Answer: x = 27
Step-by-step explanation:
x/3 - 11 = -2
Add 11 to each side
x/3 = 9
Multiply each side by 3
x = 27
x cannot equal 21.
21/3 - 11
21/3 = 7
7 - 11 = -4
-4 does not equal -2
Therefore, x cannot equal 21.
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.
35 divided by 7 is 5 and 42 divided 7 is 6 ... it should actually be 5:6
