I believe it would be -17m-4/8
Im pretty sure your answer would be D, 6x
but tell me if im wrong.
Answer:
3 1/5 ft
Step-by-step explanation:
We can set up a proportion:
, where x is how long the pants are in real life
Cross multiply:
x = (2 2/7) * (1 2/5)
It's easier if we have improper fractions, so convert the mixed numbers into improper fractions:
2 2/7 = 16/7
1 2/5 = 7/5
Now, put these back in:
x = (16/7) * (7/5) = 16/5 = 3 1/5
Thus, in real life, the pants would be 3 1/5 ft long.
Hope this helps!
Answer:
The inverse i.e f^-1 (x) is (x-1)/2
Step-by-step explanation:
The main method for finding inverse function is as follows:
We let y =f(x), and write the function as y = 2x + 1.
Next, we swap the x and y, then rearrange to make y the subject. So i.e:
x = 2y + 1 (just swapping x and y)
x - 1 = 2y
y = (x-1)/2 (solving for x).
So f^-1 (x) = (x-1)/2
