x = number of minutes
y = amount of rope uncoiled
At first we have 50 feet of uncoiled rope. So basically at time x = 0 we have y = 50 feet of uncoiled rope. The point (0,50) is on the line. After 5 minutes, 5*10 = 50 feet of rope is coiled up, as its coiled at 10 ft/min. After these 5 minutes, we have 0 feet of uncoiled rope. The point (5,0) is on the line.
The line goes through (0,50) and (5,0)
Now go through the window options and see which provide the right window to be able to see the line segment with the endpoints mentioned.
- Choice A = yes, because y = 50 is part of the interval
![0 \le y \le 75](https://tex.z-dn.net/?f=0%20%5Cle%20y%20%5Cle%2075)
- Choice B = yes, similar reasons as choice A
- Choice C = no, due to the fact that y = 50 is too large and outside the interval
![0 \le y \le 10](https://tex.z-dn.net/?f=0%20%5Cle%20y%20%5Cle%2010)
- Choice D = no, same reasoning as choice C
<h2>Greetings!</h2><h3>Firstly, the slope is found by rearranging the formula:</h3>
3y = 4x + 39
y =
+ ![\frac{39}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B39%7D%7B3%7D)
When x is 0, y = 0(x) +
, so the y intercept is ![\frac{39}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B39%7D%7B3%7D)
<h3>Next, the slope is simply the number in front of the x, </h3>
So
can be rearranged to
, so the slope would be
.

Answer: Identity Property
Step-by-step explanation:
The rest have very fake names lol
We gots a triangular prism+ rectangular prism
easiest way is base times heigth and treat the triangle+rectangle on the side as the base
so
find the area of the side
the rectangle bit is area=7.5 times 7=52.5
the triangle bit is 1/2 times 7.5 times 7=26.25
total area is 52.5+26.25=78.75
and the height is 8
volume=8 times 78.75=630 cubic feet
answer is C
