Easy, take:
p-4=-9+p
Isolate the variable, this is what you are trying to find (p)
p-4=-9+p
-p -p
-4=-9.
There is no variable, which means, there is NO SOLUTION!
You can put no solution, or ∅, as an answer.

Step-by-step explanation:</h3>

Substitute into one of the equations

Rearrange variables to the left sider of the equation

Combine like terms

Divide both sides of the equation by the coefficient of variable

Determine the sign for multiplication or division

Cross out the common factor

Substitute into one of the equations

The solution of the system is

Step-by-step explanation:
Choosing the coaches of the basketball teams is independent because which girl he chooses does not influence nor is it influenced by the choice for the boy
PART A:
Find the rate of change between 1980 and 1989
d for P₁ = 80 - 60
d for P₁ = 20
d for P₂ = 76 - 82
d for P₂ = -6
The rate of change in P₁ is 20 hundred per year. The rate of change in P₂ is -6 hundred per year.
PART B:
Find the rate of change between 1989 and 1996
d for P₁ = 100 - 80
d for P₁ = 20
d for P₂ = 70 - 76
d for P₂ = -6
The rate of change in P₁ is 20 hundred per year. The rate of change in P₂ is -6 hundred per year.
PART C:
Find the rate of change between 1980 and 1996
d for P₁ = 100 - 60
d for P₁ = 40
d for P₂ = 70 - 82
d for P₂ = -12
The rate of change in P₁ is 40 hundred per year. The rate of change in P₂ is -12 hundred per year.
