Answer:
Yes. This equation defines y as function of x.
Step-by-step explanation:
Step 1:
Solve the equation for y (this puts the equations in terms of y)
2x+y=8 becomes
y = 2x - 8
This is a linear equation, which is a funtion.
*Another way to solve this is to look at the graph. Graphing this equation gives us a line. Use the vertical line test to see if it's a function.
To pass the vertical line test (VLT), there can only be one y value to each x value along the graph. If it passes the VLT, the equation is a function.
If it fails the VRT, the equation is not a function.
Solution :
If
is the total spending generated after n transactions, then
is the spending generated during the n-th transaction. Since the government spends D dollars, then
= D.
Then the second person will receive D dollars and spend
dollars. Therefore,
. The next person will receive
dollars, which means they are spending
dollars. Therefore,




....

∴

Answer:
Step-by-step explanation:
<u>Problems given:</u>
- - 2000 + 20.5 = - 1979.5 ≈ -1980.0 ⇒ 3 significant figures
- - 106.2 + 54.07 = - 52.13 ≈ -52.1 ⇒ 3 significant figures
Zeros at the end are not counted as significant figures
