The y-intercept is 1, the slope is -2/3, so the graph is B, the second one down.
Answer:
b = 45 / 4 = 11 1 /4.
Step-by-step explanation:
We are dealing with a (30,60,90)-triangle, therefore z = 15 sqrt(3) / 2. So as well b = (15 sqrt(3) / 2) sqrt(3) / 2 = 45 / 4.
Answer:
The slope of the line that models this relationship is 0.50 US dollars per soda.
Step-by-step explanation:
At first we suppose the existence of a linear relationship between total cost (), measured in US dollars, and the number of sodas (), measured in sodas, that is:
(1)
If we know that and , then the slop of the line is:
The slope of the line that models this relationship is 0.50 US dollars per soda.
