Answer:
Let Lance represented by L and Nick represented by N
As per the statement:
Lance has three times as many pencils as Nick
⇒ .....[1]
It is also given that:
They have 84 pencils together.
⇒ .....[2]
Substitute the equation [1] into [2] we have;
⇒
Divide both sides by 4 we have;
N = 21
Substitute this in [1] we have;
L = 3(21) = 63
Therefore, Lance has 63 pencils and Nick has 21 pencils
Answer:
Based on the results it is expected that the slope of the tangent line at the point (0.5,10) is -20.
Step-by-step explanation:
To see that compute, the slopes for the given points as follows:
1. For we have:
2. For we have:
3. For we have:
4. For we have:
So, we observe that the slope of the tangent line at is close to the value -20.
The graph shown below is useful to see the secant lines that approximates the tangent line.
