Answer:
192 feet is the stopping distance at 48 mph.
Step-by-step explanation:
Set up the proportion
x/75 = 2304/900 cross multiply to get 900x = 172800
172800 ÷ 900 = 192
x = 192
1 mile = 5280 feet
81 * 5280 = 427680 feet per hour
1 hour = 3600 seconds
427680 / 3600 = 118.8 feet per second
118.8 * 15 = 1782 feet in 15 seconds
Answer:
Yes
Step-by-step explanation:
The way the equation is written in point-slope form is:

The way we write an equation in slope-intercept form is:

We can change point-slope form to slope-intercept form by first distributing the m and then adding y1 to both sides of the equation. When we do this we will get:
where
which is now in slope intercept form.
I think that's the answer
