Algebra
The inverse of -9n is dividing by -9.

Answer:I do not know because there are no number in that equation sorry
:( :(
Step-by-step explanation:
<span>y=-4/x+1 is ambiguous, since it's not immediately clear whether you meant
-4
y = -4/x + 1 or y = ---------
x+1
I'm going to assume that the latter is what you meant.
1. Interchange x and y, obtaining:
-4
x = --------
y+1
2. Solve this for y, obtaining y+1 = -4/x, or xy + x = -4, or
-x - 4
xy = -x-4, or y = ---------
x
-1 -1 4
3. Replace y with f (x): f (x) = -1 - -----
x
This last result has the correct form.</span>
Answer:
1) x= -36.
2) x = 0.
Step-by-step explanation:
1) Taking the 3rd power to both sides and using the following exponent law:

we get:

So this tells us that x = -36.
2) We can distribute the power inside every term. So the left side becomes:

Now, the trick here is to remember that
, so replacing 1 with
, which then gives us:
, telling us that 3x = 0 and thus, x = 0.
Answer: 57.5%
Step-by-step explanation:
Because....
23/40 =
23 ÷ 40 =
0.575 =
0.575 × 100/100 =
0.575 × 100% =
(0.575 × 100)% =
57.5%
* <em>Therefor, the correct answer would be 57.5% .</em>
