Answer:
D
Step-by-step explanation:
To find the inverse of a function, first replace f(x) with y.
Next, switch all the x's and y's, and then solve for y.
Finally, replace y with f-1(x).
Recall that
Pressure = Force ÷ Area
In this context we have,
Pressure = 24,000 ÷ (16 × 12)
= 24,000 ÷ 192
= 125 Pa
Answer:
m = -4
Step-by-step explanation:
First you have to deal with the right side of the equation since it's not spread out.
You therefore have to distribute (in order)
5×1= 5,
5×-m= -5m
And
-2×1 = -2
-2×-m = 2m
Now set it up in the order it was at first (not necessary, but helpful)
15 = 5-5m-2+2m
Add the common values...
5-2= 3
-5m+2m= -3m
Your equation should now look like this:
15= 3-3m
At this point you need to get the common values on the same side, so you would subtract 3 from both sides
15-3= 12
3-3= 0
Since you the 3 cancelled out on the right side, your equation now looks like this:
12= -3m
(Or -3m= 12)
At this point you only need to get m by itself so you would divide by -3 on both sides
-3m/-3= m (or 1m: m is understood as such)
12/-3= -4
The final answer should be
m = -4
