Hi, this should be correct. Hope this helps :)
3/5 of 30 is 3/5 times 30/1=90/5=18
answer is 18 gallons
75/3000=x/4000
times both sides by 1000
75/3=x/4
times both sides by 4
300/3=x
100=x
answer is 100 hours
Answer:
27
Step-by-step explanation:
Basically how it works is that the second f() shows an x where the 3 is, so you plug 3 in for x into the equation. 3 squared or 3 to the power of 2 is 9 because 3 x 3 = 9, and 9 times 3 is 27.
Hope this helps!
INVERSE FUNCTIONS
If the f has a power of -1, then it means the inverse, or the opposite of the function, so you can either switch the y and x values in the function, as the f(x) is also used to represent y, while x is x. You can switch the function to x=3y^2.
BUT THIS IS ONLY FOR INVERSE FUNCTIONS OVER AND UP.
