Δy/Δx is nothing but the slope and slope = rise/run .

Look up in the FIRST graph; From the lower point on the line draw a // to x-axis and from the higher point draw a // to y-axis. Note the point of intersection, their coordinates are (6, 3) [ x=6 = run and y= 3 = rise)
Or Δy = rise = 6    and Δx = run = 3, hence Δy/Δx  = 6/3 = 1/2 = slope.

Do the same thing with the 2nd graph:
Δy = 3 and  Δx = - 2 (you are counting from right to left), then 

Δy/Δx = 3/(-2)  and Δy/Δx = -3/2

Find the derivative of the inverse function of the original function f(x)=(x+1)^3-5
____ [38]

Answer:

Step-by-step explanation:

let f(x)=y

y=(x+1)^{3} -5\\flip ~x~and~y\\x=(y+1)^{3}-5\\(y+1)^{3}=x+5\\y=(x+5)^{\frac{1}{3} } -1\\or~f^{-1}(x)=(x+5)^{\frac{1}{3} } -1\\(f^{-1})'(x)=\frac{1}{3} (x+5)^{\frac{-2}{3} }

How do you round 25.691 to the greatest place explain
spayn [35]

In order to round 25.691 to the greatest place or the nearest whole number, first start at the last digit behind the decimal, in the case, being the 1. When it comes to things like this, if the digit is 4&under meaning its the number 4,3,2,1 or 0. If it is 5&up, that means it could be 5-9, making the digit go up (but if its 2, then the digit just goes away, you wont have to worry about that one specific number).

Next step is to round the 9 which makes the 6 go up one digit (meaning it turns into a 7). Now, when you round the seven, it will make the whole number go up one digit, but if you want to round that as well, to start, it's first rounding equaled up to 26. If you're rounding it to a whole tens number, it would be 30. I hope that this helps you understand this subject or topic much better! :3
