Answer:
= (-2,5)
Step-by-step explanation:
To Find: 
Solution :
Referring the given graph
We can find the coordinates of
and 
Coordinates of
= (-7,1)
Coordinates of
= (5,4)
Thus Coordinates of
= (-7+5,1+4) = (-2,5)
Thus
= (-2,5)
So, the point
= (-2,5) is shown on the attached graph file
Answer:
1
Step-by-step explanation:
If you are just looking for the derivative, then all you need to use the power rule for this. Technically the x in (x-9) has a power to the 1, so really x^1-9. To use power rule, you bring down the exponent, in this case, 1, and then minus 1 from what the exponent was.
1x^(1-1) = 1x^0. The derivative of any constant is 0, so don't even worry about the -9. We know that anything raised to the zero is just 1, so in this case your answer is 1.
Hope this helps :)
For this case we must simplify the following expression:

We eliminate the parentheses taking into account that:

We add similar terms taking into account that:
Equal signs are added and the same sign is placed.
Different signs are subtracted and the major sign is placed.

Answer:

The answer is $213 because you subtract the price sold by the price he bought them for and then you add them together (see work)
