(9) The correct Option is (C) 4, -3Explanation:The left hand limit is:

+4 because the line(y=+4) is constant if limit approaches to 2 (from left side of the graph)
The right hand limit is:

-3 because the line(y=-3) is constant if limit approaches to 2 (from the right side of the graph)
So the correct Option is (C) 4, -3
(10) The correct Option is (C) -4
Explanation:

The plus sign in the limit indicates that it is the right hand limit. So we have to approach to 3 from the right side of the graph. When we do that, we see the constant line y = -4. Hence the correct option is (C)
NOTE: Although the question seems complex because there is slope involved but in this particular case, the examiner is concerned about the
right hand limit. If she or he asks the left hand limit(3-minus) then we would take the slope-line.
P.S. Sorry for bit late reply! I thought somebody answered it already! :)
Answer:
There is not enough information to be able to answer this
Step-by-step explanation:
3 times the 6th power of 10
Lets step by step convert the word form to an expression
You have to multiply 3 by the 6th power of 10, so
3 * 6th power of 10
In the 6th power of 10, 10 is the base and it is to the power of 6, so it can be reworded to 10 to the 6th power
or 
We have to multiply it by 3
So the written expression is
3 * 
Answer:
(A)If x represents the number of songs she downloads then it is a variable because of the AMOUNT of songs she downloads.
Step-by-step explanation:
For example if we had f(x)=2 the equation would be c=4.99+.75(2)
.75*2=1.50+4.99=
(6.49 = c) cost per month if she downloads 2 songs
