The correct answer is C. m-1(x) = 
You can find the value of any inverse function by switching the m(x) and the x value. Then you can solve for the new m(x) value. The end result will be your new inverse function. The step-by-step process is below.
m(x) = 5x - 5 ----> Switch m(x) and x
x = 5m(x) - 5 ----> Add 5 to both sides
x + 5 = 5m(x) ----> Divide both sides by 5
= m(x) ----> Change the order for formatting purposes.
m(x) =
And this would be your inverse, which matches answer C.
<u>Short answer</u> = C) 8/10
<u>Working :</u>
Tan A = 8/6 = Opposite / AdjacentOpposite = 8 units
Adjacent = 6 units
Hypotenuse = 
= 
= 
= 10 units
Cos B = Adjacent/ Hypotenuse
∴ cos B= 8/10
So, if 600 is 25%, that means we do 600*4=2400 600 is 1/4 of 2400.
So the answer is 2400
I hope this helps!
Answer:
5
Step-by-step explanation:
3(2n-7)=9
^ ^
6n-21=9
<u>+21 +21</u>
<u>6n</u>=<u>30</u>
6 6
n=5 :)
Well, 340/8=42.5
So you're pumping 42.5 gallons per minute.
42.5×20=850
It pumps 850 gallons in 20 minutes.
