D. 5x = 45 because you are trying to find x, the number of tickets that must be sold to earn $45.
For this we will use equation:
H = starting height + rate_of_growth*periods
We can mark H with index w to represent how many weeks have passed.
Because all of this we can write:
Hw = 200 + 0.5*w
To calculate height after some number of weeks all you need to do is to exchange w with number of weeks.
It should be about 16.67% (or 17%) of it.
Answer:
{x,y}={6,1}
Step-by-step explanation:
Answer:

Step-by-step explanation:
Choosing two points on the dotted line to find equation of line.
The points are:
and 
Slope of line can be calculated as:



Using point slope equation to find equation of dotted line.

where
represents slope of line and
represents y-intercept.
The y-intercept for the dotted line = 6 as it intersects the y-axis at (0,6)
So, the equation of line is:

The dotted line indicates that the line is not included in the solution.
The solution of the inequality is below the dotted line, so thus it would be less than the line.
So, the inequality would be:
