These tables have infinitely many values, but the simplest ones would be:
a) x|y
3|5
6|10
9|15
b) x|y
2|1
4|2
6|3
Your graph for c would look like the attached picture
The probability is 8 out of 20 or 40 percent
The saying "A picture is worth a thousand words" comes to mind here. You can list all of the possible points in a solution region, or you can list a few points to give the general pattern. Though this method requires a bit more work than simply graphing and showing the solution shaded region. A visual is often more efficient at conveying a message especially to those who aren't proficient with algebra. I'm sure there are other reasons why graphs are the better choice, but that's all I could think of really.
Answer:
Rolling a die.
Step-by-step explanation:
A die has 6 sides for every answer and the only choice regarding the number 6 and you can roll (questions) times.
In this question, Adrian initially has $52,000 and his salary is 1.2 times the previous year's salary. This means the income should look like this:52000*1.2^n
30% of his income is budgeted for rent, then the equation should look like this: 30% * income= 30%*(52000*1.2^n)
Adrian's income increases by $2,300 each year as a result of gifts will make this equation:2300n
if you put the 3 equation together you will get
f(n)= 52000*1.2^n - 0.3(52000*1.2^n) +2300n
f(n)= 36400*1.2^n +2300n
