Step-by-step explanation:
f(x) = 5x – 1
To find the inverse equate f(x) to y
That's
f(x) = y
y = 5x - 1
Interchange the terms
x = 5y - 1
Make y the subject
we have
5y = x + 1
Divide both sides by 5
y = x+1/5
Therefore f^-1(x)= x + 1/5

How do you expect us to answer your question if we dont know if it is an equation but 7.0
First represent your 3 consecutive integers as follows.
X ⇒ <em>first integer</em>
X + 1 ⇒ <em>second integer</em>
X + 2 ⇒ <em>third integer</em>
<em />
Since their sum is 84, our equation reads x + (x + 1) + (x + 2) = 84.
Simplifying on the left side we get 3x + 3 = 84.
Now subtract 3 from both sides to get 3x = 81.
Dividing both sides by 3, we find that <em>x = 27</em>.
Finally, make sure you list all your answers.
If <em>x </em>is 27 then <em>x </em>+ 1 is 28 and <em>x </em>+ 2 is 29.
