3(m-2)=5(m-4)
3m-6=5m-20
3m-5m=-20+6
-2m=-14
-m=-7
m=7
I hope this is what you need..
Answer:
77 feet below sea level.
Step-by-step explanation:
Since y is the time the submarine is ascending, we can plug it in for y and find our answer. We can create an equation where D is the depth and y is time ascending: D = -230 + 17y
Substitute 9 for y:
D = -230 + 17(9)
D = -230 + 153
D = -77
The depth of the submarine after 9 minutes will be 77 feet below sea level. Hope this helps, and Brainly will be highly appreciated.
Answer:
m = -1/2

Answer:
D is -31 also i checked to make sure.
we are given
For finding inverse function , we do following steps
step-1:
Set f(x)=y
step-2:
Switch x and y
step-3:
now, we can solve for y
Multiply both sides by 9y-2
Add both sides by 2x
now, we can divide both sides by 9x
so, we get inverse function as
