For functions, x’s can’t repeat, so looking at the first problem, C is the only one where the first number in each coordinate (x,y) doesn’t repeat.
For the second, x = -2 means that no x is always -2 matter which y you would look at. So x’s repeat and it forms a vertical line. So it is not a function
FIRST PAGE: 20, 40, 20
SECOND PAGE: 15, 3, 6, 2 x 2 x 2 x 11
THIRD PAGE: 2 x 5 x 11
Answer:
D
Step-by-step explanation:
A, B, and C are not linear functions
D would be y=x/2
If you graphed y=x/2, you would get the points (4, 2), (7, 3.5), (8, 4), and (10, 5)
It's more obvious if you notice that y is half of x.
Answer:
Book value= $62.83
Step-by-step explanation:
Giving the following information:
A motorcycle bought for $10,000 depreciates continuously at 9% per annum.
<u>First, we need to calculate the depreciation of seven years:</u>
FV= PV*{[1+(-i/100)]^n}
FV= 10,000*{[1+(-0.09/100)]^7}
FV= $9937.17
Book value= 10,000 - 9,937.17
Book value= $62.83
