Answer:
The correct way to set up the slope formula for the line that passes through points (5 , 0) and (6 , -6) is ⇒ C
Step-by-step explanation:
The formula of the slope of a line passes through points and
is
∵ The line passes through points (5 , 0) and (6 , -6)
∴ = 5 and
= 6
∴ = 0 and
= -6
Substitute these values in the formula of the slope
∵
∴
Let us look to the answer and find the same formula
The answer is:
The correct way to set up the slope formula for the line that passes through points (5 , 0) and (6 , -6) is
Answer:
The lesser number of workbooks are 1,000
Step-by-step explanation:
The correct question is
The profit P (in thousands of dollars) for an educational publisher can be modeled by P=-b³+5b²+b where b is the number of workbooks printed (in thousands). Currently, the publisher prints 5000 workbooks and makes a profit of $5000. What lesser number of workbooks could the publisher print and still yield the same profit?
we have
For
substitute in the equation and solve for b
Remember that the profit and the number of workbooks is in thousands
so
P=5
Using a graphing tool
Solve the cubic function
The solutions are
x=-1
x=1
x=5
therefore
The lesser number of workbooks are 1,000
<u><em>Verify</em></u>
For b=1
-----> is in thousands
so
----> is ok
