

Therefore, Charles estimation will not work.

No, This is not reasonable estimate.
