25 movies.
So basically you start and end at 1 month so,
Galore Cost =
$10
Galore Per Movie =
0.5 x 25 = 12.5 + 10 = $22,5
Cinephile Cost =
$15
Cinephile Per Movie =
0.25 x 25 = 6.25 + 15 = 21.25
These questions are just trial and error
Assume the bigger number is x, since the difference is 18, another one should be x - 18
So the product will be x(x-18) = x^2 - 18x = (x-9)^2 - 81
Since the minimum of (x-9)^2 is 0, then the minimum of the product is -81
Answer:
It is the rate of change (how far it goes up or how far it goes down)
Step-by-step explanation:
The slope of a line is a measure of how fast it is changing. This can be for a straight line -- where the slope tells you exactly how far up (positive slope) or down (negative slope) a line goes while it goes how far across. Slope can also be used for a line tangent to a curve. Or, it can be for a curved line when doing Calculus, where slope is also known as the "derivative" of a function. Either way, think of slope simply as the "rate of change" of a graph
Example: if you have a slope of 2 your equation would be y=2x+1
You would always do rise over run. rise over run means when you put your slope in a fraction the numerator would always go up or down and the denominator would be run and run means you would go left or right. it all depends on if it is positive or negative.
Hope this helps good luck @(^_^)@
After the first day, 1/3 of the original amount remained:
... (1/3)·45 = 15
After the second day, 2/3 of that amount remained:
... (2/3)·15 = 10
