Answer:
y=3x+b
Step-by-step explanation:
finding slope:
slope= y2-y1/x2-x1
-2--5/3-2
3/1
slope is 3
i'm not sure how to find the y-intercept using this format but hope this kinda helped!
2a 3x4a +3x-5
2a+12a-15
14a-15
i think thats the answer
Answer:
The profit decreases by $ 375 for every $ 1 increase in the selling price.
Step-by-step explanation:
From the definition of the secant line we get that the average rate of change of
, where
is the selling price of the product, measured in dollars per unit, is:
(1)
Now we evaluate the function at each bound:
x = 50


x = 55


Then, the average rate of change is:


Hence, the profit decreases by $ 375 for every $ 1 increase in the selling price.
