Answer:

  see attached

Step-by-step explanation:

a) A system of equations has no solutions when the graphs of those equations do not intersect. If the equations are equations of a line, then the lines must be parallel in order for them not to intersect.

Any parallel line will do.

__

b) There is one solution when the graphs intersect in exactly one point.

Any line that crosses the one shown will do.

__

c) There are infinite solutions when the graphs describe the same curve.

A line overlapping the one shown is the one you want.

Explanation:

Angles 1 & 2 have to equal 180. So, if ∠1 is equal to 140, ∠2 is equal to 40 because 140 + 40 = 180.

So far... we know that:

  • ∠2 = 40
  • ∠9 = 80

Angles 2, 9, and 11 make a triangle, a triangles "magic number" is also 180. To get 180, you must add up all of the angles. Well... we don't know ∠11 so to find it, you subtract 40 & 80 from 180. 180 - 80 - 40 = 60.

Answer:

∠2 = 40

∠11 = 60

The scatter plot shows the number of DVDs Aaron sold in different months:
netineya [11]
We'll say that months = n. 

Make a set of the DVD's sold:

{20, 50, 80, 110, 140...}

In month 1, Aaron sold 20 DVDs. There is no data for month 0.

There is a constant increase of 30 DVDs every month. We can make an equation out of this to fit this data set:

a = 30n - 10

a represents the DVDs made.

We need to subtract 10 in this equation, as the starting point is 20, and the increase of 30 is different from the increase from n = 0 to n = 1.

We are looking for the amount of DVDs Aaron sold on the 13th month. Plug 13 into the equation:

n = 13
30(13) - 10 = 390 - 10 = 380

The predicted number of DVDs Aaron will sell on the 13th month is 380.
