( $x_{1}$ , $y_{1}$ )

( $x_{2}$ , $y_{2}$ )

rate of change or slope m = $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$ = $\frac{rise}{run}$

y = mx + b

"b" is y-intercept

How do I write 575 as a mixed number

Nookie1986 [14]

A mixed number is a whole number plus a fraction.

575 is just a whole number, without a fraction. If you absolutely must have
a mixed number, then you have to create a fraction out of 575 somehow.

This is going to look pretty silly, but I guess you could take ' 1 ' away from 575,
and use it to make a fraction, like 1/1 .

Then your mixed number could be 574 and 1/1 .

Isn't that ridiculous ? ! ?

Answer:

<u>Hannah was not speeding because her speed was about 61 mph, which is below the speed limit.</u>

Explanation:

Just to correct some typos, this is the complete question:

<em />

<em>The equation d=0.05v² + 1.1v models the distance, d, that it takes a car traveling at a speed of v miles per hour to come to a complete stop. If Hannah’s car stopped after travelling 250 feet on a highway with a speed limit of 65 mph, was Hannah speeding? Explain using math whether she was speeding and how you know.</em>
