.

When you multiply powers with the same base, add the exponents. Do this in the denominator.


When you divide powers with the same base, subtract the exponents.

Step-by-step explanation:
h=A/b
h= 316.35/18.5
h=17.1
X - 1 is not null => x is not 1 => D = R - {1};
Answer:

Step-by-step explanation:
represent price per video game.
represent demand.
The linear equation in slope intercept form can be represented as:

where
is slope of line or rate of change of demand of game per dollar change in price and
is the y-intercept or initial price of game.
We can construct two points using the data given.
When price was $66 each demand was 400. 
When price was $36 each demand was 1300. 
Using the points we can find slope
of line.




Using point slope form of linear equation to write the equation using a given point.

Using point
.

⇒
[Using distribution]
Adding 400 to both sides:
⇒ 
⇒
The linear relationship between price and demand can be written as:
