Answer:

Number 1 is a function. If you can draw a vertical line through the line graphed and it doesn't pass through it twice, it is considered a function.

Number 2 is B.

Number 3 is A. **I don't know this one for certain, but I graphed A and B for you.

I don't know number 4.

Number 5 is Beatz on Demand. This company charges $5.99 a month, while iTunez charges $8.99 a month.

Step-by-step explanation:

Below is the graph for number 3.

Answer:

1. = 3xy + x - 2y - 4

2. = d^2(2c^3-8c^2d+3d^2)

Step-by-step explanation:

= 9x^2y^2 + 3x^2y - 6xy^2 - 12xy/3xy

First factor the top equation ….

= 3xy(3xy + x - 2y - 4)/3xy

If the top and the bottom both carry 3xy, you can cancel out both of them leaving you with ….

= 3xy + x - 2y - 4

= -16c^6d^6 + 64c^5d^7 - 24c^3d^8/-8c^3d^4

First factor the top equation ....

= -8c^3d^6(2c^3-8c^2d+3d^2)/-8c^3d^4

If the top and the bottom both carry -8c^3 you can cancel out both of them leaving you with ….

= d^6(2c^3-8c^2d+3d^2)/d^4

Apply the exponent rule with d^6 ....

= d^4d^2(2c^3-8c^2d+3d^2)/d^4

cancel out d^4 ....

= d^2(2c^3-8c^2d+3d^2)

What is the slope of the line through the points (0, 0) and (2, 6)

EleoNora [17]

For this problem, you would use the slope formula, or m=(y2-y1)/(x2-x1). So, let's put in what we know.

The x's and y's correspond with our coordinates. So let's plug that in:

m=(6-0)/(2-0)
m=(6)/(2)
m=3

So, the slope of your line is 3.
