She needs to earn at least 84 to buy the mp3 player
earnings=earningsperhour times numberofhoursworked
earnings per hour=12 dollars
number of hoursworked=h
therefor
earnings=12 ties h or12h
earnings is at least 84
earnings is greater than or equal to 84
earnings<u>></u>84
12h<u>></u>84
solve
12h<u>></u>84
divide both sides by 12
h<u>></u>7
she needs to work at least 7 hours
to graph, draw a line at x=0 and shade to the right, make the line solid
Note: Options are missing. So, the general solution of the given inequality is shown below.
Given:
The inequality is:

To find:
The point lies in the solution set of the given inequality.
Solution:
We have,

It can be written as:




All the points that satisfy the above inequality are in the solution set of the given inequality.
For example (0,0).


This statement is true. It means (0,0) is in the solution set.
For example (0,3).


This statement is false. It means (0,3) is not in the solution set.
The graph of the inequality
is shown below.
All the points in the shaded region are in the solution set but the points on the boundary line are not in the solution set.
