mariah owed her grandfather $2.25 but was only able to pay him back 1.50 , how much does mariah currently owe her grandfather
aleksandr82 [10.1K]

Answer:

0.75 cents

Step-by-step explanation:

You take...

$2.25 and subtract $1.50 to get 0.75 cents

In-depth...

Start off with taking a dollar away...

2.25 - 1.00 = 1.25

Then take off 0.50 cents...

We know that 0.50 cents are two 0.25 cents

So, we take off one 0.25 cent

1.25 - 25 = 1.00

Then the next 0.25 cents

*Remember: twenty-five (.25), fifty (.50), seventy-five (.75), a dollar (1.00)

<--- it is just adding 25 each time

If we subtract 0.25 cents from a dollar we get...

0.75 cents

If the factors of a quadratic function are (x + 2) and (x − 9), what are the x-intercepts of the function?
Zielflug [23.3K]

Answer: D. (-2,0) and (9,0)

Step-by-step explanation:

When you equate the factors to 0 you get

(X+2) = 0

X = -2

(X-9) = 0

X= 9

Here the Y value is 0 as you find the factors of x when the Y value is 0.

So the answer is (-2,0) and (9,0)
