Answer:
11.V=-2
12.X=6
13.A=9
14.X=-4
15.A=-5
16.P=3
17.K=6
18.M=0
Step-by-step explanation:
Subtract the number on each side to get the variable by itself or add depending on if it has a plus or minus on the side with the variable.
Hope this helps!

Answer:
x = -3
In-Depth Steps:
1.) Start with the bottom equation: 
2.) Set
alone on one side of the equal sign. Your equation will look like
.
3.) Plug
in for
in the first equation. You will get
.
4.) Distribute. Your equation now looks like this:
.
5.) Combine like terms. You will get
.
6.) Subtract 6 from both sides. You get
. We can learn that Y=0.
7.) Go back to either equation and put 0 in for y.
8.) In the top equation, it would look like
and the bottom equation would look like
. We basically got our answer of
, but we will plug it into the
equation, and in-fact, we get x = -3.
.28 if 1 was 100,and .28 was 2.8, then we divide 100 by 100 same for 2.8
Given:

To find:
The correct function.
Explanation:
Let us consider the function given in option D.

Differentiating with respect to x we get,

Substituting x = 2 in the function f(x), we get

Therefore, the given conditions are satisfied.
So, the function is,

Final answer: Option D
63% decrease.
0.63•80=50.4kg
80kg-50.4kg=29.6kg
