Answer: 11
=========================
Explanation:
To find the inverse, or f^-1 of a function, you first replace the y= 6x-4 with x=6y-4
Finding the inverse from here is basically just finding y in terms of x.
1) x=6y-4
2) x+4=6
3) (x+4)/6= y
y= (x+4)/6 is now your f^-1.
Now that you have your inverse, replace 62 with your x in y=(x+4)/6
1) (62+4)/6
2) 66/6
3) 11
Therefore, f^-1(62)= 11
Hope this helps :)

Answer:
X=3
Step-by-step explanation:
First you have to get the x’s together. So move 3x to the left side of the equal sign and make it negative and subtract it with 6x making it 3x then move all the regular numbers together so move 5 to the right side of the equal sign and subtract by 14 and all you have left is 3x= 9 then you divide 9 by 3 and get 3 as x hope this helped have a good day ;D
50:1 scale drawing -> Both sides of the garden is shrinked by 50 times.
We can calculate the area of the shrinked scale drawing : 12 x 10.5 = 126 (cm2)
Since both sides are shrinked by 50 times -> The real area get shrinked by 2500 times.
So, we can find the real area : 126 x 2500 = 315000 (cm2)
