Domain are x values (independent variable);

Speed would be independent so what speeds can be used ? -30 mph, 30 mph, 1000 mph?

Can a car go 0 mph?

What is realistic?

I would say 0 greater or equal to x greater than whatever you think is beyond the max that a car can go.

3241004551 [841]

Answer:

m^2-3m-180=0

m=15

Step-by-step explanation:

greater integer = m

small integer = n

we know that m = n+3 or n = m-3

we also know that n*m = 180

replace n for m-3

(m-3)*m=180

or

m^2-3m-180 = 0

(m-15)(m+12)=0

so m = 15 or -12, but since problem states positive, m=15

3. Write the following equation in slope intercept form: -2x + y = 9 A.) Y = -2x + 9 B.) Y = -2x – 9 C.) Y = 2x + 9 D.) Y = 2x –
Ira Lisetskai [31]

Hey! :)

So when we write something in slope intercept form, all we're doing is solving for y. So let's do that with this equation!

-2x + y = 9

add 2x to both sides

y = 2x + 9

So C is your answer.

Please let me know if you need anything further explained!
