Answer:
Yes, y=5x is a direct variation and the constant of variation is 5 .
I believe B But I am not sure I hope this helps . =D
y^2 = x isn't a function because there is at least one value of x that produces multiple values of y. In fact, any x value greater than 0 yields two y values. If x = 0, then y = 0 is the only solution. ... Graphically, the equation fails the vertical line test, which is another way to determine that it is not a function.
Usually, the terms “data” and “information” are used interchangeably. However, there is a subtle difference between the two.
In a nutshell, data can be a number, symbol, character, word, codes, graphs, etc. On the other hand, information is data put into context. Information is utilised by humans in some significant way (such as to make decisions, forecasts etc).
A basic example of information would be a computer. A computer uses programming scripts, formulas, or software applications to turn data into information.
Let us have a detailed look at the difference between data and information in a tabular column below
(2x+4)+(4x+2)+(2x-1)=180
8x+5=180°
8x=180-5
8x=175
X=21.875
A= 2(21.875)+4=47.75
B=4(21.875)+2 =89.5
C=2(21.875)-1=42.75
