Answer: There is a linear relationship between the average price of PCs and the number of years that have passed since 2000.
Step-by-step explanation:
From the given graph, we can see there is a straight line , which shows that there is a linear relationship between both quantities.
As the number years increases the average price of PCs decreases.
The given equation of the line is
, which shows that the slope of the line is -39, i.e the rate of decrease in the average price of PCs with respect to the the number of years that have passed since 2000.
31 tenths is the answer because 10+10=20+1=31
No. It's rational. The solutions are +10 and -10.
A way you can set this up is like this.
1 / 2.75 = x / 3.66667
Solve for x by cross multiplying
x = 1.333
or
1 and 1/3 cups
81 is the perfect square because 9 * 9
